So, a little over week ago the new cameras that I have purchased started to make a buzzing/static sound which appears to come from there microphone. I've only own this cameras for just two weeks. I own another 5 TP cameras, and these are only ones that seem to be experiencing this issue. How is it possible that both new cameras are having the same issue? Is it a firmware issue? Surely both cameras cannot be going bad at the same time. I have tried everything from resetting the camera, changing resolution, uninstalling and installing, power cycling, etc to no avail. The cameras are both on WiFi with a very good signal.

I was trying to upload the videos but for some reason it wont let me. Any guidance or help would be greatly appreciated. If this continues I have no other choice but to return both cameras.
