I’m fairly certain that I have seen this in our hood. Basically someone or something will cause the motion detection to trigger, and then the video cuts out. Sometimes it goes black, sometimes it’s noise. In the most recent case it was someone whom I don’t recognize walking his dog and holding what I thought was a phone in his hand, and 3 different cameras did the same thing in order, going to white noise.

We didn’t get the cameras for security, we got them to watch the feral cats in the area to help catch them for TNR, but security is a nice extra, so we are considering replacing the Rings with something wired.
