Unifi Night Vision Not Working? 5 Fixes That Actually Work

Unifi Night Vision Not Working? 5 Fixes to Try First

If your Unifi camera's night vision is malfunctioning but daytime video works normally, there are several brand-specific steps you can take immediately. This section covers the most common causes and their quick fixes. These actions should take no more than 30 seconds each and address the most likely culprits:

• Power cycle your camera: Unplug the power adapter or disconnect the PoE cable for 10 seconds, then reconnect it. This resets the camera's internal state and can resolve temporary glitches.
• Restart the UniFi Protect app: Close the app completely and reopen it. This clears any corrupted app data that might be interfering with night vision settings.
• Check the camera's LED status: Look for a solid green or blue light on the camera's housing. A blinking or absent light may indicate a power issue or a hardware fault.
• Verify the power cable/battery: Ensure the power cable is securely connected to both the camera and the wall outlet. For battery-powered models, check the battery level in the app — if it's below 20%, charge it fully before proceeding.
• Log in to your UniFi Protect account: If you're not logged in, the app may not have access to your camera's settings. Make sure you're using the correct credentials and that your account is active.

These steps are designed to address the most common causes of night vision failure without requiring complex configuration changes. If none of these work, proceed to the deeper troubleshooting steps below.

Check Your UniFi Camera's Night Vision Mode Settings

The first place to investigate is the Night Vision Mode setting in your camera's configuration. This setting determines whether the camera uses infrared LEDs for low-light visibility or switches to a different mode. To access this setting:

1. Open the UniFi Protect app on your mobile device or desktop.
2. Tap on the Device Health tab for the affected camera.
3. Scroll down to Camera Settings and locate the Night Vision Mode option.
4. Ensure it's set to Auto or On. If it's set to Off, the camera will not use infrared LEDs even in low-light conditions.

For AI 360 models, this setting may be located under Advanced Camera Settings. If you're unsure where to find it, refer to the camera's user manual or consult the UniFi Protect help documentation.

For G5 Bullet and G5 PTZ Models

These models often have a IR Cut Filter that can malfunction over time. To check its status:

1. In the UniFi Protect app, go to Device Health → Camera Settings.
2. Look for the IR Cut Filter option. If it's listed as Malfunctioning, the filter may need to be replaced or the camera may require a firmware update.
3. If the filter is functioning, ensure that the Night Vision Mode is set to Auto or On.

For AI 360 Models

AI 360 cameras use a different mechanism for night vision. To check their settings:

1. In the UniFi Protect app, navigate to Device Health → Camera Settings.
2. Look for the IR Reflection option. This setting adjusts how the camera handles infrared light reflecting off surfaces like white walls or mirrors. If this setting is misconfigured, it can cause flickering or reduced visibility during the night.
3. Adjust the IR Reflection setting to a lower value if you're experiencing flickering or glare.

Update Your UniFi Camera's Firmware

Outdated firmware can sometimes cause night vision issues. To ensure your camera is running the latest firmware:

1. Open the UniFi Protect app and go to Device Health → Firmware Update.
2. Check if there's an available update for your camera model. If so, follow the prompts to download and install the update.
3. After the update is complete, restart the camera to apply the changes.

For G5 Bullet and G5 PTZ models, firmware updates are often required to fix known bugs related to the IR Cut Filter or Night Vision Mode. If the camera is stuck in a Restoring mode after an update, refer to the UniFi Protect support documentation for troubleshooting steps.

For AI 360 Models

AI 360 cameras may require a specific firmware update to resolve night vision issues. To check for updates:

1. In the UniFi Protect app, go to Device Health → Firmware Update.
2. Look for the AI 360 firmware version. If an update is available, install it immediately.
3. After the update, reset the camera to factory defaults and reconfigure it to ensure the new firmware is properly applied.

Use the UniFi Protect Network Diagnostics Tool

If your camera's night vision is failing intermittently or not at all, it could be related to network connectivity. The Network Diagnostics tool in UniFi Protect can help identify issues like IP conflicts or unstable connections:

1. In the UniFi Protect app, go to Network Diagnostics.
2. Run the diagnostics test for the affected camera.
3. Review the results for any errors related to IP Address Conflicts, Network Latency, or Bandwidth Limitations.

For G5 PTZ models, a high Bandwidth Usage can sometimes cause the camera to drop packets during low-light conditions, resulting in flickering or no night vision. To address this:

• Check the Bandwidth Monitor in UniFi Protect → Device Health → Bandwidth Monitor.
• If bandwidth usage is consistently high, consider upgrading your network infrastructure or reducing the camera's resolution in Camera Settings.

Contact UniFi Support for Advanced Diagnostics

If the above steps have not resolved your night vision issues, it may be necessary to contact UniFi Support for further assistance. Before reaching out, ensure you have the following information ready:

• The Camera Model and Firmware Version.
• A screenshot of the Protect Health Dashboard and Network Diagnostics results.
• A detailed description of when the issue occurs (e.g. consistently, intermittently, only in certain lighting conditions).

When contacting support, mention the UniFi Protect app version and any error messages you've encountered. This will help the support team diagnose the issue more quickly.

Root Causes of Unifi Night Vision Failure

Night vision failure in Unifi cameras can be caused by several factors, including:

• IR Cut Filter Malfunction: The IR cut filter is a critical component that allows the camera to switch between normal and infrared modes. If it's faulty, the camera may not use infrared LEDs even in low-light conditions.

• Incorrect Night Vision Mode Settings: If the Night Vision Mode is set to Off, the camera will not activate infrared LEDs, resulting in no visibility during the night.

• Poor Network Connectivity: If the camera is experiencing network instability or high bandwidth usage, it may drop packets during low-light conditions, causing flickering or no night vision.

• Faulty Power Supply: For G5 Bullet and G5 PTZ models, a faulty power supply or incorrect transformer voltage can cause the IR LEDs to dim or fail entirely.

• Environmental Factors: High-reflectivity environments, such as those near white walls or mirrors, can cause infrared light to reflect back into the camera, creating glare or reducing visibility.

Keeping Your Unifi System Running Smoothly for Your Unifi Camera

To prevent night vision issues from recurring, follow these best practices:

• Regularly Update Firmware: Ensure your camera's firmware is always up to date to fix known bugs and improve performance.

• Monitor Network Bandwidth: Use the Bandwidth Monitor in UniFi Protect to track usage and avoid overloading your network.

• Check Power Supply Regularly: For G5 Bullet and G5 PTZ models, ensure the transformer voltage is set to 16-24V AC at the junction box.

• Avoid High-Reflectivity Environments: Place your camera away from white walls, mirrors, or other reflective surfaces to reduce glare and improve visibility during the night.

• Perform Routine Maintenance: Clean the camera's lens and housing regularly to prevent dust or debris from obstructing the IR LEDs.
