Ethernet Cable

12V DC 

(optional)

Before installing the camera:

• Decide whether to run the 

cables through the wall (drilling 

required) or along the wall.

• If you run the cables along the 

wall, you must run the cable 

through the cable notch on the 

base. This will keep the camera 

base flush to the wall when mounted.

To install the camera:

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.  Loosen the 3 cover screws and then lift the cover 

away from the camera.
