repeated http request ADRESA/video.jpg
Mozilla, Opera, Firefox, etc. and program PopUp (UDVguard software) -
(MJPEG stream - Port 80) – it is used http request ADRESA/video.mjpg
(sometimes you need to reload the page before it starts). This video is more
continuous and loads less the network.
Stream video for IP telephones:
H.263 and H.264 is agreed between the IP Bell doorphpne and the videophone
over SIP/SDP protocol on the standard SIP port. The video and sound then run
over RTP protocol on ports agreed over SIP (usually 9078).
Parameters of video:
JPG images are created in the camera and they are the same for all transport
protocols.
Size (resolution) of video can be selected in the menu "Setting video" in the
WEB interface.
The maximum resolution is defined by the used type of the USB camera,
usually it is 640x480.
Stream H.263 knows only CIF resolution (352x288), therefore larger JPEG is
cut and smaller appears with a frame.
Number of JPG images (1-5 images/sec) can be chosen in "Setting video"
menu in the WEB interface.
Number of MJPG and Stream H.263 / H.264 comes from the camera, every
2nd is used and the result is approx. 7-12 images/sec. on H.263 and up to 5
images/sec. on H.264.
Ports:
Port 80 for http (WEB page and JPG (MJPG) video)

for audio and Port 9078 for video
