Camera Hacking?

My wife and I were just watching tv and the blue light on the camera in my house turned on. We are the only two that have access to the cameras and neither of us were viewing the camera. I have motion disabled as I only use them when I’m gone. These are brand new cameras from amazon and I have two factor verification set up. I don’t see any events during the time the light came on on the cameras event history. Why would the blue light be on when I’m not viewing the camera?
