Compression and Image Rate

On the Compression and Image Rate page, you can change the camera’s compression and image quality settings for sending video over the network.

To enable easy access and lower bandwidth usage, the web interface only displays video in JPEG format and cannot be changed. The settings on this page only affect the video transmitted to the network video management software.

The Avigilon cameras covered by the is guide have dual stream capabilities, so even when the camera’s streaming format is set to H.264, the camera's web interface can still display live video in JPEG format.

However, cameras that are connected to an Avigilon encoder do not typically have multi-stream capabilities. So once you set the video streaming format to H.264, live video from that camera is no longer displayed in the web interface.

Note: You can only set the RTSP stream settings in the camera web interface.

Note: The camera may automatically adjust compression quality in order to abide by the bandwidth cap specified.

1. In the Format drop down list, select the preferred streaming format for displaying the camera video in the network video management software.

   If you are using the Onboard Storage feature, select H.264. For more information, see Enabling Onboard Storage.

2. In the Max Image Rate field, enter a number between 1-30 to indicate how many images per second you want the camera to stream over the network.

3. In the Max Quality drop down list, select the desired image quality level.

   Image quality setting of 1 will produce the highest quality video and require the most bandwidth.

4. In the Max Bitrate field, enter the maximum bandwidth the camera can use. You can enter any number between 200-12000 kbps.

5. In the Resolution drop down list, select the preferred image resolution.

6. In the Keyframe Interval field, enter the number of frames between each keyframe. You can enter any number between 2-64.

7. Click Apply to save your changes.
