ATTENTION:
Test your camera prior to selecting a permanent mounting location by temporarily connecting
the camera and cable to your NVR.
Before Installing the Camera
• Decide whether to run the cables through the
wall / ceiling (drilling required) or along the wall / ceiling.

the cable through the
cable notch
on the base. This will keep
the camera base flush to the surface when mounted.
Use pliers to break off the perforated metal tab on the
camera cover, and then align the cable notch in the camera
cover with the cable notch in the camera base.
