ahh the joys of random self repairing/breaking systemsAnd just like that, randomly, both my cameras are operating at the same time. I guess an IP address expired or something. It doesn't fill me with confidence that they will work reliably.
As for the models, its worked on all of them even back to my test 7608 uk model that last got a firmware in 2017 that has to have new cameras set to 1080p &h264 before they even display and cant display more than 2 on screen at a time before getiing 'noResOurCE!!' crappy thing
