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 

flush to the wall / ceiling 

when mounted.

Troubleshooting

To install the camera:

1.  Use the camera base to mark holes in the wall 

or ceiling.

2.  If you are running the cables along the wall / 

ceiling, run the cable through the cable notch 

on the base. If you are running the cables 

through the wall, connect the power and video 

cables according to the section ‘Connecting 

the Camera.’

3.  Mount the camera to the wall or ceiling using 

the included mounting screws.

4.  Loosen the camera stand screws using the 

included allen key. Loosen the adjustment 

ring.

5.  Move the camera to the desired position, 

and while holding it firmly in place, turn the 

adjustment ring on the camera stand clockwise 

to tighten. Tighten the screws on the camera 

stand.
