This article provides troubleshooting guidance for addressing issues related to connectivity, functionality, or image quality in both the 4K IP Wired Bullet Security Camera and the 4K IP Wired Dome Security Camera.

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.

Picture 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.

Picture 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.

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.
• 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.

• Ensure NVR volume is turned on / turned up.
