Problem

Solution

No picture / signal

• The cameras are only compatible with certain Lorex 

HD DVRs. For the full list of compatible recorders, 

visit 

lorex.com/compatibility

.

• Ensure your TV or monitor is on the correct input 

channel. Common terms for input channels: INPUT, 

AV CHANNEL, LINE1, LINE2, AUX.

• Ensure your DVR is properly connected to your TV 

or monitor. 

• Ensure connections are properly connected.

• Ensure the camera power supply is plugged in.

Picture is too bright

• Ensure your camera isn’t pointed directly at a source 

of light (e.g., sun or spot light).

• Check the brightness settings of the DVR and 

monitor.

• Move your camera to a different location.

Picture is too dark

• Check the brightness and contrast settings of the 

DVR and monitor.

Night vision is not working

Troubleshooting

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. Use pliers to break off the 

perforated plastic tab on the camera base. 

This will keep the camera base flush to the 

surface when mounted.

Connect the female power 

head to the included power 

adapter.

NOTES:

1.  The extension cable must be a single stretch of cable between the 

DVR and camera. You cannot connect multiple extension cables to 

each other.

2.  For cable runs above 200ft (61m), you must connect the power 

adapter directly to the camera, rather than at the end of the 

extension cable.

3.  Indicators that your cable run may be too long:

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

•  Video is unclear, soft, or distorted.

4.  For more information on extension cables, visit 

lorex.com

down on the release button. Pull the camera base away 

from the dome cover. 

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

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.

4.  Connect the cables as shown in the section ‘Connecting the 

Camera’.

5.  Mount the camera base to the mounting surface using the 

included screws and optional drywall anchors.

6.  Place the dome cover over the ball camera. Push the dome 

cover against the camera base until it clicks into place.

7.  Move the ball camera to the desired position. 
8.  Remove the vinyl film from the camera lens when your
