My system starts up the cameras about a few times a day, for no reason. How do I stop it?

This has been going on for years. At least once a day the system repeats what state it's in. If it's "off", then it turn on the cameras and records for a bit.

I don't like this. Just now I was sitting in my living room with the alarm off, and the cameras just randomly turned on. You can clearly hear the click. And no, I don't mean the light/dark click, that's also a bit annoying.

So at 20:40 tonight the timeline says "System Disarmed", with recordings everywhere. Stop recording me when the system is off!
