LNE9383, LNE9393, Nocturnal Series, N4 - Nocturnal Series N4 4K IP Wired Dome Camera with Motorized Varifocal Lens: Troubleshooting

The following article provides some troubleshooting tips for setting up your 4K Motorized Varifocal IP PoE Wired Dome Camera.

No picture / signal

• Ensure the camera is connected to a compatible NVR supporting 4K camera input. For full camera compatibility, see the Product Compatibility Chart.
• 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 spotlight).
• 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 camera's limitations. Review the camera cable options in the camera's quick start guide for the maximum cable run length.

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.

Picture is in color in dark conditions

• This camera comes with an image sensor that is extra sensitive to light, meaning that the camera stays in color mode at low-light conditions. For instructions on how to make your camera switch to night mode, visit lorex.com, and search for “How do I make my camera switch to night mode?”.

No audio

• Audio is only supported on Lorex NVRs. For a list of compatible recorders, see the Product Compatibility Chart.
• The camera does not have built-in audio/speakers. You must connect external audio devices such as a self-powered microphone and self-powered speaker to the NVR. For full details, see the article N883 Series: Connect Audio Devices.
• Ensure NVR volume is turned on / turned up.
• Ensure audio is turned up on viewing device.

Low frame rate (frames per second)

• To obtain the maximum 30 frames per second, you must connect to a compatible recorder. For a complete list of compatible recorders, see the Product Compatibility Chart.
• If your recorder is capable of supporting 30 frames per second, you will need to disable smart motion detection in order to use the maximum frame rate.
