HARD CEILING INSTALLATION
1 PREPARE CEILING
Locate the center point of the mounting location. Drill a hole in the ceiling using a
3/32-inch drill. Insert the compass tool into the hole. Use a pencil and the compass
tool to draw a circle on the ceiling. Carefully cut out the circle.
2 INSTALL THE BACK BOX
Attach the conduit fitting, lock nut, and safety chain bracket. Install a safety chain/cable
(not supplied) that will support up to 16 pounds (7.3 kg). Install one end of the safety
chain/cable to the safety chain bracket and the other end to a support structure in the
ceiling.
Prepare the wiring for camera and lens power; refer to Tables A and B for wiring
distances. Pull wiring into the back box through the conduit fitting.
Compress the spring clips on the back box and push it through the hole until the clips
spring back. Tighten the screws until you hear a clicking noise.
