4. INSTALLATION
Notes
• A safety wire for the mounting bracket is not supplied with the unit. Prepare the safety wire separately as
needed, and connect it to the safety wire fixing hole and its other end to a heavy-duty place.
• Wrap self-adhesive insulation tape around coaxial cable joints and power cable joints.
4.1. Installation
1. Make a 200 mm diameter hole in the ceiling panel, then route the coaxial cable through it.
Note
Before starting this work, check to be sure that the ceiling thickness is 25 mm or less, and that a space of at
least 250 mm in diameter and at least 100 mm high is allowed behind the ceiling.
2. Slightly loosen 4 bracket mounting screws securing the camera mounting bracket, and rotate the camera
mounting bracket counterclockwise to detach it from the flush ceiling mounting bracket.
