Pink or Purple Tint on Your Hanwha Vision Camera? Here's How to Fix It

A pink or purple tint in your Hanwha Vision camera footage is typically a sign of a stuck IR cut filter or sensor-related issues. This guide provides step-by-step solutions to resolve the problem, with a focus on UK-specific considerations and model-specific instructions. By following these steps, you can restore clear video and ensure your camera functions as intended.

Quick Fixes to Try First

Before diving into more complex troubleshooting, try these simple steps that often resolve the issue within minutes:

  • Power cycle your camera: Unplug the camera from its power source for 30 seconds, then reconnect it. This can reset the IR cut filter and resolve temporary software glitches.
  • Check LED status: Look for any unusual LED patterns on the camera. A solid red or blinking LED may indicate a hardware fault or low power.
  • Verify power cable/battery: For battery-powered models like the Wisenet QNO-C9083R, ensure the battery is fully charged. For wired models like the Wisenet PNV-A9081R, confirm the transformer is supplying 16-24V AC.
  • Restart the Wisenet mobile app: Close the app completely and reopen it. This can refresh the connection between your device and the camera.
  • Check app login: Ensure you're logged into the correct account and that your app is up to date. Outdated apps can cause display issues.

Check Your Camera's Wi-Fi Band Settings

If your camera is connected to a dual-band router, ensure it's using the 2.4GHz band. The 5GHz band can cause interference with the camera's video processing, leading to colour distortions. To adjust the Wi-Fi band:

For Wisenet QNO-C9083R Models

  1. Open the Wisenet mobile app.
  2. Navigate to Device Settings > Network.
  3. Look for Wi-Fi Band Selection and ensure 2.4GHz is selected.

For Wisenet PNV-A9081R Models

  1. Access the Wisenet mobile app.
  2. Go to Device Settings > Advanced Network Options.
  3. Enable 2.4GHz mode and disable 5GHz if available.

Update Your Camera's Firmware

Outdated firmware can lead to sensor or processing errors, including colour casts. To update your firmware:

For All Hanwha Vision Models

  1. Open the Wisenet mobile app.
  2. Tap on your camera's Device Status.
  3. Look for Firmware Management and check for available updates.
  4. If an update is available, follow the on-screen instructions to install it. Ensure the camera remains powered on during the update.

Important: Always use the Live4NVR video profile when connecting to a Wisenet QRN-1630S NVR. This profile is auto-created during registration and optimises video quality.

Factory Reset and Re-Pairing

If the tint persists after firmware updates, perform a factory reset and re-pair the camera:

For Wisenet QNO-C9083R

  1. Ensure the camera is fully powered on.
  2. Locate the recessed RESET button (blue or white).
  3. Press and hold the button for 5 seconds until the LED flashes rapidly.
  4. After the reset, re-pair the camera through the Wisenet mobile app by navigating to Add Device > Scan for Cameras.

For Wisenet PNV-A9081R

  1. Confirm the camera is powered on and connected to the network.
  2. Press and hold the recessed RESET button for 5 seconds.
  3. Re-pair the camera via the Wisenet mobile app as described above.

Advanced Diagnostics and Support

If the tint remains after all the above steps, consider the following:

  • Check for hardware faults: Inspect the camera lens for cracks, scratches, or obstructions. A damaged lens can cause persistent colour distortions.
  • Use diagnostic logs: In the Wisenet mobile app, go to Device Health > Video Analytics Status. Look for any error codes or warnings related to the sensor or IR filter.
  • Contact Hanwha Vision support: If the issue persists, visit https://www.hanwhavision.com/support/ for further assistance. Provide detailed logs and steps taken so far to expedite support.

Understanding the Root Cause

A pink or purple tint is often linked to the camera's IR cut filter, which switches between day and night modes. If the filter is stuck in the night mode, the camera may display a magenta or purple tint during the day. This can occur due to:

  • Sensor degradation: Over time, the sensor may develop issues that prevent the filter from switching correctly.
  • Environmental factors: In the UK, dense construction materials and low-E windows can interfere with the camera's ability to detect ambient light, leading to incorrect filter activation.
  • Firmware bugs: Outdated firmware may not handle sensor data correctly, resulting in colour distortions.

When to Consider a Managed Alternative

If you find yourself frequently troubleshooting your Hanwha Vision camera for issues like pink or purple tints, a fully managed system like scOS may offer a more reliable solution. scOS eliminates the need for manual resets or firmware updates by handling monitoring and response automatically. With scOS, you avoid the hassle of dealing with IR filter malfunctions, ensuring consistent video quality without the need for complex troubleshooting.

Preventive Maintenance and Long-Term Care

To avoid recurring tint issues, follow these best practices:

  • Regularly inspect the camera: Check for obstructions, lens damage, or signs of wear on the IR cut filter.
  • Keep firmware updated: Enable automatic firmware updates in the Wisenet mobile app to ensure your camera always runs the latest software.
  • Optimize placement: Avoid installing cameras near low-E windows or in areas with high humidity, as these can impact sensor performance.
  • Monitor network settings: Ensure your camera is always connected to the 2.4GHz band for optimal video processing.

Deciding When to Replace Your Camera

If your camera continues to show a pink or purple tint despite all troubleshooting steps, it may be time to consider replacement. Signs that replacement is needed include:

  • Persistent tint issues even after firmware updates and factory resets.
  • Physical damage to the lens or sensor that cannot be repaired.
  • Exceeding the expected lifespan of the camera (3-5 years for battery-powered models, 5-8 years for wired models).

Under the Consumer Rights Act 2015, UK consumers have up to 6 years to claim faulty goods. If your camera is under warranty, contact Hanwha Vision's support team directly for a replacement or repair.

Summary

A pink or purple tint on your Hanwha Vision camera is typically caused by a stuck IR cut filter, sensor issues, or outdated firmware. By following the steps outlined in this guide—power cycling, checking Wi-Fi settings, updating firmware, and performing factory resets—you can often resolve the issue. If the problem persists, consider contacting Hanwha Vision's support or exploring a managed alternative like scOS for long-term reliability.

Frequently Asked Questions

A pink or purple tint typically indicates an issue with the camera's IR cut filter or sensor. First, check if the camera is in day/night mode and whether the filter is stuck. If the camera is outdoors, ensure there's no physical obstruction like a lens cap or debris. For indoor models, verify that the IR cut filter is functioning properly. If the tint persists, proceed with a power cycle and firmware update as outlined in the troubleshooting guide.

To manually reset the IR cut filter on your Hanwha Vision camera, ensure the camera is fully powered on. For models like the Wisenet QNO-C9083R, press and hold the recessed RESET button for 5 seconds. This action may help the camera recalibrate the IR filter. If the tint remains, check for firmware updates in the Wisenet mobile app under Firmware Management.

If your camera is showing a pink or purple tint despite a successful firmware update, the issue may be hardware-related. Inspect the lens for damage or obstructions. For models like the Wisenet PNV-A9081R, ensure the camera is receiving the correct voltage (16-24V AC) from the transformer. If the problem continues, contact Hanwha Vision support directly through their official website for further assistance.

A pink or purple tint can occur if the camera is exposed to extreme temperatures or humidity. Ensure the camera is installed in a location with adequate ventilation and avoid direct sunlight. For UK users, consider the impact of low-E windows and dense construction on sensor performance. If the issue persists, consult a professional installer or refer to Hanwha Vision's support documentation for advanced diagnostics.
