Is this your issue?

  • The night-time video feed is completely black, as if the camera is off.
  • The video at night is extremely dark and grainy, making it impossible to see details.
  • The camera does not switch from its colour day mode to the black-and-white night mode.
  • You can see a faint red glow from the IR illuminators, but the video image remains dark.
  • The night vision image is blurry and out of focus, unlike the clear daytime video.
  • Objects very close to the camera appear bright white and washed out, while the background is black.
  • Night vision flickers on and off intermittently throughout the night.

Kuna Night Vision Not Working? Here's How to Fix It

Your Kuna smart light is a crucial part of your home security, and its ability to see in the dark is one of its most important features. When Kuna's night vision stops working, you're left with a security blind spot. Whether your video feed is completely black, blurry, or just not switching to night mode at all, it's a problem that needs to be addressed.

This troubleshooting guide will take you through the most common causes of Kuna night vision failure and provide clear, step-by-step solutions to get your camera seeing in the dark again.

Common Reasons for Kuna Night Vision Failure

Understanding the potential causes can help you quickly identify the right solution.

  • Power Issues: The infrared (IR) LEDs that enable night vision require consistent power. Faulty wiring or an unstable connection can prevent them from turning on.
  • Dirty or Obstructed Lens: A layer of dirt, dust, or even a spider's web over the camera lens can block or reflect the IR light, leading to a blurry or dark image.
  • Software Glitches: Like any smart device, sometimes a simple software bug can prevent a feature from activating correctly.
  • IR Glare: If the camera is mounted too close to a surface (like a wall or soffit), the IR light can bounce back into the lens, washing out the image.
  • Incorrect Settings: It's possible the night vision setting has been accidentally turned off in the app.

How to Fix Your Kuna's Night Vision Problems

Let's start with the simplest fixes first.

1. Clean the Camera Lens and Sensor

This should always be your first step.

  • Take a clean, soft microfibre cloth.
  • Gently wipe the camera lens and the surrounding black area. Make sure to clear away any dust, water spots, or cobwebs.
  • Do not use harsh chemicals or abrasive materials, as these can permanently damage the lens cover.

2. Power Cycle Your Kuna Device

A simple restart can often resolve temporary software glitches. This will reboot the camera and all its components, including the night vision system.

  • Go to your home's circuit breaker panel.
  • Find the breaker that controls the circuit your Kuna light is on.
  • Switch the breaker to the OFF position and wait for at least 30 seconds.
  • Switch the breaker back to the ON position.
  • Give the Kuna a few minutes to reboot and reconnect to your Wi-Fi, then check the feed after dark.

3. Check for Obstructions and IR Glare

Look at your camera's positioning. Is there anything right in front of it?

  • If the camera is too close to a downpipe, wall, or the underside of an eave, the IR light can reflect off it.
  • This reflection overexposes the sensor, making the rest of the image appear dark or completely white.
  • Action: Try to adjust the angle of your camera slightly, pointing it away from the reflective surface. Even a small change can make a big difference.

4. Verify Your In-App Settings

It's worth double-checking that the night vision feature is enabled.

  • Open the Kuna app and go to your camera's Settings.
  • Look for a setting related to "Night Vision" or "IR".
  • Ensure that it is set to Auto. This allows the camera to automatically switch to night vision mode when it gets dark.

5. Check Power and Wiring

If the steps above don't work, the issue could be with the power supply.

  • Safety First: If you are not comfortable working with electrical wiring, please hire a qualified electrician.
  • Ensure the wiring connecting the Kuna fixture is secure and free from corrosion. A loose neutral wire is a common culprit for strange behaviour in smart devices.

If after trying all these steps your night vision is still not working, it may indicate a hardware fault with the IR LEDs. In this case, it's best to reach out to Kuna's customer support for further assistance.

Frequently Asked Questions

Kuna uses infrared (IR) LEDs to illuminate the area in front of the camera. This light is invisible to the human eye but can be seen by the camera's sensor, allowing it to produce a clear black-and-white image in complete darkness. The camera should switch to this mode automatically when light levels are low.

The easiest way is to look at the live video feed at night. If it's in black and white, night vision is active. You can also look directly at the camera in the dark; you should see a faint red glow from the small IR LEDs surrounding the camera lens. If you see no glow and the image is black, there is likely an issue.

Yes, absolutely. The IR LEDs require a stable and sufficient power supply. If the wiring to the light fixture is loose, corroded, or the transformer is failing, it may not provide enough power for the night vision to operate correctly, even if the main light bulb works.

This is a classic sign of IR glare or bounce-back. It happens when the infrared light from the LEDs hits a close-by surface (like a soffit, downpipe, or wall) and reflects directly back into the lens, overexposing the image. Try repositioning the camera angle slightly to avoid the reflection.
