# Adjusting Average Bitrate

Some camera models do not yield the best setting when Nx Witness tries to configure a target bitrate, resulting in poor image quality. If this is the case you can adjust the bitrate calculation for the device manually.

IMPORTANT! This setting will significantly increase bitrate. Use only if the picture quality is noticeably poor.

To adjust bitrate

1.Open the Camera Settings -> Expert tab.

2.Check Calculate bitrate per GOP instead of bitrate per second.

3.Click Apply, OK or Cancel.

Note: T his setting is ignored when "Keep camera streams and profiles settings" is checked. See Preventing Nx Witness from Changing Camera Streaming Settings".
