I have an idea but needs some works: Create a network just for the camera(s) - I.e. different wifi router. Find out the server IP that the camera sends it’s video to. Connect a pc/rpi to this camera’s wifi router on WAN port. Assign all camera’s server IP you found above to this pc/rpi. You should get all the traffic from cameras to their server. Up to you now what you are going to do.
