The ports
Windows Firewall
When Windows asks, allow Screen2ipcam on private networks. If you missed the prompt, allow TCP 8000 and 554 and UDP 3702 for the local network.
You can change the ONVIF and RTSP ports in the program. If you do, use the new numbers on the NVR and in the firewall.
Test it
Play rtsp://PC-IP:554/screenlive in VLC from another computer on the network. If it plays, the ports are open.
FAQ
Do I need to open ports on the router?
No, not for a local NVR. Only the PC firewall matters on the local network.
Is 3702 required?
Only for automatic discovery. You can always add the camera by IP without it.
