Milestone Open Network Bridge settings

The following table describes the settings for the Milestone Open Network Bridge server and ONVIF clients.

When these settings are changed, for them to take effect, Milestone Open Network Bridge server must be restarted.

Name

Description
ONVIF port

The port number of the ONVIF port. ONVIF clients use this port to connect to the Milestone Open Network Bridge server.

The default port number is 580.
RTSP port

The port number of the RTSP port. The Milestone Open Network Bridge server sends RTSP video streams through this port to ONVIF clients.

The default port number is 554.
Enable WS-Discovery

WS-Discovery (Web Services Dynamic Discovery) is a technical specification that defines a multicast discovery protocol to locate services on a local network.

Default camera settings (as reported to the ONVIF clients)

These settings for the Milestone Open Network Bridge list the default settings for all cameras that the Milestone Open Network 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 Milestone Open Network Bridge and the ONVIF client. The ONVIF client will use the actual settings from the RTSP stream.

You can change the default settings that Milestone Open Network 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 5.
Codec

Select one of the codec profiles. The default value is H.264 Baseline Profile.

Use configurations from devices setting

Default is enabled. Enable this to use the actual configuration of the devices instead of the default average values defined above.

If you enable this setting, the response time between the XProtect system and the ONVIF clients may increase.

Ignore privacy masking in the ONVIF clients setting

Default is disabled. Enable this to view video streams that have liftable privacy masks.

To view the video streams in the ONVIF clients, you must have the permission to lift privacy masks.

RTSP tab

Real Time Streaming Protocol settings

Name

Description
Skip gaps in recordings

When the client performs RTSP playback of recorded video, if there are gaps in the recordings, they will be omitted during playback.

This is enabled by default.
Repeat frames

Some players do not behave well when the distance between frames is more than 500 ms. This setting repeats individual frames and adjusts the timestamp, so that when played the video appears to have more frames.
Maximum time between frames: This setting defines the time in milliseconds between frames. The default value is 350 milliseconds.
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.
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. The 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.

RTSP multicast settings

Name

Description
IP address

The multicast address that the hosts can subscribe to. The default value is 239.1.2.3.

TTL

The maximum number of routers a data packet can be forwarded.

Real-time Transport Protocol settings

Name

Description
RTP protocol for AAC streams

The payload format that indicates the encoded format of the data. Most clients support both RFC 6414 and RFC 3640, but if you experience issues with the audio streaming, you can try changing the RTP protocol.
