I have several cameras on my property including three outdoor cameras plus a doorbell camera. I am experiencing an issue where after a camera records an event and I go to watch the footage back, the footage is extremely choppy like it skips a frame or two and is not smooth. It’s almost unwatchable. If I actually download the recorded footage, it functions as it should. This seems to occur when I am away from my property and Wi-Fi and using cellular. It occasionally occurs while I’m on Wi-Fi as well. The issue seem to start after I upgraded my iPhone 11 to the new iPhone 13 Pro Max with iOS 15. I have deleted and reinstalled one or so of the cameras, restarted all of the Internet equipment and cameras, and have deleted several of the recording rules and re-install them. I’ve also restarted my Qolsys 2. Nothing seems to improve the problem. My daughters phone is still on iOS 14 and does not seem to experience the problem. I’m not sure if you’ve heard of this yet but I am bringing it to your attention and looking for any other suggestions you may have.
