TC620-PID
Page 12
Optical safety
The following optical safety information applies to TC620-PID models with SFP interface.
This product complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to Laser
Notice No. 50, dated June 24, 2007. This optical equipment contains Class 1M lasers or LEDs and
has been designed and tested to meet IEC 60825-1:1993+A1+A2 and IEC 60825-2:2004 safety
class 1M requirements.
Warning: Optical equipment presents potential hazards to testing and servicing personnel, owing
to high levels of optical radiation.
When using magnifying optical instruments, avoid looking directly into the output of an
operating transmitter or into the end of a fiber connected to an operating transmitter, or there
will be a risk of permanent eye damage. Precautions should be taken to prevent exposure to
optical radiation when the unit is removed from its enclosure or when the fiber is disconnected
from the unit. The optical radiation is invisible to the eye.
Use of controls or adjustments or procedures other than those specified herein may result in
hazardous radiation exposure.
The installer is responsible for ensuring that the label depicted below (background: yellow;
border and text: black) is present in the restricted locations where this equipment is installed.
EMC
This device has been tested and found to meet the CE regulations relating to EMC and complies
with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device
may not cause harmful interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation. These limits are designed to provide
reasonable protection against interference to radio communications in any installation. The
equipment generates, uses, and can radiate radio frequency energy; improper use or special
circumstances may cause interference to other equipment or a performance decrease due to
interference radiated by other equipment. In such cases, the user will have to take appropriate
measures to reduce such interactions between this and other equipment.
Any interruption of the shielding inside or outside the equipment could make the equipment
more prone to fail EMC requirements.
Non-video signal lines must use appropriate shielded Cat 5 cabling (S-FTP), or at least an
equivalent. Ensure that all electrically connected components are carefully earthed and
protected against surges (high voltage transients caused by switching or lightning).
ESD
Electrostatic discharge (ESD) can damage or destroy electronic components. Proper precautions
should be taken against ESD when opening the equipment.
Care and maintenance
The unit will normally need no maintenance. To keep it operating reliably:
Prevent dust from collecting on the unit.
Do not expose the equipment to moisture.
Safety and compliance
Page 13
Handle the camera carefully
Do not abuse the camera. Avoid bumping and shaking. The camera can be damaged by improper
handling or storage.
Do not disassemble the camera
To prevent electric shock, do not remove screws or covers. There are no user serviceable parts
inside. Consult technical support if a camera is suspected of malfunctioning.
Do not use strong or abrasive detergents to clean the camera
Use a dry cloth to clean the camera when it is dirty. If the dirt is hard to remove, use a mild
detergent and wipe gently. To clean the lens, use lens tissue or a cotton tipped applicator and
ethanol. Do not clean the lens with strong detergents.
Never face the camera towards the sun
Do not aim the camera at bright objects. Whether the camera is in use or not, never aim it at the
sun or other extremely bright objects, as this can damage the camera.
RoHS statement
Global concerns over the health and environmental risks associated with the use
of certain environmentally-sensitive materials in electronic products have led
the European Union (EU) to enact the Directive on the Restriction of the use of
certain Hazardous Substances (RoHS) (2002/95/EC). Siqura offers products
that comply with the EU’s RoHS Directive. The full version of the Siqura RoHS
statement can be viewed at www.siqura.com.
Product disposal
The unit contains valuable materials which qualify for recycling. In the interest
of protecting the natural environment, properly recycling the unit at the end of
its service life is imperative.
When processing the printed circuit board, dismantling the lithium battery calls
for special attention. This kind of battery, a button cell type, contains so little
lithium, that it will never be classified as reactive hazardous waste. It is safe for
normal disposal, as required for batteries by your local authority.

3 Product overview
This chapter introduces the TC620-PID and its features.
In This Chapter
Features ........................................................................... 15
Description ........................................................................ 15
3.1 Features
TC620-PID
Integrated thermal IP camera
Built-in Perimeter Intrusion Detection
i-LIDS® certified for primary sensor in
sterile zone
ONVIF Profile S conformant
Video resolution: 336x256
Robust aluminium housing
3.2 Description
The Siqura TC620-PID is in itself a complete solution for perimeter intrusion detection. It is built
around a thermal LWIR sensor and on-board analytics for accurate detection of unwanted
intrusions. By using thermal vision, detection is possible in all weather, no-light, and difficult
lighting conditions. The TC620-PID comes as an outdoor camera (IP66).
Intrusion detection
The embedded ObjectR-Advanced PID analytics is i–LIDS® certified and approved to be used as
primary sensor in a sterile zone. Through the web interface, configuration of the
ObjectR-Advanced PID analytics is straightforward with either two detection lines or two
detection zones. To get the most out of the PID analytics Siqura offers the VCA Configuration
Server. By using a thermal sensor the influence of external factors is limited to a minimum.
Decision making and situational awareness
Do you often feel that you have lost control? This occurs when – in a mission-critical environment
where split-second decision making is crucial – you expect something to happen but it does not.
Your expectations are based on all the data that is presented to you and its history. To make the
right decision you need to be aware of the environment around you and have access to
information relevant only for that specific situation – not the enormous amount of useless data
you get when watching 24 CCTV monitors simultaneously, for example. The TC620-PID extracts
useful information from the scene and presents it in the video image itself to a video
management system, such as VDG Sense.
TC620-PID
Page 16
VDG Sense
The Siqura TC620-PID works seamlessly with the VDG Sense video management system. It
supports forensic search by storing the PID object data next to the video. The PID events are
triggers to the powerful VDG Sense macro engine, which enables you to define how the system
should react during certain events. You can set macros to have VDG Sense automatically pop up
a camera to inform the operator of an intrusion alert.
VCA Configuration Server (VCS)
ObjectR-Advanced PID detection analytics physically runs in the Siqura edge devices. This
detection engine, however, is much more powerful when configured by the Siqura VCA
Configuration Server. The configuration server adds more detection templates, such as eight
zones or lines. The VCS is capable of storing up to 64 channels of video and object data. Forensic
searches are done using the stored object data which speeds up the search up to 10,000 times
faster than real-time. This feature is also used to find the best configuration for a camera using
the real footage. This configuration is uploaded in the TC620-PID, with the best performance and
reliability for the perimeter intrusion detection.
Thermal imaging
It is possible to use standard CCTV cameras for video analytics but it requires experience and
knowledge of the analytics to position them. All sorts of distractions, such as the headlights of a
car, can cause false alerts. In certain situations, image clarity is compromised when using visible
light cameras, which may result in degraded automatic intruder detection.
Lighting conditions do not pose any problems for the TC620-PID thermal camera. It does not
‘see’ shadows and light beams. It picks up the heat (deep infrared) radiated by the objects
themselves.
Field-hardened
The ruggedised and vandal-resistant die-cast aluminium housing has an IP66 ingress rating to
ensure optimal protection in harsh environments.
Open Streaming Architecture (OSA) and ONVIF
The TC620-PID is designed with OSA offering standardised streaming video and remote control
based on international standards and tested with different vendors. A comprehensive HTTP API
gives access to all controls and makes integration easy. The TC620-PID also fully supports
ONVIF and is listed as ONVIF Profile S conformant.
Web interface
Configuration, management, and live viewing are simplified by the access-controlled web
interface. Full in-band control is available through Siqura Device Manager, Siqura’s MX™
Configuration Tool Kit, and the HTTP API. The TC620-PID is field-upgradeable.

FTP push
Upon an event, the TC620-PID can push a JPG image to one or two FTP servers. The event can
be triggered externally by Perimeter Intrusion Detection, VMD, or Tamper Detect. The
TC620-PID can also periodically upload images to the remote server(s).

4.1 ONVIF
The Open Network Video Interface Forum (ONVIF) is an open industry forum for the
development of a global standard for the interface of IP-based physical security products. ONVIF
is committed to the adoption of IP in the security market. The ONVIF specification ensures
interoperability between products regardless of manufacturer. It defines a common protocol for
the exchange of information between network video devices including automatic device
discovery, video streaming and intelligence metadata. The TC620-PID fully supports ONVIF. It
has been tested to support ONVIF Profile S.
4.2 OSA
Siqura's Open Streaming Architecture (OSA) consists of a standard set of open communication
protocols to govern media streaming via RTSP and equipment management via HTTP. OSA
enables easy integration of the TC620-PID with third-party products. The protocol consists
mainly of different CGI (Common Gateway Interface) program calls for listing and configuring
parameters. A detailed description of the HTTP API is given in the Siqura Programming Interface
specification which can be downloaded at www.siqura.com.
4.3 Web UI
Using the TC620-PID's web server is the most straightforward way to access the unit. The
webpages enable you to configure the settings of the TC620-PID and view live video images from
a standard web browser.
TC620-PID
Page 20
4.4 MX/IP
MX/IP is a proprietary Siqura protocol which gives direct access to the settings of the TC620-PID.
Using special MX software, such as MX Configuration Tool, TC620-PID settings can be read from
and written to the Management Information Base (MIB), a list of variables stored inside the unit.
Offering full control of the TC620-PID, the MIB enables you to remotely configure device settings
and manage media streams. Additional MX viewing and control software offers real-time
monitoring of video streams and playback of recorded images. For more information about
MX/IP, the MIB, and Siqura's EMX network service, refer to the manuals which document the MX
SDK and the MX applications.
Note: If you prefer using open standards, you can disable the MX/IP protocol. This is done on the
MX tab of the Device Management page. Be aware that doing so prevents you from upgrading
the TC620-PID firmware through MX Firmware Upgrade Tool.
4.5 SNMP
The Simple Network Management Protocol (SNMP), part of the internet protocol suite, can be
used to monitor network devices such as the TC620-PID for conditions or events that require
administrative attention. For more information, refer to appropriate literature on SNMP.
The TC620-PID supports in-band SNMP. Via SNMP, several status variables can be read and
traps can be generated on events. You can configure TC620-PID SNMP settings on the SNMP tab
of the Device Management page.
The SNMP Agent is MIB-2 compliant and supports versions 1 and 2c of the SNMP protocol.
Note: The TC620-PID includes SNMP support for its tamper detect function. A trap is sent when
camera tampering is detected.
Required MIB files can be downloaded at www.siqura.com.
4.6 SAP
The TC620-PID supports the Session Announcement Protocol (SAP), a protocol used for
broadcasting multicast session information. A SAP listening application can listen to the
announcements advertised by the TC620-PID SAP announcer. The application can use this
information to receive a video or audio stream that the TC620-PID is transmitting to the
advertised multicast address. For more information, see the description of the Video and Audio
pages.
4.7 NTCIP
The National Transportation Communications for ITS Protocol (NTCIP) is a communication
protocol deployed in Intelligent Transportation Systems (ITS) in the USA. It is a family of
standards designed to provide definitions of common data elements and communication
protocols for the interaction between traffic management centre(s) and road-side devices such
as cameras, traffic signals, and highway lighting. The goal of the standards is to achieve
interoperability and interchangeability between systems manufactured by different vendors in
order to reduce the total cost of traffic systems, including maintenance.
The TC620-PID supports all the mandatory parts and some of the optional parts of the NTCIP
CCTV specification as laid down in the NTCIP 1205:2001 v01.08 document. For details about the
NTCIP configuration of the TC620-PID, see Appendix: NTCIP Configuration.
Interfaces
Page 21
The TC620-PID supports the standard NTCIP SNMP MIB. This MIB database is used to store
information, which in turn will be used to control cameras and other devices in the transportation
management system. An electronic version of the MIB is available from a NEMA FTP site. To get
access to the FTP site, send your name, organisation name, and email address to
ntcip@nema.org, and request access.

5 Stream media via RTSP
The easiest way to extract a video or audio stream from the TC620-PID is to use the Real-Time
Streaming Protocol (RTSP). This chapter explains the role of the TC620-PID in RTSP media
sessions and describes how to open a media stream from the unit in a video player plug-in.
In This Chapter
RTSP and RTP .................................................................... 23
Transfer via UDP or TCP ...................................................... 24
5.1 RTSP and RTP
The TC620-PID implements an RTSP server. A hardware or software decoder (the latter within a
viewing application, for example) is the RTSP client. Media sessions between client and server
are established and controlled with RTSP. Media stream delivery itself is handled by the
Real-Time Transport Protocol (RTP). The TC620-PID supports video and audio streaming via UDP
and TCP.
Use the following URL format to get a video stream into, for example, VLC or QuickTime.
rtsp:// <IP address of encoder>:<RTSP Port>/VideoInput/<x>/<y>/<z>
where:
<x> is the number of the Video Input
<y> is the media type of the required encoder
<z> is the encoder number
Note: The <RTSP Port> is optional. If not entered, port 554 is used by default.
Note: The encoder number index <z> in the URL only takes enabled encoders into account, with
the encoder mode set to the indicated media type <y> (RTSP is a streaming protocol which
takes care of stream control; it does not handle device configuration).
The stream in the following figure will be pulled from the unit with the IP address 172.22.250.39,
using Video Input 1 and the first enabled H.264 encoder.
TC620-PID

5.2 Transfer via UDP or TCP
The TC620-PID supports the following types of streaming.
UDP/IP (multicast and/or unicast)
TCP/IP (RTP, RTP over RTSP, RTP over RTSP over HTTP)
The TC620-PID reports to the client that it supports transfer over UDP and TCP. The choice is
made on the client side. In VLC, for example, using a TCP connection can be forced (Preferences
> Inputs and Codecs > Network > RTP over RTSP (TCP)).
For details on controlling TC620-PID media streams through HTTP and RTSP, refer to the Siqura
Programming Interface specification. You can download this HTTP API specification at
www.siqura.com.

9 PID
The TC620-PID is a complete solution for perimeter intrusion detection. This chapter explains
how to use the web interface to configure the on-board analytics for accurate detection of
unwanted intrusions.
In This Chapter
PID .................................................................................. 35
9.1 PID
PID
Perimeter Intrusion Detection (PID) is an early warning application which triggers an alert when
a predefined perimeter within the area monitored by the TC620-PID is violated. The PID video
analytics uses configurable detection zones, detection lines, and object size with perspective
correction to identify and track an object through the camera scene. The video content analysis
algorithms continuously monitor the video images and decide when to issue an alert.
Through the Event Management webpage, PID events can be associated with a CC Output, a CC
Stream, or an FTP Push event to notify an operator in a control room of security issues. Once
alerted, it is up to the operator to assess the specific event and undertake appropriate action.
TC620-PID
Page 36
9.1.1 Camera installation
The following sections describe how to use the PID page to set up the PID functionality. However,
before you are ready to embark on this task, it is imperative to make sure that the camera is
properly installed for PID application.
Installing cameras and lighting for surveillance purposes requires specific professional skills. The
requirements for camera images processed with automatic PID functionality differ significantly
from the requirements for images monitored by human observers.
For example, in conventional surveillance camera setups, the camera is often aligned such that
it provides a clear overview of the entire site, including a natural horizon showing some of the
sky. For PID purposes, however, the only relevant part of that image is the detection zone. All
other parts of the image are irrelevant and can decrease PID sensitivity, because they leave
fewer pixels for the objects within the detection zone, thus potentially leading to degraded
detection performance.
Also, for example, sky in the image causes the Automatic Gain Control (AGC) of the camera to
adjust, possibly degrading the image in which objects are to be detected.
9.1.2 Siqura PID solutions
PID detection can be active in an edge device, such as the TC620-PID, or in a remote server. The
detector analyses the images and separates the moving objects from the background. These
objects are called ‘blobs’. By adding detection lines or detection zones, specific rule sets are
applied on the blobs triggering events, which can be read by VDG Sense or other video
management systems.
Siqura offers a variety of intrusion detection solutions:
Stand-alone Siqura PID device
Siqura PID device(s) and VDG Sense VMS
Siqura PID device(s) and VCA Configuration Server (VCS)
9.1.2.1 Stand-alone solution
Stand-alone Siqura PID devices (3x camera with PID, 1x video encoder with PID)
The TC620-PID can run stand-alone. The device offers an intuitive web interface to draw the
multipoint detection lines or zones in the image as described later in this chapter. The detection
is limited to either two direction-sensitive multipoint detection lines or two multipoint detection
zones.

9.1.2.2 TC620-PID/VDG Sense solution
TC620-PID/VDG Sense solution
In the TC620-PID/VDG Sense solution, detection is done either in the TC620-PID or in VDG
Sense if other (non-PID) IP cameras are connected. In both cases VDG Sense can be used for
configuration and recording of the blob stream.
The VCA features available together with VDG Sense are:
Super fast forensic search on the recorded images
8x Multipoint detection zones
4x Multipoint detection lines, direction sensitive

9.1.4.3 Shapes
To establish the exact dimensions and position of the area(s) to be monitored for events, you
overlay shapes over the preview.
Shapes come in three categories.
trigger shape
ignore shape
helper shape
Trigger shapes are used to define the area where objects can trigger an event. Ignore shapes do
the opposite. They suppress the triggering of events. Helper shapes are used to provide a visual
(graphical) input for object size.
The following overlays are available.
Detection zone (trigger)
Detection line (trigger
Ignore line (ignore)
Perspective (helper)
Minimum object size filter (helper)
Detection zone
A detection zone shape is initially drawn as a box, but nodes can be added to allow for more
complex shapes. Trigger conditions can be set through the context menu of the zone.
Detection zone shape
Detection line
A detection line is a single line between two points which triggers when an object crosses it. Extra
nodes can be added to provide a more flexible line. Trigger conditions can be set through the
context menu of the line.
TC620-PID
Page 40
Detection line shape
Ignore line
The ignore line is a single line between two points which can be placed to suppress the triggering
of an event for a limited amount of time. An ignore line suppresses all triggers from all objects.
Trigger conditions can be set through the context menu of the line.
Perspective
The perspective shape is used to establish the perspective of the scene. To make calculations of
the perspective correction as accurate as possible it is best to draw it in a part of the scene that
shows the perspective, the bottom line and the top line of the shape must run parallel.
Correct placement of perspective shape
Minimum object size filter
The Minimum object size shape describes the size of the required objects. If used in combination
with the Perspective shape the Minimum object size shape will be perspective corrected.

To display detected objects and/or alarms in the preview
In Web configuration, select the respective option(s).
Detected objects are shown in blue. Alarms are highlighted in red boxes.
9.1.4.7 Glue events
If consecutive events occur with short intervals it may be more efficient to "glue" them together.
This means that one longer event is generated.
To set the glue events time
In the Settings section of the PID page, specify the Glue events time in the Glue events
within box.
The effect of the glue time is that for a given event the start time remains the same, but the
peak time and end time are pushed forward in time for every glued event. When the event
is retrieved, the peak time will be that of the last glued event.

10.1.1 Stream states
The Status tab provides information on the stream states of video and audio streams. A stream
state is reported as Idle, Waiting, or OK.
Stream state
Description
OK
There is nothing wrong with the stream.
Note that if the video signal is removed from the video input on the encoder side,
the Decoder rx state is still reported as OK, since the video transmitter is sending
a stream, that is - a No Video image - to the decoder.
Idle
The transmitter/receiver is not enabled.
Waiting
The transmitter/receiver has lost its stream connection.
Possible causes:
An incorrect port number.
The transmitter on the encoder side is not enabled.

On the Network page, you can change the network settings of the TC620-PID. In this chapter,
you learn how to set a valid, fixed IP address and, alternatively, how to have an IP address
automatically assigned by a DHCP server.

11.1 Network settings
Network page
On the Network page, you can set the name of the unit, the IP address, the subnet mask, and the
gateway IP address. For correct functioning of the TC620-PID, it is vital to set its network
addressing to be compatible with the subnet it is hooked into.
Note: The factory-set IP address of the unit is in the 10.x.x.x range with a subnet mask of
255.0.0.0. Achieving initial communication with the unit requires that the network adapter of the
browsing PC is set to the factory-default subnet of the TC620-PID. Once you have made the
webpages accessible in this way, you can use the Network page to change the default network
settings to the desired settings.
For IP address input to be valid, the unit's IP address:
must be within the 1.0.0.1 – 223.255.255.254 range
cannot start with 127 (reserved for loopback on local host)
After changing IP settings, do not forget to save the new settings and reboot the unit (see
chapter Device Management).
Important: It is essential to set at least the IP address and subnet mask correctly. Keep these
value on record, otherwise management of the unit will require special software.

Calibration
The sensor inside the TC620-PID detects differences in temperature. To compensate for
temperature drift and to maintain reliable detection, it must be calibrated at regular intervals.
The image freezes for a second during calibration. Using the options in the Max calibration
interval list, you can control the calibration interval duration to meet the ambient conditions.
Max AGC gain
The presets in the Max AGC gain list can be used to optimise the signal level and brighten video
images to compensate for low-contrast conditions. Note, however, that setting the level to High
can introduce noise into the picture.

12.2 Video encoding overview
Encoder tabs on Video page
Video encoding
The TC620-PID features a built-in video server. Two video encoders can simultaneously
generate independent digital video streams with different resolutions and frame rates. Encoders
1 and 2 can each convert the video signal into H.264 or MJPEG format.
Multistreaming
Up to twenty streams can be retrieved using RTSP. A total of six copies – three per independent
encoder – can be transmitted to different unicast and/or multicast destinations using Siqura's
proprietary MX protocol. The TC620-PID supports source-specific multicast (SSM). H.264 and
audio streams can also be transmitted to multicast destinations using the Session
Announcement Protocol (SAP).
Live View encoder
The Live View encoder can convert the analogue video input signal to (M)JPEG format for
streaming to web applications or remote devices using the HTTP protocol. Via FTP Push, JPEG
images can also be posted on an FTP server.

Encoding mode
H.264 or MJPEG
The method used to compress the video signal.
TC620-PID can stream (M)JPEG over UDP and HTTP.
To enable and configure UDP/MJPEG streaming, select MJPEG from the
Encoding mode list and configure settings.
To transport JPEG over HTTP and/or use the Live View previews in the web
pages, go to the Live View tab, enable the Live View encoder, and configure its
settings.
Video bit rate mode
Controls variations in bit rates.
Constant quality
Keeps the image quality constant, with varying network
load. See Constant Quality Mode (CQM) configuration
(below) for Siqura's recommended strategy for controlling
image quality.
Constant bit rate
Keeps network load constant at the cost of varying
image quality. Frames may be skipped.
Note: The TC620-PID will simultaneously handle dual H.264/MJPEG encoding at full frame
rate, and Live View encoding at 5 frames per second. The total output bandwidth, including
streams controlled by RTSP, and those enabled through SAP, should not exceed 25 Mb/s.
GOP length
Distance in frames between two I-frames.
Frame rate
Range depends on selected front end : 1-7.5 fp (-S models) or 1-30 fps (-F models).

This field is dynamically updated with the current bit rate to
provide feedback on the bit rate that is used on average
with the current Quality setting.
Quality

12.3.2 Parameter value combinations
Set sensible combinations of video bit rate mode, resolution, GOP length, and frame and bit
rates. When you set and save these values, inappropriate value combinations are 'corrected' by
automatic selection of the closest suitable combination.
Important: If in doubt about the effects of specific encoder settings, you are advised to select the
profile offering the closest match to your required application.
12.3.3 Constant Quality Mode configuration
Constant Quality mode (CQM) can be used in situations with intermittent increases of movement
in camera images. This mode provides better pictures when quickly panning a PTZ camera, for
example. Siqura recommends the following strategy for Constant Quality mode configuration.
To configure CQM settings
1. In Encoder Settings, open the Video bit rate mode list, and then select Constant quality.
2. With the video source connected and the encoder enabled, go to the Quality field and set the
desired quality (range: [0 ... 100%]), aided by the visual feedback in the Preview.
3. Press Save to store your settings.
The Actual bit rate field is dynamically updated with the current bit rate.
4. Determine if the average bit rate used with the current Quality setting is acceptable. If not,
modify the Quality setting.
5. To set the upper limit for the bit rate, open the Advanced Settings section and use the CQM
max bit rate field to specify the maximum bit rate.
Generally, it is not necessary to change the default setting of 6000 kbit/s, unless there are
physical limitations on the network.
6. Press Save to store your settings.

12.3.4 Make a video connection
Creating a video link between a video encoder and a video decoder involves two steps:
Configuring settings of the encoder
Configuring settings of the decoder
To configure the encoder settings
1. Open the webpages of the encoder, go to the Video page, and then open the appropriate
Encoder tab.
2. In the MX Transmitter Settings section, specify the destination IP address.
This is the address of the video decoder which will receive the video stream.
3. Enter the port number of the decoder.
For more information about port numbers, see the Port Numbers section.
4. Select Enable, and then click Save.
Video Transmitter Settings (encoder side).
Transmitter 1 enabled, holding the decoder IP address and input port number.
An input port number must be used only once per device.
To configure the decoder settings
1. Open the webpages of the decoder, go to the Video page, and select the Decoder tab.
2. In the MX Receiver Settings section, specify the source IP address.
This is the address of the video encoder which will transmit the video stream.
3. Enter the port number of the decoder.
For more information on port numbers, see the Port Numbers section.
4. Select Enable, and then click Save.
Video Receiver Settings (decoder side).
Receiver 1 enabled, holding the encoder IP address and the decoder input port number.
An input port number must be used only once per device.
With these settings configured correctly, the video link is established. The decoder takes the
video stream from the encoder, detects the video format and uses the appropriate decoding
algorithm to convert the stream to an analogue output signal.
Note: Source and destination IP addresses can be unicast or multicast. For more information, see
the Multicast chapter.
Highlighted fields
The source address and port number fields are highlighted in green when the enabled receiver
receives a stream from the specified source. The two fields are marked in red when no stream is
received with the receiver enabled and correctly configured.
SDP download
Use the SDP Download button to download a Session Description Protocol (SDP) file from the
encoder. SDP files contain streaming media initialisation parameters and properties. An SDP file
does not deliver media itself but through file association the media stream can be opened in
media players such as QuickTime and VLC. You can also use the SDP file to specify the URI in
your web browser.

Request I-frame
When joining a multicast stream in the middle of a long GOP, requesting an I-frame
will speed up response time, i.e. image display will start sooner.
Request I-frame hold
off
Range: [0…255] frames. Requesting (too) many I-frames may add to latency. To
prevent this, you can specify the distance in frames, starting after the previous
I-frame, before another I-frame is sent upon request.
Scene change detect
Enables the scene detection algorithm. If enabled, the encoder can fully restart a
new GOP with an I-slice and an instantaneous decoding refresh (IDR) picture,
depending on image content.
Scene change detect
period
Sets the minimum time between scene changes in milliseconds. This is a hold-off
mechanism that prevents a scene change for the specified time, starting from the
previous scene change.

Description
Force frame mode
If Force frame mode is enabled on <ManufacturerNames> video encoders, the
H.264 video stream is compressed and sent using entire frames (Frame mode). If
disabled, the stream is compressed and sent using entire frames or the separate
fields (Field mode). Note, however, that the TC620-PID operates with frame mode
only. There is no need to select or clear this check box, therefore.
Deblocking filter
Enables the in-loop deblocking filter in the AVC encoder. H.264 encoding can
handle portions of the video image in blocks of varying sizes which can be
processed independently. The deblocking filter enhances image quality by
smoothing block edges and reducing blocking distortion. Be aware, however, that
applying the filter requires substantial processing power.
Deblocking filter alpha
coefficient
Set the alpha/beta coefficients of the deblocking filter. Entering experimental
values for these coefficients may help you in achieving optimal image quality.

Each I-frame
Data block is added after each I-frame. The interval is
determined by the GOP length, therefore.
Meta data insertion
interval
Range: [100-10000] ms. Sets the (fixed) interval at which meta data is added to the
stream. Activate this parameter by setting Meta data insertion mode (see above) to
Fixed interval.

12.3.5.2 Stream Manager
Video > Encoder # > Advanced > Stream Manager
Balancing network load
Peaks in the network load vary with encoder output. Use the Stream Manager to balance network
load. It can limit the output rate per stream sent to the transmitters. Be warned that setting the
Stream bandwidth limit to a lower value may introduce latency because peaks in the encoder
output will be buffered.
Item
Description
Stream bandwidth limit
Range: [0...100000] kbit/s. Sets the maximum bit rate per stream sent to the
transmitters. This will serve to spread bursts but in its turn may give rise to
latency, e.g. when handling large I-frames.
You are advised to limit the outgoing bit rate per encoder to a maximum of
15 Mbit/s. The total outgoing bit rate of all encoders (including the Live View
encoder), RTSP controlled streams, and SAP streams, should not exceed 25
Mbit/s. See the value for the Total tx bit rate parameter on the Measurements tab
of the Status page.
The Stream bandwidth limit mechanism is disabled when Low latency (see
below) is selected. See also the graphic in the Note on FloodGuard.
Keep-alive interval
Range: [10 … 100000] milliseconds. The frequency for sending keep-alive
messages to the encoder.
Low latency
Raises the output bandwidth limit to allow for peaks in the network load. To be
selected if you need to keep the delay between the input and output of images as
short as possible, for improved tracking with a dome camera for example.
Selecting Low latency disables the Stream bandwidth limit mechanism.
Note on Low Latency mode: This mode may cause packet loss in the network. In this mode,
short bursts of 100 MB data may overflow the input buffer of an Ethernet aggregation switch. As
a rule of thumb, the average load of an Ethernet port should not exceed 40% of its maximum
load (i.e. 40 MB for a 100 MB port).

12.3.6 Meta data insertion
Enabling
All TC620-PID encoders can be configured to include meta data in the video streams they
generate. The insertion of meta data is enabled by setting an interval via the Advanced Settings
of the encoder. A meta data message is added to the stream as a block of data with a fixed
format (see examples below). The messages can contain user data, product info, and status info.
Note: This section provides a general explanation of meta data insertion as implemented in
Siqura products. The unit described in this manual, may or may not feature all of the media (e.g.
audio, contact closure) and encoding formats included below.
User data message
For MPEG-2 and MPEG-4, User data is preceded by the User data header (00 00 01 B2):
0x00

12.3.7 Notes
Note on Differentiated Services: Differentiated Services (DiffServ, or DS) is a method for adding
QoS (Quality of Service) to IP networks. In routed networks, critical network traffic such as video
and audio streams, which require a relatively uninterrupted flow of data, can get blocked due to
other traffic. DiffServ can be used to classify network traffic and give precedence - i.e.
low-latency, guaranteed service - to high-priority traffic, while offering best-effort service to
non-critical traffic such as file transfers or web traffic.
Each stream has a DSCP (Differentiated Services Code Point) field in the IP header. Routers will
identify the network service type in the DSCP field and provide the appropriate level of service.
Low-latency service can be realized, for example, through priority queuing, bandwidth
allocation, or by assigning dedicated routes.
Note on RTP and RTCP: The Real-time Transport Protocol (RTP) is designed for end-to-end
real-time, audio or video data flow transport. It is regarded as the primary standard for
video/audio transport over multicast or unicast network services. RTP does not provide
guaranteed delivery, but sequencing of the data makes it possible to detect missing packets. It
allows the recipient to compensate for breaks in sequence that may occur during the transfer on
an IP network. Error concealment can make the loss of packets unnoticeable.
RTP is usually used in conjunction with the Real-time Transport Control Protocol (RTCP). RTP
carries the media streams. RTCP provides reception quality feedback, participant identification
and synchronization between media streams.
Note on the Session Announcement Protocol (SAP): SAP, defined in RFC 2974 (see RFC 2974 -
http://www.ietf.org/rfc/rfc2974.txt), is a protocol for advertising multicast session information.
A SAP announcer periodically broadcasts announcement packets which include the session
description information of multicast sessions presented by the announcer. SAP uses the Session
Description Protocol (SDP) as the format of the session descriptions. The announcement is
multicast with the same scope as the session it is announcing, ensuring that the recipients of the
announcement are within the scope of the session the announcement describes. SAP listening
applications can listen to the announcements and use the information to construct a guide of all
advertised sessions. This guide can be used to select and start a particular session. The SAP
announcer is not aware of the presence or absence of SAP listeners.
TC620-PID
Page 70
Note on FloodGuard: FloodGuard is a Siqura™ proprietary stream control mechanism that can
be enabled/disabled independently for each video and sampled data transmitter. FloodGuard
throttles the transmitter when it no longer receives control messages from the receiver, thereby
preventing the transmitter from flooding the network.
FloodGuard only works when enabled on both the transmitter and the receiver, and when the
transmitter sends to a unicast address.
When a transmitter is enabled, it opens a control receive port with the port number equal to its
source port number + 1. This port listens for control packets from the destination receiver. When
no FloodGuard packets come in during the time set for the FloodGuard throttle delay, the
receiver is expected to have disappeared (powered off, receiver disabled, network problem, etc.)
and the stream is 'throttled'. In throttled mode the transmitter - in order to contact the intended
receiver (again) - sends empty packets into the network at an interval determined by the
FloodGuard throttle interval parameter. After reception of a valid FloodGuard packet the
transmitter immediately resumes streaming.

12.4 Encoder 2
Video > Encoder 2
12.4.1 Edge recording
Configuring Encoder 2 settings is done in the same way as for Encoder 1. It is important to bear
in mind, however, that edge recording uses video generated by Encoder 2 and that this requires
specific Video bit rate, GOP length, and Bit rate settings.
Important: If you change these settings, edge recording may become impossible.
Warning: Incorrect encoder settings for edge recording
To configure settings for edge recording
1. Select Enable to enable the encoder.
2. On the Profile list, select H.264 - Edge recording.
3. Click Save.
This creates the following settings.
- Video bit rate mode: Constant bit rate
- GOP length: 25
- Bit rate: 1000 kbit/s
These settings are also the out of the box factory-default settings for Encoder 2. If they are no
longer correct just select the H.264 - Edge recording profile to restore the proper settings.

Sensitivity
This setting relates to local detection levels: local change is only detected if its
level exceeds a certain value. The sensitivity setting can be used to eliminate
unwanted ('false') triggering (e.g. caused by background noise or constant local
movement).
Global threshold low
These settings relate to the summed amount of change within fully or partly
unmasked portion(s) of the screen; a value between the two thresholds gives rise
to a corresponding VMD alarm. The level of this alarm can be set (A-N) using
separate Siqura software.

upper and lower thresholds are shown as two white markers. If the bar runs over the highest
marker, it will turn green again and there will be no alarm condition.
VMD detection windows, with mask applied to the left half of the window. The small white blocks
indicate grid elements where change occurred above the sensitivity level. The summed change is
reflected in the bars on the right, the green one (left) not reaching the lower threshold. The red one
(right picture) extending past it, since this threshold is set much lower.
12.7.5 VMD alarm

TC620-PID
Page 84
Note on Advanced VMD Settings: Motion is detected by comparing the current frame with a
reference image (e.g. a previous frame) and calculating the difference between the two. The
value you enter for the Event window size parameter determines how many frames are
evaluated for VMD purposes at a time. Not all frames from the original video stream are used for
VMD. Only 1 divided by the value set for the frame rate divider frames are evaluated.
A VMD event becomes active when, within the Event window, the number of frames with motion
exceeds a configurable value, the Event window high mark. After this, the VMD event will remain
active until the number of frames with motion drops below another configurable value, the Event
window low mark.
VMD Alarm: Event window high/low mark
X = Event window size
Y = Event window high mark
Z = Event window low mark
VMD alarm becomes active when in at least Y out of X frames motion is detected.
VMD alarm becomes inactive when in at least Z out of X frames no motion is detected.

12.9 Tamper Detect
Video > Tamper Detect
12.9.1 Camera movement and scene changes
As a result of tampering, or more accidentally, after cleaning, a camera may no longer cover the
area designated for monitoring. The Tamper Detect function can detect camera position changes
and scene changes such as a blocked camera view, for example. It does so by comparing the
current image to one or more reference images that were captured and stored earlier.
12.9.2 Enable Tamper Detect
Tamper Detect is disabled by default.
To enable Tamper Detect
In the VCA Settings section, select Enable.
The Position Measurement settings are opened.
Important: If no reference images have been stored yet, a BLOCKED OR CHANGED SCENE alarm

12.9.3 Reference images
You can create up to 16 reference images. This enables you to store images captured in different
day/night situations and/or from multiple PTZ preset positions. When the camera moves to a
different preset Tamper Detect tries to match the new scene to the available reference images.

4. Enter a value (in seconds) for the Sampling duration.
This parameter enables you to capture the background of a scene only and have specific
elements such as moving objects filtered out of the image. With a longer time span for the
sampling duration, persons passing in front of the camera, for example, or cars driving on a
highway can be smoothed out to prevent them from triggering a changed scene alarm.
5. Click the Sample reference button.
The current image is sampled.

Tamper Detect compares the current scene with all available reference images. If a match is
found a green crosshair is superimposed on the image in the Feedback view. Information about
the matched image and the match level is displayed under the Feedback view.
The small green circle in the middle of the image indicates the amount of camera movement that
is allowed. A position alarm is raised when the green circle is outside the crosshair centre. For
information about adjusting the amount of allowed camera movement, see Position
Measurement.
If no match is found a BLOCKED OR CHANGED SCENE alarm is raised.

12.9.8 Position measurement
Video > Tamper Detect > Position Measurement
After creating one or more reference images you can configure the Position Measurement
settings to define thresholds for allowed camera movement and image matching.
Item
Description
Enable
Enables Tamper Detect functionality.
Match threshold
The current image and the reference image it is compared with are considered a
match upon reaching the degree of similarity specified here. The lower the
percentage entered for this parameter, the fuzzier the match.
Match hysteresis
This is the margin area where there is either a match or no match, depending on
the preceding match level. If your alarm output frequently alternates between
"true" and "false" you can use this parameter to fine-tune your settings.
Position threshold
Determines the amount of camera movement that is allowed before a position
alarm is raised. Raising this value allows more camera movement. This is
indicated by the increased size of the green circle in the center of the image.
Evaluation rate
The value entered here determines the speed at which the host machine
processes the algorithms underlying the measurements. Higher values take up
more CPU power.
Defaults
Restores the original settings. Does not affect the current activity status of
Tamper Detect - that is, being Enabled or Disabled.

12.9.9 Alarms
Video > Tamper Detect > Configure Alarms
The Configure Alarms section enables you to view the current status of the alarm output and to
set a delay for the activation/deactivation of alarm outputs.
Note: In addition to the status indication in this section, alarms can also be read from the
TC620-PID 's internal Management Information Base (MIB) using appropriate software, or
through Siqura's Open Streaming Architecture (OSA) - that is, the "Siqura Programming
Interface" (API). The TC620-PID includes SNMP support for its image monitor and tamper detect
functions. A trap is sent when bad image quality or camera tampering has been detected and
another one when the situation returns to normal. This support requires a new SNMP MIB, the
OPTC-VCA-MIB, which can be downloaded at www.siqura.com.
Item
Description
Min. event duration
Alarm output delay time: the time span that is to elapse before a continued
change in conditions actually activates/deactivates the alarm output.
Alarm output
True or False. Indication of current status.
Tip: A PTZ camera moving from one preset to the next may trigger an alarm if the scene change
takes too long. Setting an appropriate time for the Min. event duration parameter can delay the
alarm output until the camera has adopted the new position and the alarm condition has ceased.

12.9.9.1 Alarm examples
Original camera position
Camera has moved to the left. Although the current
image still matches Reference 1, the changed
camera position results in a position alarm.
Camera has moved further to the left.
Current image no longer matches any reference image,
resulting in a changed scene alarm.
Camera lens is being spray-painted, resulting in a
blocked scene alarm.

13.2 Make audio connections
Audio > MX Transmitter and MX Receiver Settings, two-way audio
Audio streams
The TC620-PID provides bidirectional audio. The TC620-PID can send three audio streams to
different destinations, multicast or unicast, to an A-80, or any C-/S-series codec with an audio
interface. It can also receive one audio stream from an A-80 or any C-/S-series codec that
features audio.
Highlighted fields
The source address and port number fields are highlighted in green when the enabled receiver
receives a stream from the specified source. The two fields are marked in red when no stream is
received with the receiver enabled and correctly configured.
Two-way audio
The figure above shows the setup for two-way audio on the side of the TC620-PID. The device on
the other side of the connection (with the IP address 172.22.250.131) would need similar
settings, that is - it must hold the IP address of the TC620-PID as the destination and source.
Transmitters and receivers must be enabled in order for streaming to start. Remember to Save
a configuration to make it effective.
SDP download
Use the SDP Download button to download a Session Description Protocol (SDP) file from the
encoder. SDP files contain streaming media initialisation parameters and properties. An SDP file
does not deliver media itself but through file association the media stream can be opened in
media players such as QuickTime and VLC. You can also use the SDP file to specify the URI in
your web browser.
