VideoEdge NVR 4.1 Release Notes

8200-2735-07 D0

Known Limitations and Issues

Video Loss on NVR

Expectations for video loss are dependent on two conditions:

 The throughput of the source device (e.g. If a camera is only outputting 20 fps, then we

cannot expect the NVR to receive 30 fps).

 Network topology (e.g. The capabilities of routing appliances vary and may introduce an I/O

buffering issue that would cause the loss of video packets).

Camera List with Audio and/or Dry Contact Properties

In the victor Client, it may take considerable longer time to get the camera list from a NVR that

has devices with audio and/or dry contacts setting enabled versus a NVR that has devices with

audio and/or dry contacts disabled.

Camera Support

The NVR is shipped with the following camera handlers:

 American Dynamics 8 Channel IP Encoder Handler

 American Dynamics Fixed IP Camera Handler

 American Dynamics Illustra 400 Camera Handler

 American Dynamics IP Speed Dome Handler

 Arecont Vision Camera Handler

 Axis Camera Handler

 Panasonic Camera Handler

 Sony Camera Handler

Please refer to the Appendices section of this document for the specific details for each camera

handler.

Note: Additional camera handles are available from the camera handler packs available on the

American Dynamics website.

MegaPixel Camera Support

When configuring megapixel cameras (e.g. especially Arecont 5.1 and 8 MP Cameras):

 H.264 codec

 Maximum resolution

Video frame rate less than 5

The live view via the NVR web client (QuickTime) will result in either green screen instead of true

video or distorted video. Live view through the victor Client will occasionally freeze the display.

Viewing through a WAN connection works ok.

The NVR Server V4.1 only supports full field of view (FOV) resolutions and a resolution ≤ 2040 in

width and/or height. Thus, cameras such as the Arecont Vision AV3015M or AV3155M, which

have two 2 FOV resolutions, will only have available one resolution (e.g. 1024x768).
