As though no crook, already wearing the ski mask, would think to cover the camera lens!Not that easy actually. It screws into the wall pretty well and has a "proprietary" screws connecting it to the mount. You need a LOT of force to break it off. You CAN purchase the screwdrivers from Amazon or a replacement from the company, but then you are planning ahead to intentionally steal a doorbell, which is already connected to someone's account. And when you walk up and take the time to unscrew the doorbell, the owner now has a long closeup shot of your pretty mug in 1080p. ;-)
