Camera Will Not Fully Insert into Mount

The lock screw on the camera housing is likely engaged or partially tightened before installation is complete. This screw is meant to secure the camera after mounting but can physically block the camera from sliding fully into place if not properly loosened beforehand.

1. Check the lock screw located on the side of the camera housing. 
2. Loosen the screw completely (do not remove it entirely) to ensure it does not obstruct the mounting path. 
3. Attempt to push the camera into the mount again until it clicks into place. 
4. Once fully inserted, tighten the lock screw to secure the camera. 

Camera Image in the Wrong Direction

Refer to the Installation Guide to ensure you have installed the camera correctly.

No Picture / Signal

• Ensure the camera is connected to a compatible NVR supporting 4K camera input. For full camera compatibility, visit lorex.com/compatibility.
• The camera may take up to 1 minute to power up after being connected to the NVR. Wait two minutes before following the steps below.
• Ensure the camera is connected to your NVR or to your local network.
• If you are not using PoE, you must connect the camera to a 12V DC power adapter (not included).
• If the camera is connected to the LAN, you must search your network for cameras using the NVR. See the NVR's instruction manual.
• Ensure your NVR is properly connected to a TV/monitor.
• There may be an issue with your extension cable run. Connect the camera to the NVR using a different Ethernet cable.

Image Is Too Bright

• Ensure your camera isn't pointed directly at a source of light (e.g., sun or spot light).
• Slide the sunshade forward to block excess light.
• Move your camera to a different location.
• Check the brightness and contrast settings on the NVR.

Image Is Too Dark

• If using during the day, the camera may not be getting enough light. Slide the sunshade backwards to let in more light.
• Check the brightness and contrast settings on the NVR.

Night Vision Is Not Working

• The night vision activates when light levels drop. The area may have too much light.

Image 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.
• Remove the vinyl film from the camera lens when your installation is complete.

Bright Spot In Video When Viewing Camera At Night

• Night vision reflects when pointing a camera through a window. Move the camera to a different location.

No Audio

• Audio is only supported on Lorex HD NVRs. For a list of compatible recorders, visit lorex.com/compatibility.
• Ensure NVR volume is turned on / turned up.
• Ensure audio function on camera is turned on, see Enable Audio Recording.
• Ensure audio is turned up on viewing device.
