Pink or Purple Tint on Your HeimVision Camera? Here’s How to Fix It
If your HeimVision camera displays a pink or purple tint in live or recorded footage, it’s often linked to sensor calibration, IR filter issues, or connectivity problems. This guide provides step-by-step solutions tailored to HeimVision models, including HM202A, HM241 NVR systems, and HMD2 Battery Cameras. By following these brand-specific instructions, you can resolve the issue efficiently.
HeimVision Quick Diagnostics
Before diving into complex diagnostics, try these quick checks that address the most common causes of tint issues:
- Restart your camera: For HM202A models, unplug the power cable from the wall for 30 seconds, then reconnect. For HMD2 Battery Cameras, ensure the battery is fully charged and restart the app. For HM241 NVR systems, restart the NVR and all connected cameras via the System → Power Management menu.
- Check app login: Ensure you’re logged into the HeimLink app with the correct account. Log out and back in to refresh the connection.
- Verify LED status: A solid green LED indicates normal operation. If the LED is blinking red or amber, the camera may be experiencing a hardware or connectivity issue.
- Inspect power cable: For wired models, ensure the power cable is securely connected to the camera and the transformer. For battery-powered models, replace the battery if it’s old or swollen.
- Clear app cache: On your smartphone, clear the cache for the HeimLink app. This can resolve temporary glitches that may cause colour distortion.
In-Depth HeimVision Diagnostics
Check Your Camera’s WiFi Signal Strength
HeimVision cameras, particularly the HM202A, rely on a stable 2.4GHz WiFi connection. Weak signal strength can cause sensor calibration issues, leading to a pink or purple tint. Use the Network Diagnostics tool in the HeimLink app under Device Health → Network Diagnostics to check the signal strength. If the RSSI is below -70dBm, consider moving the router closer, reducing obstructions, or installing a WiFi extender.
Verify IR Filter Functionality
The IR cut filter on HeimVision cameras switches between day and night modes. If the filter is stuck in night mode, the camera may display a purple tint during daylight. To check the filter status, open the HeimLink app and navigate to Device Health → Sensor Diagnostics. If the filter is faulty, perform a manual reset by pressing and holding the reset button on the HM202A for 10 seconds. For HMD2 Battery Cameras, hold the reset button on the back for 5 seconds.
Update Firmware for HM202A and HM241 NVR Systems
Outdated firmware can cause sensor calibration issues. For HM202A models, open the HeimLink app, go to Device Health → Firmware Update, and follow the prompts to install the latest firmware. For HM241 NVR systems, access the NVR’s System → Firmware menu and update the firmware for all connected cameras. After updating, restart the camera and check if the tint resolves.
Adjust Motion Detection Settings
HeimVision cameras support motion detection with adjustable sensitivity. If the sensitivity is too high, the camera may capture false motion events, which can lead to sensor calibration issues. To adjust settings, open the HeimLink app, go to Device Health → Motion Detection, and reduce the sensitivity to Medium or Low. This can help prevent false alerts and stabilise the sensor.
Reset HM241 NVR System
If the tint persists after updating firmware and checking signal strength, perform a factory reset on the HM241 NVR system. Right-click the live view screen in the HeimLink app, navigate to System → Default → Factory Default, and confirm the reset. After resetting, reconnect the camera to your network and check if the tint resolves. If not, proceed to advanced diagnostics.

Check for Hardware Faults
If the tint issue persists after basic troubleshooting, it may indicate a hardware fault. For HM202A models, use the Sensor Diagnostics tool in the HeimLink app to check for hardware errors. If the camera reports a hardware fault, contact HeimVision support at https://www.heimvision.com/pages/support. For HMD2 Battery Cameras, replace the battery if it’s old or damaged, as degraded batteries can affect sensor performance.
Contact HeimVision Support
If all troubleshooting steps fail to resolve the tint issue, reach out to HeimVision support directly. Provide them with the following details:
- Model number (e.g. HM202A, HM241 NVR, HMD2 Battery Camera)
- Firmware version (check Device Health → Firmware)
- Steps taken so far
- Screenshots of the tint issue
HeimVision support can guide you through advanced diagnostics or arrange a replacement if the issue is hardware-related.
Heimvision Pink Purple Tint: What's Really Going On
A pink or purple tint on HeimVision footage is typically caused by one of the following:
- Stuck IR cut filter: This prevents proper light filtering, causing colour distortion.
- Weak WiFi signal: The HM202A relies on a stable 2.4GHz connection. Weak signals can destabilise the sensor.
- Outdated firmware: Firmware updates often include sensor calibration fixes.
- Hardware faults: Degraded sensors or damaged components can cause persistent tint issues.
In the UK, construction materials like solid brick walls or double-glazed windows can severely impact WiFi signal strength, exacerbating tint issues. Ensure your router is positioned to maximise signal coverage for HeimVision cameras.
Protecting Your HeimVision Investment
To prevent future tint issues, follow these best practices:
- Regular firmware updates: Keep your HeimVision cameras updated via the HeimLink app to ensure optimal sensor performance.
- Stable WiFi signal: Use a WiFi extender or position the router closer to the camera to maintain a strong 2.4GHz connection.
- Battery maintenance: For HMD2 Battery Cameras, replace the battery every 2-3 years to avoid degradation.
- Annual hardware checks: Use the Sensor Diagnostics tool in the HeimLink app to monitor camera health and detect early signs of hardware faults.
Full disclosure: we built scOS to address exactly this—the frustration of cameras that depend on WiFi to function. scOS uses permanently powered cameras connected via ethernet, eliminating signal interference and sensor calibration issues.
When to Replace Your HeimVision Camera
If troubleshooting steps fail to resolve the tint issue, it may be time to replace the camera. HeimVision cameras typically last 5-8 years for wired models and 3-5 years for battery-powered models. If your camera is beyond its expected lifespan, consider upgrading to a newer model with improved sensors and firmware. Under the Consumer Rights Act 2015, UK consumers have up to 6 years to claim faulty goods.
