Bandwidth Efficiency

Bandwidth efficiency has been improved for American Dynamics IP SpeedDome cameras running

firmware version 2.0 or later.

The VideoEdge NVR will use an algorithm to control video quality according to the camera

firmware version. If version is less than 2.0, the video quality will be altered by changing cameras

quality value. If version is 2.0 or later, the video quality will be altered by changing the camera’s

bitrate value. The conversion from quality to bitrate is:

Note

Since the NVR uses CBR to control bitrate, the bandwidth of H.264 and MPEG4 are the same.

This handler does not support VBR.

Limitations

• Only one audio stream (G711aulaw or G711mulaw) can be used at one time

• Dual video streaming supports H.264/MJPEG and MPEG4/MJPEG, but does not support

H.264/MPEG4.

• No PCM audio stream

• Unable to add an IP SpeedDome if it is beyond the IP broadcast range of the NVR

• If Auto Flip is disabled, then the amount of distance of tilt down will be larger when it is close to -

90 degrees than other positions.

• If Auto Flip is enabled, then the tilt down operation in NVR will lock the motor which make auto

flip failure because the tilt down in NVR is not continues (e.g. moveBy) and the moving amount

of distance is very tiny.

• Camera digital PTZ is not supported in this release. So it is not implemented normalization for

digital PTZ part.

• In H.264 single stream, the maximum frame rate is 20fps @ D1 resolution @ quality 70.
