I've got 2 of these cameras and I lose my ptz control about every 30 minutes. I have to unplug them from the switch and everything works fine again. I've gone through 3 different poe+ switches, I've done a factory reset on the back of the cameras, firmware is up to date. One camera is about 75-100 ft away, one is around 30-40 ft away and they both drop off at the same time. Do you think this is a camera issue or some type of ip conflict? I love the cameras when they work but holy hell I am over it
