Installing camera

Select the position for the camera and secure the camera stand. Screw the camera onto the stand. Adjust 
camera to the proper view angle. Make sure the lens is upright relative to the subject. Tighten the thumb 
bolt. First Alert cameras can be either ceiling or wall mounted by simply changing the camera stand 
mounting. See “Camera Orientation” Info box. Holes are provided on both the bottom and back of the 
camera housing to accommodate most mounting requirements. Run cable from camera to DVR location. 
See Information box below on “Longer Cable Runs”.

Camera Orientation

It’s important the camera is mount-
ed correctly to ensure the image is 
not upside down as the camera lens 
can only be positioned one way.

Longer Cable Runs

Longer cable runs may require an upgrade to RG59 
Coax cable. First Alert kits ship with economical AV 
cable that is designed to work well up to the length of 
cable provided, usually around 60 feet. If longer dis-

tances between camera and DVR are required, you will need to upgrade 
to RG59 Coax cable. We provide several lengths up to 300 feet. In ad-
dition, if you need to run cable for in-wall installations, then you may 
require fire rated cable, FT-4/CMR UL approved for in-wall installations.
