Installation Tips

• Point the camera where there is the least amount of obstructions (i.e.,
tree branches).

• Install the camera where vandals cannot easily reach.

• Secure cabling so that it is not exposed or easily cut.

• This camera is rated for outdoor use. Installation in a sheltered location is
recommended.

Installing the Camera

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.

• If you run the cables along the wall / ceiling,
you must run the cable through the cable
notch on the base. This will keep the camera

base ush to the surface when mounted.
