This is real simple now given two things.
- The IP camera you have has a built in web server and you can go a URL and see a stream from the camera.
- That you are using PAC Display Pro.
If yes to both of of those, then simply go to PAC Display configurator and paste in a 'URL Control' (the last icon in the tool box).
Double click and set your camera URL and that's that.
Reason I know this is because I put that request in as a customer a few years back...... Your welcome
