How to add a PC screen to a Dahua NVR as an ONVIF camera

Dahua NVRs and XVRs support ONVIF cameras from other brands. Screen2ipcam turns a Windows screen into exactly that: a standard ONVIF Profile S camera with an H.264 RTSP stream.

1. Set up the PC

1. Download Screen2ipcam from screen2ipcam.com on the PC whose screen you want to record, and run the installer.
2. Give the PC a fixed IP address (or a DHCP reservation on the router), so the recorder never loses it.
3. Open the control panel. In the Video tab pick the screen, resolution, frame rate and bitrate. For text screens like a cash register, around 10 FPS is plenty.
4. Allow Screen2ipcam in Windows Firewall when Windows asks (private networks).

2. Add it with Device Search

1. Open Camera → Registration on the recorder.
2. Click Device Search. The PC appears as an ONVIF device.
3. Select it, click Add, then edit the channel and enter the Screen2ipcam user and password.

3. Or add it manually

1. In Camera → Registration, click Manual Add.
2. Choose the ONVIF manufacturer / protocol.
3. Enter the PC IP, ONVIF port 8000, the user and the password.
4. Apply, then confirm the live view.

4. Check and record

Open the live view: you should see the PC screen. Then set the channel to continuous or motion recording in the recording schedule.
