BACK BOX AND LENS
1. Prepare the mounting surface:
a.
Cut a 6-inch diameter hole in the ceiling.
b.
Pull all wiring through the hole and terminate all wires (if not already terminated).
2. Install the lens on the back box:
NOTE: Megapixel lenses are designed and tested to deliver optimal image quality to megapixel cameras. 
A standard definition lens installed on a megapixel camera will limit the resolution of the camera and 
create poor image quality.
a.
Remove the cover from the lens mount.
b.
Screw the lens onto the lens mount. Be careful to prevent dust from entering the space 
between the lens and the imager. If necessary, use clean, compressed air to remove any 
foreign matter (refer to the instructions shipped with the lens). Make sure the lens does not 
touch the camera imager when installed.
c.
Connect the auto iris lens to the 4-pin connector located on the side of the camera. Refer to 
Figure 3 for pin designation and iris drive connector information.

3. Connect the network cable to the RJ-45 network port on the side of the back box.
