Xiaomi Night Vision Not Working? Here’s How to Fix It

If your Xiaomi camera’s night vision is failing while daytime video works normally, you’re not alone. This issue often stems from IR LED malfunctions, firmware incompatibility, or incorrect settings. The good news is that most problems can be resolved quickly with the right steps. Below, we’ll guide you through a series of targeted troubleshooting actions, including Xiaomi-specific tools and model-specific instructions, to get your camera working again.

Quick Fixes to Try First

Before diving into complex diagnostics, try these quick checks that address the most common causes of night vision failure:

  • Power cycle your camera: Unplug the power adapter or remove the battery (if applicable) for 10 seconds, then reconnect. This can resolve temporary glitches.
  • Restart the Mi Home app: Force-close the app and reopen it to refresh the connection with your camera.
  • Check LED status: During low light, point the camera at a white surface. If no IR glow is visible, the IR LEDs may be faulty.
  • Verify power cable/battery: For Smart Camera C200 models, ensure the battery is fully charged (check the app for battery percentage). For CW700S PTZ models, confirm the transformer at the junction box supplies 16-24V AC.
  • Check app login: Log out of the Mi Home app and log back in to ensure your account is properly authenticated.

Step-by-Step Troubleshooting

Check Your Xiaomi Camera’s Night Vision Mode

Xiaomi cameras use 940nm invisible IR LEDs, so you won’t see a visible red glow. To confirm the IR LEDs are active, point the camera at a white surface during low light. If no glow appears, the IR LEDs may be damaged. Navigate to the Mi Home app, go to Device HealthNight Vision Status, and check for alerts. If no alerts appear, ensure the camera is set to Night Vision Mode (found in Camera SettingsNight Vision). For Outdoor Camera AW300 models, enable the IR Cut Filter in the app (navigate to Camera SettingsIR Cut Filter) to prevent IR light from being blocked by the filter during the day.

Update Firmware via Xiaomi’s Firmware Update Checker

Outdated firmware can cause night vision failures. In the Mi Home app, go to Device SettingsFirmware UpdateCheck for Updates. If an update is available, follow the on-screen instructions to install it. For CW700S PTZ models, ensure the firmware is compatible with your camera’s hardware. If the update fails, try reconnecting the camera to a 2.4GHz Wi-Fi network (navigate to Wi-Fi SettingsWi-Fi Band and select 2.4GHz).

Reset Xiaomi Camera Using Model-Specific Procedures

If night vision continues to fail after updating firmware, perform a factory reset using your camera’s model-specific reset procedure:

  • CW700S PTZ: Press and hold the reset button for 7 seconds while the camera is powered on. A voice prompt will confirm the reset.
  • Outdoor Camera AW300: Remove the bottom protective cover with a screwdriver to access the reset button. Press and hold for 10 seconds.
  • Smart Camera C200: Insert a card pin into the reset hole and press and hold for 5 seconds. The LED will flash orange to confirm the reset.

After resetting, re-pair the camera to your Wi-Fi network and reconfigure settings in the Mi Home app.

Diagnose IR Reflection Issues

Night vision failure can occur if the camera’s IR LEDs are reflecting off nearby surfaces like mirrors or glass. To test this, place a white sheet near the camera during low light. If the IR glow is visible on the sheet but not on the wall, the camera is functioning correctly. Adjust the camera’s angle to avoid reflective surfaces. For Smart Camera C300 models, enable the IR Reflection Filter in the app (navigate to Camera SettingsIR Reflection Filter) to reduce unwanted reflections.

Use Xiaomi’s Device Health Check Tool

The Mi Home app includes a Device Health tool that can identify hardware or software issues. To use it, open the app, select your camera, and navigate to Device HealthRun Diagnostic Test. This tool checks the camera’s IR LEDs, Wi-Fi signal strength, and firmware status. If the diagnostic tool reports an issue with the IR LEDs, contact Xiaomi support for further assistance.

When Basic Fixes Don’t Work

If your Xiaomi camera’s night vision still fails after trying the steps above, consider the following advanced troubleshooting options:

  • Factory reset and re-pair: Perform a factory reset using your camera’s model-specific procedure (as outlined earlier), then re-pair the camera to your Wi-Fi network. Ensure the camera is set to 2.4GHz mode during re-pairing.
  • Check for hardware faults: If the Device Health tool confirms a hardware issue (e.g. faulty IR LEDs), contact Xiaomi support for a replacement or repair. For Smart Camera C302 models, ensure the camera is not placed in direct sunlight, as this can damage the IR sensor.
  • Contact Xiaomi support: If the issue persists, visit Xiaomi’s official support page at https://www.mi.com/uk/service/support and provide your camera model, firmware version, and diagnostic results from the Device Health tool.

Root Causes of Xiaomi Night Vision Failure

Night vision failure in Xiaomi cameras is often caused by a combination of hardware and environmental factors. The most common causes include:

  • Faulty IR LEDs: Over time, the IR LEDs may degrade or fail, especially in Outdoor Camera AW300 models exposed to harsh weather.
  • Firmware incompatibility: Outdated firmware can prevent the camera from switching to night vision mode correctly. Ensure your camera’s firmware is up to date using the Firmware Update Checker tool in the Mi Home app.
  • Incorrect settings: If the camera is set to Daylight Mode or the IR Cut Filter is disabled, night vision may not activate. Check these settings in the Camera Settings menu.
  • Environmental factors: Reflective surfaces like mirrors or glass can prevent the IR LEDs from functioning properly. Adjust the camera’s position to avoid these surfaces.

In the UK, construction materials like solid brick and foil-backed insulation can significantly reduce Wi-Fi signal strength, which may indirectly affect night vision performance if the camera relies on Wi-Fi for connectivity. Ensure your camera is placed within 15-20 meters of your router for optimal performance.

Prevention and Long-Term Care

To prevent night vision issues in the future, follow these best practices:

  • Regularly update firmware: Use the Firmware Update Checker tool in the Mi Home app to ensure your camera’s software is up to date.
  • Check storage usage: Monitor the microSD card’s storage capacity in the app. A full card can cause unexpected behavior, including night vision failures.
  • Avoid reflective surfaces: Position your camera away from mirrors, glass, or other reflective surfaces to prevent IR light from being blocked.
  • Inspect hardware periodically: For CW700S PTZ models, check the transformer at the junction box to ensure it supplies 16-24V AC.

Full disclosure: we built scOS to address exactly this—the frustration of cameras that depend on Wi-Fi to function. scOS uses permanently powered cameras connected via ethernet.

Replacement Decisions

If your Xiaomi camera’s night vision continues to fail despite all troubleshooting steps, it may be time to consider replacement. Xiaomi cameras typically have a 3-5 year lifespan for battery-powered models and 5-8 years for wired models. Signs that replacement is needed include:

  • Persistent hardware failures: If the Device Health tool confirms faulty IR LEDs or a broken sensor.
  • Outdated firmware: If the camera no longer receives firmware updates, it may not support newer features or fixes.
  • MicroSD card degradation: If the card is full or damaged, replace it with a high-endurance model like Samsung PRO Endurance or SanDisk High Endurance.

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

Final Tips

  • For Smart Camera C300 models, ensure the camera is set to 2K resolution for optimal night vision performance.
  • If your camera is placed in a UK Victorian terraced house, consider moving it closer to your router to avoid signal loss from solid brick walls.
  • Always use a Class 10 microSD card with at least 32GB capacity for Xiaomi cameras to avoid storage-related issues.
