Pink or Purple Tint on YI Camera Video: What to Do Next

If your YI camera is displaying a pink or purple tint on video footage, this is often linked to sensor or IR filter issues. The tint may appear consistently in both daylight and night mode, or only under specific lighting conditions. While it can be frustrating, targeted troubleshooting steps specific to YI models can resolve the issue. This guide covers everything from quick fixes to advanced diagnostics, ensuring you address the root cause effectively.

Quick Fixes to Try First

Before diving into complex troubleshooting, try these 30-second checks that address common causes:

  • Power cycle the camera: Unplug the power source for 30 seconds, then reconnect. For battery-powered models, remove the battery and reinsert it.
  • Restart the YI Home App: Close the app completely and reopen it to refresh the connection.
  • Check LED status: A blinking or unresponsive LED may indicate a power or connection issue.
  • Verify power cable/battery: Ensure the power cable is securely connected and the battery (if applicable) is fully charged.
  • Check app login: Log out of the YI Home App and log back in to resolve potential authentication issues.

Step-by-Step Troubleshooting

Check Your YI Camera's Wi-Fi Band Settings

YI cameras typically operate on 2.4GHz Wi-Fi (802.11b/g/n). If your router supports dual-band (2.4GHz and 5GHz), ensure your camera is connected to the 2.4GHz network. 5GHz bands may not be compatible with older YI models and can cause connectivity or performance issues. To verify the Wi-Fi band:

  1. Open the YI Home App
  2. Tap Device Health → Network Diagnostics
  3. Check the Wi-Fi band displayed. If it shows 5GHz, navigate to your router's settings and manually assign the camera to the 2.4GHz network.

Update Your YI Camera's Firmware

Outdated firmware can sometimes cause sensor or IR filter malfunctions. To update your camera:

  1. Open the YI Home App
  2. Navigate to Device Health → Firmware Update
  3. If an update is available, follow the on-screen instructions to apply it.

Is your camera battery-powered or wired?

  • Battery-powered → Ensure the battery is above 20% before updating, as firmware updates require stable power.
  • Wired → Check the transformer voltage at the junction box. It must supply 16-24V AC. Incorrect voltage can interfere with firmware updates.

Diagnose the IR Cut Filter

A stuck or damaged IR cut filter is a common cause of pink or purple tints. To check the filter:

  1. Position the camera in a well-lit area with no direct sunlight or reflective surfaces.
  2. Observe the video feed in both daylight and night mode.
  3. If the tint persists in daylight but disappears in night mode, the IR cut filter may be stuck in night mode. If the tint appears in both modes, it could indicate sensor damage.

For YI Dome Camera U Pro users, you can manually test the IR cut filter by using the Device Health → Sensor Test feature in the app. This diagnostic tool may provide additional insights into filter functionality.

Factory Reset Specific to Your YI Model

If firmware updates and basic troubleshooting fail, perform a factory reset using your model's specific method:

  • YI Home Camera 1080p: Press and hold the reset button for 3-5 seconds until the yellow light appears or a voice prompt is heard.
  • YI Dome Camera U Pro: Insert a paperclip or reset pin into the Reset Port at the bottom of the camera and hold until the camera resets.
  • YI Dome Guard Camera: Use a pin to press the reset button until the yellow light turns on and you hear 'Reset is successful'.

After resetting, ensure the camera reconnects to your Wi-Fi network. If the tint persists, proceed to advanced diagnostics or contact YI support.

Advanced Diagnostics and Logs

If the tint issue remains after a factory reset, use the Device Health → Diagnostic Logs feature in the YI Home App. These logs can provide technical details about the camera's performance and may help identify hardware or software issues. Save the logs and share them with YI support for further assistance.

Understanding the Root Causes

A pink or purple tint on YI cameras is often linked to one of three main causes:

  1. Stuck or faulty IR cut filter: This filter switches between visible light and infrared modes. If it's stuck in one position, it can cause persistent colour distortion.
  2. Sensor damage: Physical damage or exposure to extreme temperatures can affect the sensor's ability to render accurate colours.
  3. Outdated firmware: Older firmware versions may have bugs or compatibility issues that lead to colour rendering problems.

UK-specific challenges like dense construction materials (common in older terraced houses) can also interfere with the camera's sensor performance. Ensure the camera is positioned away from direct sunlight, reflective surfaces, or sources of electromagnetic interference.

Prevention and Long-Term Care

To avoid recurring issues, follow these best practices:

  • Regular firmware updates: Check for updates in the YI Home App under Device Health → Firmware Update.
  • Optimal placement: Position the camera away from direct sunlight, reflective surfaces, and sources of electromagnetic interference.
  • Battery maintenance: For battery-powered models, charge the battery fully before long periods of inactivity. Replace the battery if it holds less charge after 300-500 cycles.

Full disclosure: we built scOS to address exactly this — the frustration of cameras that show incorrect colours due to sensor or IR filter issues. scOS uses permanently powered cameras connected via ethernet, eliminating the risk of sensor degradation from intermittent power sources.

When to Consider Replacement

If troubleshooting steps fail to resolve the tint issue, it may be time to consider replacement. YI cameras typically last 5-8 years for wired models and 3-5 years for battery-powered models. Signs that replacement is needed include:

  • Persistent tint after factory reset and firmware update
  • Physical damage to the camera housing or lens
  • Sensor degradation that cannot be resolved through software fixes

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 still under warranty, contact YI support for a replacement or repair.

Frequently Asked Questions

A pink or purple tint typically indicates an issue with the camera's IR cut filter or sensor. This filter switches between visible light and infrared modes. If it's stuck in one position, it can cause colour distortion. Begin by checking the camera's firmware for updates, as outdated software can sometimes cause sensor misbehaviour. If the issue persists, perform a factory reset using the model-specific reset method (e.g. the YI Dome Camera U Pro requires a paperclip in the reset port). If the tint remains, it may indicate a hardware fault, and you should contact YI support for further assistance.

To reset your YI camera, the method depends on the model. For the YI Home Camera 1080p, press and hold the reset button for 3-5 seconds until the yellow light appears. For the YI Dome Camera U Pro, use a paperclip to press the reset port at the bottom. For the YI Dome Guard Camera, use a pin to press the reset button until the yellow light turns on. After resetting, ensure the camera reconnects to your Wi-Fi network and check if the tint persists. If it does, proceed to the next troubleshooting steps.

A pink or purple tint can be caused by a faulty IR cut filter or sensor damage. If the tint appears consistently, even in daylight, it may indicate a hardware issue. Begin by checking for firmware updates in the YI Home App under **Device Health** → **Firmware Update**. If the tint persists after updating, perform a factory reset. If the issue still occurs, it may require professional inspection or replacement. Ensure the camera is positioned away from direct sunlight or reflective surfaces, which can interfere with the sensor.

Battery-powered YI cameras may experience colour distortion if the battery is low. Check the battery level in the YI Home App. If it's below 20%, charge the camera fully before testing. For wired models, ensure the transformer voltage at the junction box is between 16-24V AC. Low voltage can cause the camera to malfunction, leading to incorrect colour rendering. If the voltage is correct, proceed to check the Wi-Fi signal strength and firmware updates.
