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 for video signal transferring 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 smart video detection tools 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. Enable 64-bit modules if more than 25 Tracker objects are to be used on one Server with video resolution higher than 800x600 (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.
