Streaming Configured Port
This is the port number used for the real time streaming protocol (RTSP) connection to this NVR if
more than one NVR is behind the NAT firewall, when video is being streamed to a client
programmatically via RTSP.
Port 554 is the default port for RTSP connection.
However, if two NVRs are behind the same NAT
firewall, they are both exposed as the same public address, so the only way to distinguish between
them is by setting up port forwarding rules at the firewall level. This means that both NVRs listen
on port 554 for HTTPS requests but that publicly NVR1 might be contactable as
https://70.30.22.81:554, while NVR2 is contactable as https://70.30.22.81:100554. The firewall is
configured to accept NVR2 requests at https://70.30.22.81:100554 and forward them to
https://<NVR2 private IP>:554.
This field must be set in scenarios where multip
le NVRs are situated behind the same NAT
firewall. In this example, this field on NVR2 must be set to 10554.
If Failover functionality is active the Failover Streaming Port will be displayed for your information.
It can not be edited.
