I recently purchased the three XT camera systems. I set it up and updated the cameras. If you listen to the recording on all three cameras you pick up the usual static of course but there starts to be a squealing sound like squeaky metal and just progressively gets louder and louder. Has anybody else experienced this? I move the cameras around and that didn’t help. It is a very loud to where you have to turn down your volume on your phone because it hurts your ears. Please help.
