A. ROTATING THE ARM: Loosen the adjustment ring by turning it
counter-clockwise. Rotate the arm of the camera up to 360°, then
tighten the adjustment ring.
B. BENDING THE ARM: Use a Phillips head screwdriver (not included)
to loosen the adjustment screw. Bend the arm of the camera up to
90°, then tighten the screw.
C. LEVELING THE CAMERA: Use the screwdriver to loosen the
adjustment screw. Rotate the camera until it is level with the viewing

ATTENTION:
Test your camera prior to selecting a permanent mounting location by

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 surface
when mounted.
