RTP over UDP Unicast
RTP over UDP Multicast
RTP interleaved in RTSP over HTTP
7
Short Description PC1656 Picolo.net HD4 Handbook
The streaming is controlled by means of the RTSP protocol. Each RTSP session may include:
One encoded video stream from any of the Video Encoders
One encoded audio stream from any of the Audio Encoders
One metadata stream from any of the Event sources
User Authentication and Access Policy
Picolo.net HD4 implements the following user authentication mechanisms to control the access to its resources:
HTTP and RTSP authentication using the "HTTP Digest Authentication" mechanism
WS authentication using the WS-Security “Username Token” mechanism, with the “Password Digest” password
type.
Web Pages through login/password dialog box.
Picolo.net HD4 implements the default access policy recommended by the ONVIF 2.2 Core Specification. The policy
implements four user levels: Administrator, Operator, User, and Anonymous.
Encryption
Picolo.net HD4 implements the following encryption mechanisms:
Web Service messages encryption using TLS 1.0
HTTPS Web Pages encrypted access using TLS 1.0
Compliance
Picolo.net HD4 is an encoder device complying with the version 1.0 of the ONVIF Profile S Specification.
The HD-SDI video inputs of Picolo.net HD4 comply with the Version 1.0 of the HDcctv Alliance standard. The device
has been tested according to the Version 1.1 HDcctv Compliance Certification Standard and has been found to be
in compliance with the Minimum Requirements.
Physical
Picolo.net HD4:
Is packaged in an aluminum enclosure that can be installed on a desktop, on a wall using a baseplate, or on a
DIN-rail using a clip-on baseplate.
Is intended for indoor use exclusively.
Is a fan-less device that supports ambient temperatures up to 55°C or 131°F.
Is 12V-24V DC powered.
Note. Pre-series products, SN00011 up to SN00070, are restricted for use with 12V DC supply!

Mounting Methods
The following mounting methods are available:
Desktop: the product lays down on top of a horizontal flat surface such as a table.
Wall: the product is hooked-up on a baseplate, itself screwed on a vertical flat surface such as a wall.
DIN-rail: the product is hooked-up on a baseplate, itself clipsed on a DIN-rail.

Desktop Mount
Picolo.net HD4 "Desktop"
The out-of-the box product, namely the Picolo.net HD4 "Desktop", is ready for a desktop usage. The baseplate and
the DIN-rail clip may be discarded.
The enclosure is designed in such a way that its bottom side faces the table. The four embossings on the bottom side
of the plastic caps act as anti-skid feet, and avoid direct contact between metallic parts and the table.
Wall Mount
The Picolo.net HD4 "Desktop" is used together with the baseplate. The DIN-rail clip may be discarded.
First of all, the baseplate has to be attached to the wall using appropriate fixation methods. Therefore it is equipped
with four oblong openings allowing easy installation and alignment. The openings dimensions are 4 mm x 12 mm
(0.16" x 0.47").
The enclosure is then hooked upon the baseplate by first inserting the long enclosure brackets, then the short brackets.
The four embossings on the bottom side of the plastic caps act as anti-skid feet, and prevent any movement of the
enclosure once hooked-up on the baseplate.

Mechanical Specification PC1656 Picolo.net HD4 Handbook
The enclosure and the baseplate are designed in such a way that the enclosure can be mounted on a vertical flat
surface with three possible orientations:
Horizontal: the BNC video connectors are facing rightwards and the Euresys logo is horizontal.
Vertical Downwards: the BNC video connectors and the Euresys logo are oriented downwards.
Vertical Upwards: the BNC video connectors and the Euresys logo are oriented upwards.
Note. BNC video connectors facing leftwards is not allowed.

DIN-Rail Mount
To mount Picolo.net HD4 on a DIN rail, the DIN-rail clip must be installed on the back side of the baseplate, and the
enclosure must be hooked-up on the baseplate like for the wall-mount usage.
Assuming that the DIN rail is always horizontal, the DIN-rail clip must be oriented according to the desired orientations
for the BNC connectors.
DIN-rail clip orientation, for BNC video connectors facing upwards or downwards
DIN-rail clip orientation, for BNC video connectors facing rightwards
(BNC video connectors facing leftwards is not allowed)
The DIN-rail clip is equipped with a lever that facilitates the removal from the DIN rail.

Relay Output port schematic
The contact remains in the OPEN state during the board initialization procedure.
In the CLOSED state, the output port exhibit a voltage drop across its pins. Typical voltage drops for current values
of 1, 10 and 100 mA are shown in the following table:
Operating the relay output with load currents below 1 mA is not recommended since it exhibit a large equivalent
resistance!

Circuit Diagram
Power Supply
Operating the relay output circuit requires an external power source.
The power source can be either DC or AC since the relay output port is capable of switching current of both polarities.
The recommended voltage rating ranges from 5V up to 24V for DC supply and from 5V
RMS
up to 15V
RMS
for AC supply.
Load
The load impedance must be essentially resistive.
If the load is capacitive, it is necessary to insert a series resistor to prevent against excessive currents when the relay
output enters the CLOSED state.
If the load is inductive, it is necessary to insert a series resistor to prevent against excessive voltage spikes when
the relay output changes of state.
The recommended current rating ranges from 1 mA to 100 mA for the whole operating temperature range.
As shown on the following table, the range of allowed load resistance values depends on the selected supply voltage
and the load current limits.
