Useless. I should have done more research before buying, and any thief worth their salt knows that modern security cameras don't have a red flashing light, which is counterproductive as it lets the thief know you don't actually have a security camera. I took it off and threw it away because it broke while taking it off. The screws it came with were junk and snapped off so I had to break it to remove and couldn't get it back once removed.
