1.Using the back box as a template, mark the fastener positions on the mounting surface.
2.Prepare the mounting surface. Pull power and video wire/cable for the dome system. Refer to Table A, Table B, and Table C for wiring distances.
3.Open the hinged door to the back box. Push the tab lock towards the wall of the unit and lift the door open. Pull wiring into the back box.
