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.
.
NOTE: Input power for the dome is 24 VAC or 24 VDC. Using 24 VAC input power, power consumption is 23 VA per
dome. Using 24 VDC input power, power consumption is 0.7 A (15 watts). Use a 24 VAC transformer with a minimum
of 40 VA per dome.
.
NOTE: As a minimum, UTP requires Cat5, 100-ohm twisted pair cable.

Table B. 24 VAC/24VDC Wiring Distances
The following are the recommended maximum distances for 24 VAC
and 24 VDC applications and are calculated with a 10 percent voltage
drop. (Ten percent is generally the maximum allowable voltage drop
for AC- or DC-powered devices.)
