2) Request the camera’s data format via DESCRIBE. The camera will respond with two SDP
parameter sets of the H.264 stream (SPS/PPS) with different Payload types (97 and 96), and the
method of forming RTP data packets and synchronization (90 KHz timer).
3) Specify via SETUP the client ports for receiving the video stream. The client needs to send
two SETUP's corresponding to two parameter sets. For example, for RTP/UDP, ports 1500-1501 for
the first parameter set with trackID=2; port 1502-1503 for the second parameter set with trackID=1.
For RTP/TCP, interleaved channels 0-1 and 2-3 will be assigned to them.
4) Request PLAY to start the RTP video stream.
5) Receive and decode H.264 video frames packed into fragmented RTP packets that are
transmitted via UDP, or optionally over TCP, by the camera. RTP packets sent between two sensors
can be identified by RTP Payload types (96 ands 97).
6) At least every 5 seconds of the RTP streaming send RTCP feedback packets. If the camera
does not receive any RTCP packets over a 10 second period, the session will be terminated.
Optionally, the AV3135 camera can reset the current RTP/RTSP session during day/night sensor switching.
In response, the client has an option to restart a new RTP/RTSP stream session upon detecting the RESET.
This option is enabled via camera's webpage or by sending the following HTTP command:
http://camera_IP/setreg?page=3&reg=185&val=2 (bit1=1 to enable; 0 to disable)
Basic Camera Control Parameters
The camera parameters can be accessed via the HTTP requests of the following format:
http://ip_address/set?parameter=value
http://ip_address/get?parameter
Examples:
http://192.168.0.36/set?brightness=15
http://192.168.0.36/get?brightness
The following parameter requests are supported via HTTP protocol by Arecont Vision cameras:
 brightness – image brightness (valid values are from -50 to 50)
 sharpness – image sharpening(valid values are from 0 to 4)
 saturation – color saturation (valid values from 0 to 6)
 blue - blue tint adjustment (valid values from -10 to +10)
 red - red tint adjustment (valid values from -10 to +10)
 illum – illumination setting for auto white balance (valid values are auto, indoor, outdoor, mix)
