DW-CP16 Compressor™ User Manual
Digital Watchdog® 15 www.digital-watchdog.com
Connecting Digital Input / Output Devices
Depending on your surveillance needs, you may connect digital input / output devices to your
encoder.
Digital Input (DI) devices can be used to notify the encoder of an activity in the camera on the
encoder site. DI can be triggers of events. For example, you can connect a “panic button” to the
encoder; as such when the panic button is pressed, the alarm signal will be sent through the
encoder. Other common DI device applications are emergency button, smoke detector, passive
infrared sensor, etc.
Digital Output (DO) devices are external devices that are activated by the encoder upon an
event within the encoder (e.g. video connection is lost, etc.) or triggered by motion in the
camera site among others. For example, you can connect an “alarm horn” to the encoder; as
such when an event occurs on the camera side (e.g. detected intruder), the alarm horn will
sound. Other common DO device applications are motion-triggered lights, electric fence,
magnetic door locks, etc.
The digital input and output pins of the Compressor are configurable. Either a digital input or
digital output device can be connected to a particular DIO pin. Once connected, the pin must
be defined through the Web Configurator. The Compressor supports 16 DIO ports.
Four (4) DIO ports share the same terminal block with four (4) audio input ports. See samples
below:
1. Loosen the screw of the pin and insert the wire through the pin slot.

NOTE: For every digital output device, a wire must also be mapped to the 12V pin. For
every digital input device, a wire must also be mapped to the GND pin. The GND and 12V
pins may be mapped with more than one device.
3. Tighten the screws to secure the wires within the pin slot.
4. Connect the terminal block to the corresponding DIO connector of the encoder.
5. Configure the DIO ports in the Compressor’s Web Configurator.

Accessing the Encoder
Configure the IP Addresses
In order to communicate with the encoder from your PC, both the encoder and the PC have to
be in the same network segment. In most cases, it means that they both should have very similar
IP addresses, where only the last number of the IP address is different from each other. There
are 2 different approaches to IP Address management in Local Area Networks – by DHCP Server
or Manually.
Using DHCP server to assign IP addresses:
If you have connected the computer and the encoder into a network that has a DHCP server
running, you do not need to configure the IP addresses. In such case, the encoder will
immediately be ready for the access from the PC. The encoder will be assigned all its network
settings automatically to follow the current network’s settings.
The quickest way to discover the encoders in the network is to use the UPnP function supported
by the Compressor. Press the “Network” icon on your PC, and all the encoders on the local area
network will be discovered by Windows.
Double-click on the encoder model to launch the Compressor’s web viewer automatically.
DW-CP16
DW-CP16 Compressor™ User Manual
Digital Watchdog® 22 www.digital-watchdog.com
You may also discover and access your Compressor by using the IP Utility tool. The IP Utility is a
light software tool that can discover the encoders, show their basic information such as IP and
MAC addresses, serial numbers, firmware versions, etc., and allows quick configuration of
multiple devices simultaneously.
The IP Utility can be downloaded for free from http://www.digital-watchdog.com
With just one click, you can launch the IP Utility:
You can locate the encoder model in the list. Click on the IP address to automatically launch the
Compressor’s web viewer.
Compressor’s Default IP Address:
If there is no DHCP server in the given network, you may have to assign the IP addresses to the
encoder manually.
When the encoder is plugged into network and it does not detect any DHCP services, it will
automatically assign itself a default IP address:
DW-CP16 Compressor™ User Manual
Digital Watchdog® 23 www.digital-watchdog.com
192.168.0.100
The default port number would be 80. In order to access that encoder, the IP address of the PC
has to be configured to match the network segment of the encoder.
Manually adjust the IP address of the PC:
1 2 3
4
DW-CP16 Compressor™ User Manual
Digital Watchdog® 24 www.digital-watchdog.com
DW-CP16 Compressor™ User Manual
Digital Watchdog® 25 www.digital-watchdog.com
Manually adjust the IP addresses of multiple encoders:
If there are more than 1 encoder in the same local area network and there is no DHCP server, all
of the encoders would then have the initial IP address of 192.168.0.100. The easiest way to assign
encoders the IP addresses is by using the IP Utility:
With the procedure shown above, all the encoders will have unique IP addresses, starting from
192.168.0.101. In case there are 20 encoders selected, the last one of the encoders would have
the IP 192.168.0.120.
Press the “Refresh” button of the IP Utility to see the list of encoders with their new IP addresses.
Please note that it is also possible to change the IP addresses manually by using the Web browser,
plugging in one encoder at a time, and changing its IP address using the Web browser.

Serial Setting
The Serial Setting allows you to set the serial port configurations of the encoder. There are two
serial ports that can be shared by the channels. The serial port on the connected devices must
be the same as the configurations of the serial port on the encoder.
Serial Port Control: Select the serial port control that matches with the serial port configured
on the PT device. This function is equivalent to the DIP switch of the PT device.
Serial Port Baud Rate: Select the baud rate that matches with the baud rate set on the PT
device.
PTZ Vendor/Protocol: The Compressor fully support the URL Command, a high level PT
command set. However, in case the devices will be used with devices from third party vendors
that only support Serial Hex Command (low level PT command set), users must select the PTZ
Vendor/Protocol to use. Otherwise, leave the default settings.
Video Channel’s PTZ Address
The Video Channel’s PTZ Address section allows the user to enable the serial port and assign
the PTZ address of a video channel. All video channels share two (2) serial ports therefore the
port number and PTZ address for each channel must be defined on this section.

Multicast Setting
Multicast is an Internet protocol where a data stream is
sent only once and shared to requesting devices to save
network bandwidth. To use this, network devices, such as routers and switches, should support
IP multicast.
The Multicast IP, port, and TTL are set to their default values but can be adjusted as needed.
Parameters Description
Configuration setting is based
on channel 1
Select to configure Channel 1 multicast settings and use these as a pattern to
base the succeeding channel settings.
Manual
Select to manually configure the settings of all channels.
Channel (number) Refers to the video channel.
Stream 1 Refers to the video stream 1 of the corresponding channel.
Stream 2 Refers to the video stream 2 of the corresponding channel.
Audio Refers to the audio stream of the corresponding channel.
Multicast IP Enter the multicast IP of the corresponding stream.
Network Port Enter the assigned port of the corresponding stream.
Multicast TTL
Enter the multicast TTL (time-to-live) of the corresponding stream. This value
determines the time span (in seconds) when the packet is retained in the
DW-CP16 Compressor™ User Manual

network. When the time expires and no request is received, the packet is
discarded.
By Request
When checked, the video or audio stream
will be streamed only to a
particular receiver when that receiver sends a request or in the
case of an NVR, selects to view or record the channel. If unchecked,
the video or audio stream will constantly be streamed to the
network whether there are devices viewing the channel or not.
To save on network bandwidth, it is recommended to check this function.

HTTPS
HTTPS protocol allows creating a secure channel over an
insecure network to protect the data sent between the
device and its counterpart. Two things are required for a secure communication – encrypted
data, and verified counterpart of the communication. To make sure that the messages are
being sent and received from true counterpart, the certificate is needed.
There are two methods to create certificates – Certificate Signing Request (CSR) and Self-Signed
Certificate.
• Certificate Signing Request (CSR): User uses a signed certificate issued by trusted
Certification Authority (CA).

SNMP Setting
The SNMP Setting submenu displays the SNMP
configuration page.
SNMP provides an easy way to manage network devices. The main features are:
1. Monitoring device uptime
2. System detail description. (Ex: model name, model description and firmware version.)
3. Collect interface information. (Ex: MAC address, interface speed, local port.)
4. Measuring network interface throughput.
To use SNMP, just enable SNMP function in the device (SNMP agents) and run SNMP
management software in server (NMS: Network Management Station) to connect to the devices.
The SNMP agent supports versions V1, V2 and V3. SNMP V1 is the initial implementation of SNMP.
SNMP V2 is proposed to enhance the performance of management, such as the communication
of server and devices, the confirmation of information delivery and receipt. Primary additions in
SNMP V3 concern security and remote configuration enhancements.
DW-CP16 Compressor™ User Manual
Digital Watchdog® 55 www.digital-watchdog.com
SNMP V1/V2 uses the “Community” name as password to authenticate identity. “Read
Community” is the password for server to get information from devices. “Write Community” is
the password for server to edit values on devices. The default is “public” for Read Community
and “write” for Write Community. Of course, you can set any other password as your read/write
community.
You can enable V1, V2 or both. Click Apply after setup is complete.
SNMP V3 uses account/password for authentication. “Security Name” is the account name to be
used with your “Password”. The default security name is “public” and the password must be at
least 8 characters long. You also can set any other security name or password.
Click “Apply” after setup is complete. You may now install and run the SNMP management
software on the computer server.
SNMP Trap Usage:
SNMP traps enable notifications from devices. Devices may send message to the management
server whenever significant events occur such as cold start, warm start and authentication failure.
The manager will get the information immediately and take action if necessary.
Cold start means device reboot by power disconnection. Warm start means device reboot by
firmware without power disconnection. If there other parties attempt to connect to the device
DW-CP16 Compressor™ User Manual
Digital Watchdog® 56 www.digital-watchdog.com
with wrong security password under SNMP V1, V2 or V3 setting, the device will send an
authentication failure message to the management server.
To enable SNMP Trap function in the device, type the IP address of the computer running the
SNMP management software and type trap community as password to allow server to get trap
message from device (Default is public). Select available traps and click “Apply”.
Device’s SNMP offers following information:
Group
Description
System Provide general information about the managed device.
Ex: system description, system name.
Interface Provide general information from the physical interfaces.
Ex: interface speed, MAC address.
Address
Translation

IP Settings
The IP Settings menu provides the options to define how
the device would obtain its IP address and which DNS server it will connect to.
Connection Type
The Connection Type submenu allows defining the method
of obtaining the IP address of the device. By default, the device is in Dynamic IP Address mode
and attempts to get the IP address from a DHCP server. If such attempt fails, the device will
automatically assign itself an IP address, listed under Static IP Address.
Host Name is used to identify the device by a DHCP server. In some networks with very strict
security policy, it is required that all the network devices should have their host name, and when
the devices attempt to access the network by requesting an IP address from a DHCP server, the
DHCP server would check if the host name is among the allowed devices. On this page, it is
possible to edit the Host Name and enable or disable the use of host name.
If necessary, you can change the connection type to Static IP Address mode and manually modify
the IP Address, Subnet Mask and Gateway.

DW-CP16 Compressor™ User Manual
Digital Watchdog® 65 www.digital-watchdog.com
Usually, Stream-1 is configured to be high quality video with maximum resolution and frame rate
for recording purposes. Stream-2 is usually a moderate quality stream for live view purposes to
reduce VMS computing power during video decoding of multiple channels.
DW-CP16 Compressor™ User Manual
Digital Watchdog® 66 www.digital-watchdog.com
Compression
The Compression section allows the user to define the compression settings of stream 1 and
stream 2. The purpose of compression is to reduce the bandwidth and VMS storage consumption.
Parameters Description
Encoder Type
There are two encoder types available: H.264 (Hig
h Profile) and
MJPEG.
H.264 Profile
The H.264 Profile defines the video compression scheme: High
Profile, Main Profile, and Baseline. These schemes vary from least
compressed, Baseline, to most compressed, High Profile. By default,
the H.264 Profile is High Profile
, which provides the most
compression with the best video quality, but requires more
computing power.
In order to get the same video quality, you can select a higher bit rate
with lower compression; this is the same as having a lower bit rate
with a High Profile. For example, a video on High Profile with 2M bit
rate will have the same video quality as a video with Baseline Profile
at 3.5M bit rate.
Resolution
The default resolution setting of the device may not necessarily be
the maximum resolution of the camera. If the user wants to use the
maximum resolution, it is possible to do it here. The maximum
possible resolution of the stream 2 will be smaller than stream 1.
Frame Rate Defines the amount of frames per second.
Video Bit Rate Mode
(H.264 Only)
Under Constant Bit Rate mode (CBR), the device keeps the stable
bitrate regardless of the complexity of the scene. Video quality may
vary if the bit rate value is set too low. It is easier to do storage and
network bandwidth consumption estimatio
ns under this mode
compared to Variable Bit Rate mode.
DW-CP16 Compressor™ User Manual
Digital Watchdog® 67 www.digital-watchdog.com
Under Variable Bit Rate mode (VBR), the device will keep the video
quality stable while the bit rate goes up or down, depending on the
complexity of the scene.
Video Max Bit Rate
(H.264 Only)
Defines the upper limit of the bitrate (if CBR mode is selected). The
bitrate will be floating slightly under that limit.
If the Video Max Bit Rate is chosen as
Unlimited, the Video Bit Rate
selection box will define the bit rate
level.
Video Bit Rate
(H.264 Only)
Under CBR mode, when Video Max Bit Rate is chosen Unlimited, the
user can define the AVERAGE bit rate. This mode allows the most
accurate storage estimations, however, while planning the
bandwidth, please consider the occasional peaks of bit rate.
Quality H.264 Compression:
Under VBR mode, the bit rate will
be floating while the video quality
will be stable. The user can choose
either High, Medium or Low
quality. The higher the quality level, the more bit rate the device will
use to achieve the target quality.
MJPEG Compression:
The user can define the quality from 1 to 100. The default MJPEG
quality is 60. The higher the quality level, the more bit rate the device
will use to achieve the target quality.
GOP 1 I-frame
(H.264 Only)
The GOP length is the occurrence rate of I-frames. By default, there
is one I-frame per second. For example, in case of 30fps, there will be
1 I-frame and 29 P-frames. When the GOP is changed to “1 I-frame
per 5 seconds”, then there will be one I-frame, followed by 149 Pframes. In case of a static scene, long GOP can reduce bandwidth and
storage consumption.

Motion Detection
The Motion Detection section allows the user to configure the video motion detection system
of the device. Motion detection regions are based on Stream 1. By default, all the regions are
disabled. To start, select the channel from the drop-down box to set its motion detection.
Click Setup to adjust the motion detection regions or its parameters.
NOTE: Microsoft Internet Explorer browser is required to configure the motion detection
regions.
There are three independently configurable motion detection regions. Each motion detection
has 6 configuration parameters:
Enabled or disabled
Location of the region
Size of the region
Sensitivity
Trigger threshold
Trigger interval
DW-CP16 Compressor™ User Manual
Digital Watchdog® 70 www.digital-watchdog.com
Enabled or Disabled
Each of the motion detection regions can be enabled or disabled individually.
Location of the region
You can move the motion detection region anywhere on the field
of view by dragging the top of the motion detection rectangle. The
motion detection regions may even be overlapping if you like.
Size of the region
By dragging the lower right corner of the motion detection region
you can change the size of the region. The maximum size of the
region can be as big as the whole screen.
Sensitivity
In order to avoid false alarms, we might want the device be able to ignore small motion. The
higher the sensitivity level, the smaller shift of the object is needed to trigger the alarm. For
example, if the object has moved for about 1-3 pixels during two video frames, then such small
motion will be discarded by device if the sensitivity is low. You can think of sensitivity level as a
reversed speed limit – the smaller is the sensitivity, the faster are the objects allowed to move
without being detected.
DW-CP16 Compressor™ User Manual
Digital Watchdog® 71 www.digital-watchdog.com
The biggest challenge of motion detection configuration is to find the settings that do not
produce false alarms and at the same time do not miss any actual intrusions. The rule of thumb
is: the sensitivity should be as high as possible while not producing false alarms. The default
sensitivity level of the devices is 70 (on a scale of 0-100) and it is a good setting for most standard
cases.
Trigger threshold
The blue graph on the right side of the
image shows how many percent of
pixels within the motion detection
region were considered as “currently
in motion”. The activity panel itself is
a timeline. You may notice that at
certain moment the tallest bars in the
activity graph reached about 25% – it
means 25% of this motion detection
area were filled with moving pixels at that moment.
What if the object is really small but moves rather fast (gets triggered by the current sensitivity
level)? For example, we want to detect people but not the cat walking in the room. Although
both people and cat may move with the speed that will trigger motion, they have different size
of triggered pixels. Since we want to have a real alarm in case of human or vehicle passing by
while ignoring birds, cats, etc., we need a filter that can define how many percent of triggered
pixels will be considered as a real alarm. This parameter is called trigger threshold. The default
value of trigger threshold is 10%. It means, only the objects that are bigger than 10% of the
motion detection region size and move faster than allowed by sensitivity level (70) will produce
actual alarm.
DW-CP16 Compressor™ User Manual
Digital Watchdog® 72 www.digital-watchdog.com
How to choose the most optimal trigger threshold level? The rule of thumb, keep the trigger
threshold as small as possible while not causing false alarms by the moving objects that are
not humans or vehicles.
In order to understand all of the above even better, please refer to the table below containing
four possible combinations of settings using sensitivity level and trigger threshold percentage.
The objects listed in each cell will trigger an alarm under given settings:
Low threshold (0-5%) High threshold (5-100%)
Low sensitivity
(0-65)
Big and fast
Small and fast
Big and fast
High sensitivity
(65-100)
Big and fast
Big and slow
Small and fast
Small and slow
Big and fast
Big and slow
DW-CP16 Compressor™ User Manual
Digital Watchdog® 73 www.digital-watchdog.com
The device’s default sensitivity is 70 and threshold is 10%. By these default values, only the
rabbit and the turtle would trigger an alarm while the butterfly and the snail would be ignored
by the motion detection system.
Important: Changing the size of the motion detection region has an impact on the threshold –
the bigger is the size of the motion detection region, the smaller should the threshold value be
if you want the same objects to trigger motion.
DW-CP16 Compressor™ User Manual
Digital Watchdog® 74 www.digital-watchdog.com
Trigger interval
Trigger interval is the time period from the beginning of the triggered event during which all
other motion activities are ignored by the device. This is designed to avoid needless repetitive
reporting of the same intrusion. Trigger interval 20 seconds means that when the even happens,
the device will take a one-time action and ignore the continuing activity in the motion region for
20 seconds. When 20 seconds are over, the device will produce a new alarm if there are still
action in the motion detection region.
Profile of Motion Detection
Think of them as Profile 1 (Runtime MD Profile) and Profile 2
(Event MD Profile). You can configure two independent groups
of Motion Detection regions with 3 regions per group. Normally, the Profile 1 (Runtime MD
Profile) is used as an active profile. It is possible to switch to Profile 2 by using the Event Handler
system. For example, you might want to have different motion detection parameters for day and
night time.

Privacy Mask
The Privacy Mask section allows the user to mask sensitive areas of the video that should not be
captured by the device, such as a manager’s computer screen or bathroom entrance.
It is possible to set up to 4 regions of privacy masks. The adjustment of the privacy mask region
can be done when the region is checked under the Setup column.
NOTE: PTZ and zoom cameras may yield inaccurate results when used with this feature.
DW-CP16 Compressor™ User Manual

You may resize and drag the region the same
way as the motion detection regions: upper
bar that contains the number of the region
can be used for dragging the region across the
video while the white box at the right lower
corner of the mask can be used for resizing
the region.
There are 4 pre-defined color options for privacy masks. To use any other colors, use URL
commands to set up the privacy mask. Refer to the Guide that explains the use of URL commands.
For PTZ device models, the privacy mask is dynamic. Thus, when the device pans away from the
mask’s position, the region remains covered for privacy. You can select one color for all 4 privacy
masks.
Please note that the Privacy Masks will take effect for both Stream 1 and Stream 2.

Event
This section describes how to setup the Event Handler, which de als with how the Compressor
responds to events. Eac h I P devic e can have a max i mum of 1 0 Eve nt Rul es. E ach rule includ es
one single trigger, and one or many resp onses. Several types of responses are avail able. And
there are multiple external servers for the device to interact with.
When setting up Event Handler, there are four types of settings. Event Server, Event Configuration,
Event Rules and Manual Event
Click the item before Event to expand the list.
Event Server
Event server define whom the device may interact with. They can be other servers or devices on
the network, or even the device itself. Event Configuration sets up a list of wh at to tel l th e ot her
party during interaction. Event list lays down the rules and conditions about when to initiate which
responses from which tr iggers. The options available for Event rules are selected from the

SMTP Server
SMTP servers can send email upon request from the IP device. The email can be a simple subject
and text email, or attached with snapshot / video. You may setup two SMTP servers. The device
will first attempt to send the message via the Primary email SMTP server. If the first attempt fails
(after the Max connecting time), then the device will attempt to send via the secondary SMTP
server. If the device sends email successfully via the primary SMTP server, then it will not use the
secondary SMTP server.
To setup SMTP servers, make sure to enable the SMTP account and choose the proper
Authentication Type. There are many types available. The default is Login. We recommend you
to use Auto Detection. Available authentication types include: Auto Detection, None, Login,
Plain, Cram MD5, Digest MD5 and PoP Relay. Please also enter the User Name, Password, the
Email Address displayed as sender (can be different than the user name), Network (SMTP server)
Address, Network (SMTP server) Port number and Max Connection Time before timeout (in
seconds).

HTTP Server
HTTP CGI servers are programs that run on web sites or devices. They can be custom
programmed to perform a large variety of actions based upon the input. You can define which CGI
server to connect to here, and the user / password required to log into the target server. The actual
message / command is s etup in the Notificati on messages / URL com mands section. Yo u may
define two separate CGI servers.
IP devices are also CG I servers . This means tha t IP devices c an now issue c ommands to eac h
other, which creates endless possibilities for highly coordinated response. The IP device can also
give a loopback command to itself, in effect changing almost all possible settings dynamically.
For example, device A is a fixed device that looks at a corridor leading to the main hall. It has a
motion detection window located near the point where the corridor arrives at the large hall.
Device B is a PTZ device located in the hall, which is usually left on auto-tour patrol. When motion
activity in the motion detection region triggers MD1 in Device A, this then in turn activates an
event rule in Device A that gives out a command to Device B. Device B would then swivel to the
preset point where the corridor leads into the entrance and switch to higher bit rate to
temporarily provide clearer image. After the event ends, Device B will go back to its normal
routine in lower bit rate.
To setup HTTP servers, make sure to enable the HTTP server, enter the user name, the user
password, Network (HTTP Server) address, Network (HTTP Server) port number and Max
connection time before timeout (in seconds).

Event Configuration
Event configuration are t he responses to be per formed when an event is triggered. For most
types of responses, you can create several different responses, then mix and match in event rules.
The configurable responses are classified as Digital I/O ports, Notification messages, Upload
Video/Snapshot and Audio and Send URL Commands.
Digital I/O Ports
Digital Input (DI) device is a trigger device like a switch or sensor (e.g. “panic button”), which
when triggered, notifies the device to perform specific actions or the Digital Output (DO) device
to respond. DO’s can be alarms or lights, etc.
The Digital I/O Ports page displays the number of available DIO ports on the device.
DW-CP16 Compressor™ User Manual
Digital Watchdog® 88 www.digital-watchdog.com
These DIO ports can be configured to either DI or DO on the I/O column. Check the channel
number box on the Channel column to assign a video channel for that port.
DI: To configure the digital input device, define the active level and trigger interval of the DI.
The default Active Level is “0”, which means the DI device remains inactive unless triggered. A
good example is a “panic button”, which always stays in inactive mode “0” until the button is
pressed; when the button is pressed, its active level becomes “1” which means the DI is
triggered. Active level “1” returns back to “0” (inactive mode) after the specified Interval. The
Interval is the duration of time when the trigger remains in active mode which is also the
minimum time interval between the previous trigger and the next. For example, if the interval
is set to “5 seconds”, the DI will not respond if the “panic button” is pressed within 3 seconds
after the previous trigger. To issue another trigger, click the button after 5 seconds from the
previous trigger.
DO: To configure the digital output device, define the active level and response interval. The
default Active Level is “1”, which means the DO will turn to active mode and respond once
triggered. The duration of its response will last according to the set Interval. A good example is
an alarm siren, wherein the siren will start sounding only when it is triggered by an event or
another device like a DI. The siren will stop sounding once the set interval time elapsed.
A DO port is automatically associated to every video channel thus the channel numbers on
Channel are automatically checked for the port that is set as DO.
After changing any of the items above, click Apply to save the changes. The Reset button undoes
the changes that had just been made but not yet applied or saved.
By default, the Active Level of each port is “0”, which means the DI/DO device will remain
inactive unless triggered. The duration of its response will last according to the set Interval.
After changing any of the items above, click Apply to save the changes. The Reset button undoes
the changes that had just been made but not yet applied or saved.

Notification Message
Notification messages may be sent to either an email or a HTTP CGI server. If sent to a CGI server,
it works the same as an URL command, but it does not allow a second message at end of event.
You may configure up to three preset massages. You can configure a message, but disable it. This
will allow you to keep the settings without using it, which will be useful in testing and
troubleshooting.
To setup Notification Mes sages, make sur e to enable the m essage and determi ne what type of
message to send (HT TP CGI or e mail). If you ar e sending t o CGI serv er, you ne ed to enter the

Send URL commands
URL commands can be se nt to HTTP CGI servers upon event. T his provides the possibility of
highly intelligent resp onse upon ev ent. IP d evic es and many other dev ices also have embedde d
CGI servers that may be controlled.
When Event Handler sends an URL command, it will send one set of command when the event is
trigged, and another as the event becomes inactive. Depending on the CGI design, the URL
commands may be able to be stringed together, and multiple commands may be issued in a single
line.
An example would be when the access control device at the entrance detects an entry, this
device provides a DI signal to the PTZ device, and triggers an event. This event then sends a
loopback command to the PTZ Device itself (by setting its own IP as the HTTP CGI server). The
PTZ Device then moves to a preset location, stays until the event is over, and then moves back
to another location. At the same time it moves to the pre-set location, it increases the bitrate
from 1M to 3M, and the frame rate from 4 fps to 8 fps. The bitrate / fps changes are reverted at
the end of event.

Event List
You may define a maximum of 10 Event rules, which will be shown in abbreviated form in the
Event List panel. It will display under each Event ID, the days of the week it will be active, the
start time and duration of the active period, the type of the source of trigger, and the actions
used in the response. If the row is grayed out, this means the rule is currently not enabled and
stays inactive.
For device models with multiple video channels, select first the video channel to configure from
the channel box.
You may start creating a new event by clicking the event ID number in the list, for example “2”.
There are several parts to the Event rule:
When is It Active?
You may choose to enable the rule or not. The settings will be kept in internal memory even if the
event rule is disabled. Select the days in a weekly cycle in which this rule and schedule is active.
Determine the start time and duration of the active p eriod. For example, a rule that l ets motion
detection trigger snapshot uploads to FTP would only take place after 19:00 each day for 12 hours.
Outside of this time the rule will not be active.
DW-CP16 Compressor™ User Manual
Digital Watchdog® 97 www.digital-watchdog.com
In the example below, the event handler rule is active 24 hours a day, 7 days a week.
How is It Triggered?
Events may be triggered b y one of the s everal so urces. In the ex ample b elow, Motio n Detectio n
region 1 is used as the event trigger.
You may also ask the event to be repeatedly triggered during this scheduled time. The interval is
determined in minutes. You may use this with email / FTP upload to take snapshots at regular
intervals.
Scheduler: The trigger occurs on the specified time. Set the frequency of the occurrence in Occur
Every (minutes).
DIs: The device is triggered by a digital input.
Motion: You may trigger the event if one or many Motion Det ection regions encounter a moti on
trigger. Trigger from any of them w ill i nitiate t he event . The dura tion of eve nt w ill be the s ame as
the MD trigger length, or the Trigger interval time, defined in the Motion Detection section on Video
Adjust page.
Video Loss: This eve nt is triggered when the analo g video input is disconnec ted, whic h makes
the video status as “lost”. The video status returns to “normal” when the device receives the analog
video signal. A common scenario is for the encoder to send an email to the adminstrator when the
video signal is lost, an d activate the DO signal to a larm that persists until the anal og signal is
restored.
DW-CP16 Compressor™ User Manual
Digital Watchdog® 98 www.digital-watchdog.com
Video Recovery: This event is triggered when the analog video input is detected by the encoder.
A common scenario is for the encoder to activate a DO signal such as a light to indicate that video
is being viewed.
