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.

To install your camera:

Mounting screws
(4×)

1. Use the included mounting template to mark holes for the
screws. Drill holes for the mounting screws.

NOTE: Insert the included drywall anchors if you are

installing the camera in drywall.

2. Connect cables as shown in the section “Connecting the
Camera”.

3. Feed the cable through the mounting surface or cable notch

and mount the camera stand to the surface using the

provided screws.

4. Use a Philips screwdriver (not included) to loosen the
adjustment screw.

5. Adjust the camera position as
needed.

6. Tighten the adjustment screw
to secure the position.

7. Remove the vinyl lm from
the camera lens when your
installation is complete.
