Loud clicking noise on doorbell 2

I'm getting a loud clicking noise sometimes when I go into live view... Doesn't happen every time, it's very loud when physically near and is picked up over the live stream speakers too. I can't figure out how to stop it or how to force it to occur, but it happens more often now. I can provide a sample too but it sounds a bit different in person than to recording. It's hardwired, signal is good and voltage.
