Troubleshooting
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 against the base.
B. BENDING THE ARM:
Use a Phillips head screwdriver (not included)
to loosen the adjustment screw closest to the camera base. 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 furthest from the camera base. Rotate the camera
until it is level with the viewing area, then tighten the screw.
ATTENTION:
Test your camera prior to selecting a permanent mounting location by
temporarily connecting the camera and cable to your DVR.
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.

changes between Day/Night viewing modes, an audible clicking noise may
be heard from the camera. This clicking is normal, and indicates that the
