@jurgen_432355664863482Drift Boss To display a feed on a Network Video Recorder (NVR) without using camera ports directly, you can utilize network-based video streaming protocols or methods. Here's a general approach:

1. **IP Camera Setup**: Connect your IP cameras to the same network as your NVR. Ensure that the cameras are configured properly and are accessible via the network.

2. **Network Configuration**: Make sure that the NVR and IP cameras are on the same subnet and that there are no network restrictions preventing communication between them.

3. **RTSP (Real-Time Streaming Protocol)**: Many IP cameras support RTSP for streaming video. Check the documentation of your cameras to find out if they support this protocol.

4. **RTSP URL**: Each camera will have a unique RTSP URL that you can use to access its stream. This URL typically looks like `rtsp://<camera_ip>:<port>/<stream_path>`.

5. **NVR Configuration**: In the NVR settings, there should be an option to add IP cameras using their RTSP URLs. You'll need to enter the RTSP URL for each camera you want to add.

6. **Viewing the Feed**: Once the cameras are added to the NVR, you should be able to view their feeds through the NVR's interface or client software. The NVR will pull the video stream from the cameras over the network.

7. **Network Bandwidth**: Keep in mind the network bandwidth requirements, especially if you have multiple cameras streaming to the NVR simultaneously. Ensure your network infrastructure can handle the traffic.

By following these steps, you can display feeds on an NVR without directly connecting the cameras to the NVR's ports. Instead, the NVR retrieves the video streams from the cameras over the network using RTSP or similar protocols.
