4.1 Electric Parameters
4.2 Mechanical Measurements
The covers of all the Door Entry System covers are IP44 to protect against water intrusion.
4.3 Video Parameters
Video for WEB
Internet Explorer - (series of JPEG pictures-Port 80) uses constantly repeated http request
address/video.jpg.
Mozilla, Opera, Firefox (a program PopUp, UDVguard) – (MJPEG stream – Port80) uses
http request address/video.mjpg (sometimes it is necessary to reload before it starts running
properly). These browsers are preferable to Internet Explorer because the video viewing is
smoother and has less impact on the network load.
Streaming video for IP phones
 H.263 formatting is set automatically between the Door Entry System and the
videophone via a SIP/SDP protocol on a standard SIP port and video (and sound)
which then runs via RTP protocol on ports agreed via SIP (usually 9078).
Video parameters
 JPG pictures are created in the camera and for all transmitting protocols are the
same.
 The size (resolution) of video is selected in “Video setting” on the WEB.
 Maximum size depends on the USB camera type but is usually 640x480.
