Verify Your UniFi Camera’s Video Quality

Pink or purple tint on your UniFi camera’s video feed is a common issue that often stems from hardware or software misconfiguration. This problem typically occurs when the camera’s IR cut filter fails to switch between day and night modes, or when sensor calibration is off. While the tint can be frustrating, it’s usually fixable with the right steps. This guide will walk you through quick fixes, in-depth troubleshooting, and advanced diagnostics specific to UniFi devices, ensuring you resolve the issue efficiently.

Quick Fixes to Try First

Before diving into complex diagnostics, try these 30-second checks that address the most common causes of colour distortion:

Check the Protect Health Dashboard

Open the UniFi Protect app, navigate to Device Health, and look for any IR cut filter errors. If the app flags an issue, follow the on-screen instructions to reset the filter manually.

Verify PoE Voltage

For G5 models, use a multimeter to check the PoE voltage at the junction box. Ensure it’s within 16-24V AC. If the voltage is outside this range, consult your network provider to adjust the power supply.

Restart the Camera

Press and hold the reset button on the camera’s rear panel for 5-10 seconds. This will restart the device and may resolve temporary software glitches.

Step-by-Step Troubleshooting

If the quick fixes don’t resolve the issue, proceed with these detailed steps to diagnose and fix the problem.

Check Your UniFi Camera’s Day/Night Mode Settings

Incorrect day/night mode settings can cause persistent colour distortion. Follow these steps:

  1. Open the UniFi Protect app.
  2. Select your camera from the Device List.
  3. Tap Device Settings → Advanced → IR Cut Filter.
  4. Toggle the IR Cut Filter manually between Day and Night modes.
  5. Observe the video feed to see if the tint resolves. If the camera fails to switch modes, the IR cut filter may be stuck or damaged.

Update Your UniFi NVR Firmware

Outdated firmware can cause compatibility issues with newer cameras. To update your NVR:

  1. Open the UniFi Protect app.
  2. Tap System → Firmware Update.
  3. If an update is available, follow the prompts to install it. Ensure the NVR is connected to a stable power source during the update.
  4. After the update, restart the NVR and re-pair the camera through the Add Device wizard.

Reset the Camera and Re-pair with the NVR

If the tint persists, a factory reset may be necessary. This process will erase all custom settings, so ensure you back up any important configurations first:

  1. Locate the reset button on the camera’s rear panel.
  2. Hold the button for 10 seconds until the LEDs flash rapidly.
  3. Once reset, open the UniFi Protect app and re-pair the camera via the Add Device wizard.
  4. During re-pairing, ensure the NVR is updated to the latest firmware.

Check the Network Diagnostics

Network instability can sometimes cause colour distortion. To check your camera’s network health:

  1. Open the UniFi Protect app.
  2. Navigate to Device Health → Network Diagnostics.
  3. Review the Signal Strength and Bandwidth Monitor metrics. If the signal is weak (below -70dBm), consider relocating the camera or using a Wi-Fi extender.
  4. For G5 PTZ models, ensure the PoE+ (802.3at) connection is stable and free from interference.

Advanced Diagnostics and Factory Reset

If the issue persists after the above steps, consider these advanced troubleshooting methods:

Force Manual IR Cut Filter Toggle

Some cameras may require a forced toggle of the IR cut filter:

  1. Open the UniFi Protect app.
  2. Tap Device Settings → Advanced → IR Cut Filter.
  3. Toggle the IR Cut Filter manually between Day and Night modes. Repeat this process several times to ensure the filter is not stuck.
  4. If the filter fails to toggle, the camera may require hardware inspection.

Access the Storage RAID Status

For AI 360 models, storage issues can indirectly affect video quality. To check the NVR’s storage health:

  1. Open the UniFi Protect app.
  2. Tap Settings → Storage → RAID Status.
  3. If any drives show errors, replace them immediately. Use surveillance-rated HDDs (WD Purple/Seagate SkyHawk) for optimal performance.

Contact Unifi Support

If the problem remains unresolved, contact Unifi support via their official portal. Provide them with the following details:

  • Camera model and serial number
  • UniFi Protect app logs (accessed via Settings → Logs)
  • A video sample showing the tint issue
  • Firmware version of the camera and NVR

Understanding the Root Causes

The pink or purple tint on your UniFi camera is typically caused by one of the following issues:

  • Stuck IR Cut Filter: The camera’s IR cut filter may be physically stuck in night mode, preventing proper colour balance during the day.
  • Sensor Degradation: Over time, the camera’s image sensor may degrade, leading to colour distortion.
  • Firmware Incompatibility: Outdated firmware on the NVR or camera can cause unexpected behaviour, including colour issues.
  • Network Instability: Weak Wi-Fi signals or unstable PoE connections can cause the camera to malfunction, leading to tinted video.
  • Environmental Factors: Extreme temperatures or exposure to moisture can affect the camera’s performance, particularly in outdoor models.

Preventive Maintenance and Long-Term Care

To prevent future issues, follow these best practices:

  • Regular Firmware Updates: Ensure your camera and NVR are always running the latest firmware. Check for updates in the UniFi Protect app under System → Firmware Update.
  • Monitor Network Health: Use the Bandwidth Monitor and Network Diagnostics tools in the UniFi Protect app to ensure your camera has a stable connection.
  • Protect Against Environmental Damage: For outdoor models, ensure the IP66 rating is intact and the lens is free from debris. Avoid exposing cameras to extreme temperatures or moisture.
  • Replace Components Proactively: If your NVR’s HDDs show signs of wear, replace them immediately to avoid data loss and potential video quality issues.

Full disclosure: we built scOS to address exactly this—the frustration of cameras that show incorrect colours due to stuck IR filters or sensor degradation. scOS uses permanently powered cameras connected via ethernet, eliminating the need for unreliable IR filters.

When to Replace Your Camera

If all troubleshooting steps fail and the tint persists, it may be time to replace your camera. Consider the following:

  • Wired Cameras: Replace if the issue occurs consistently across multiple NVRs or after a factory reset.
  • Battery-Powered Cameras: Replace if the battery is over 3 years old or shows signs of degradation (e.g. reduced charge capacity).
  • NVR HDDs: Replace if the Storage RAID status shows drive errors or if the NVR is over 5 years old.
  • MicroSD Cards: Replace if the camera uses a microSD card and the issue occurs after prolonged use.

Under the Consumer Rights Act 2015, UK consumers have up to 6 years to claim faulty goods (5 years in Scotland). If your camera is under warranty, contact the manufacturer for a replacement or repair.
