Basic parameters - Alphatech (en)

VoIP module:
Video for WEB:

• InternetExplorer - (batch JPEG pictures - port 80) is used over and over again repeated http request ADRESA/video.jpg
  

• Mozilla, opera, Firefox … and programme PopUp (UDVguard) - (MJPEG stream - port 80) is used http request ADRESA/video.mjpg (sometimes it is necessary reload than it start up).This video is continuous and has smaller load nets.
  

• Stream video for IP phones:
  

• H.263 - IPDPvrátný and videophone settling over SIP/SDP protocol on standard SIP port and video (also sound) then runs by RTP protocol on ports settle over SIP (usually 9078).
  

Parameters of video:

• JPG pictures creates in camera and for all transport protocol are same
  

• Size (resolution) of video selects in "Setting video" on WEB
  

• Maximum size is given by type USB camera and mostly is 640x480
  

• Stream H.263 knows only CIF resolution (352x288), so that bigger JPEG is cuts and smaller will frame
  

• Frequency (1 5obr./sec) JPG pictures selects in "Setting video" on WEB
  

• Frequency MJPG and Stream H.263 comes from camera, will use every second and result is moves among 7- 12 fig./sec
  

Ports:

• Port 80 for http (WEB pages and JPG (MJPG) video on them)
  

• Port 5060 for SIP
  

• Ports RTP with adverse party reason with over SIP, usually suggests port 7078 for audio and port 9078 for video
