Camera loses video when switching to night vision.

Video is permanently black & white (even during day time).

Video is unclear, soft, or distorted.


How do I install the LOREX C831CD camera?

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.

To install your camera:

Step 1. Rotate the camera base counterclockwise to separate it from the ball camera, adjustment ring, and dome cover.

Step 2. Use the included mounting template to mark and drill holes for the included mounting screws.

Step 3. Feed the cable through the camera base. If you are running the cables against a wall or ceiling, make sure to pass the cable through the cable notch as shown above.

Step 4. Connect the cables as shown in the section ‘Connecting the Camera’.

Step 5. Mount the camera base to the mounting surface using the included screws and drywall anchors (optional).

Step 6. Place the adjustment ring over the dome cover, then place both over the ball camera. Twist the adjustment ring clockwise halfway onto the camera base. Do not tighten all the way.

Step 7. Move the ball camera to the desired position. While holding the ball camera firmly in place, twist the adjustment ring the rest of the way to secure it to the camera base. Holding the camera prevents it from moving while securing the adjustment ring.

Step 8. Remove the vinyl film from the camera lens when your installation is complete.
