Requirements for IP devices of audio and video input

Intellect software is compatible with IP devices of video and audio input of the following vendors: Axis, Panasonic, Sony, Arecont Vision and others.

Number of IP devices connected to one Server depends on TCP/IP network bandwidth (see Requirements for TCP/IP Network bandwidth section) and functions performed on the basis of these devices.  For instance, virtual memory consumption (for video.run process) increases when VMDA detectors are in use (see Configuring forensic search in an archive section). One camera with configured VMDA detector can use 30-40 Mb ( depending on camera resolution) of virtual memory. At most 2 Gb of virtual memory is allocated for the video.run process. If it’s needed to connect over 40 IP-video cameras with configured VMDA detections to one Server use 64-bits modules (see the Configuring of using 64-bits modules section).

For proper video recording and playing back time that is set on IP camera (if the device supports this setting) is to be the same as system time on the Server.

Specific application features of certain IP devices:

1. To ensure correct sound recording from Axis IP-cameras when AAC audio codec is used, avoid setting the audio stream bit rate at 8 or 12 Kb/s, if the digitizing rate is 8 kHz: the bite rate should be 16, 24, 32, 48 or 64 Kb.
2. To ensure correct sound recording from Sony IP cameras, avoid using G.726 audio codec: use G.711 codec instead.
