Problem Solution
No picture / signal • Ensure you have used the correct BNC
connector for your DVR. Use the camera’s black
BNC connector when connecting to Lorex HD
DVRs, and the yellow connector for standard
analog DVRs.
• 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).
• Move your camera to a different location.
Picture is too dark • Check the brightness and contrast settings of
the DVR or monitor.
Night vision is not working • The night vision activates when light levels
drop. The area may have too much light.
Picture is not clear • Check the camera lens for dirt, dust,
spiderwebs. Clean the lens with a soft, clean
cloth.
• Make sure that the cable run is within the
limitations specified in the section ‘Cable
Extension Options’.
Bright spot in video when
viewing camera at night
• Night vision reflects when pointing a camera
at a window. Move the camera to a different
location.
No audio • Audio is only supported on Lorex HD DVRs.
Ensure your camera is connected using the
black BNC connector (see ‘Connecting the
Camera’).
• Ensure DVR volume is turned on / turned up.
• Ensure audio function on camera is turned on
(see ‘Disabling Camera Audio’).
• Ensure audio is turned up on viewing device.
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. This will keep the camera
base flush to the surface when mounted.
Use pliers to break off the perforated metal
tab on the camera cover, and then align the cable notch in the
camera cover with the cable notch in the camera base.
Connect the female power
head to the included power
adapter.
