Arlington Cam-Light™ kit to install any security camera (with base diameter up to 7 in) on a suspended or drywall ceiling panel. For power or low voltage, it installs fast with a 4 in hole saw, saving time and money. It's a tested assembly that holds up to 50 lb on a suspended or drywall ceiling. It fits any security camera hole pattern because you drill the holes in the mounting plate. Larger cameras (base diameter from 4.5 to 7 in) mount directly to the box flange.
