Advanced settings tab (properties)

The advanced settings for the ONVIF Bridge list the default settings for all cameras that the ONVIF Bridge provides to the ONVIF clients when the clients connect and request video streams.

The settings do not reflect the actual configuration of the cameras, and do not affect the video stream. The system uses the settings to speed up the exchange of video between the ONVIF Bridge and the ONVIF client. The ONVIF client will use the actual settings from the RTSP stream.

You can change the default settings that ONVIF Bridge provides to the ONVIF client, for example, if you want the values to reflect the actual configuration of the cameras.

Name	Description
Max days of retention	Default value is 30.
Frame per seconds	Default value is 5.
Width	Default value is 1920. This corresponds to full HD quality.
Height	Default value is 1080. This corresponds to full HD quality.
Bitrate Kbps	Default value is 512.
GOP size	Default value is 5.
Codec	Select one of the H.264 codec profiles. The default value is H.264 Baseline Profile.
Use configurations from cameras	Enable this to use the actual configuration of the cameras instead of the default average values defined above. Note: If you enable this setting, the response time between the XProtect system and the ONVIF clients increases.
Return sequences on command	Enable this to return information for sequences on the DESCRIBE command response.
Maximum number to return	Set the maximum number of sequences to be sent to the client. Default value is 10.
Return from start or end of recording	Select from where to start searching the sequences. from the start or from the end of the recording.
Prefer absolute time over normalized	This setting defines the RTSP server playback response, where the client’s time interval for playback is not specified. Select this option if you want your RTSP server to use real time as opposed to scaled or normalized playback. However, if your client application is set to use either relative time intervals or real time intervals (in UTC), the RTSP server replies with those intervals defined in the client.
