Eufy Night Vision Not Working? Here's How to Fix It
If your Eufy camera is failing to activate night vision despite working fine in daylight, you're not alone. This issue can stem from hardware malfunctions, software misconfigurations, or environmental factors. The good news is, most problems can be resolved with a few targeted steps. This guide walks you through quick fixes, in-depth troubleshooting, and advanced diagnostics to restore your camera's night vision capabilities.
Quick Fixes for Eufy Night Vision Issues
Before diving into complex diagnostics, try these rapid checks that address the most common causes:
Power Cycle the Camera
Unplug the camera's power source (or remove the battery for battery-powered models) for 30 seconds. Reconnect it and wait for the device to boot up fully. This can resolve temporary glitches affecting the IR LED or camera settings.
Restart the Eufy Security App
Close the Eufy Security app completely and reopen it. Sometimes, app caching or temporary bugs can disrupt night vision functionality. If the issue persists after restarting, force-close the app and relaunch it.
Check the IR LED Status
Open the Eufy Security app, navigate to Device Health > Connection Status, and look for the IR LED Test option. This allows you to manually activate the night vision LEDs. If they do not illuminate, the issue may be hardware-related.
Verify Power Supply
For battery-powered models like the eufy Video Doorbell S330, ensure the battery is fully charged. A low battery can prevent the camera from activating night vision. For wired models, confirm the power cable is securely connected to both the camera and the transformer.
Confirm App Login
Log out of your Eufy account in the app and log back in. Sometimes, authentication issues can disrupt camera functionality, including night vision.
Deep Troubleshooting for Eufy Night Vision Problems
If quick fixes fail, move to these more detailed steps:
Check Your Eufy Camera's Wi-Fi Band Settings
Eufy devices like the eufyCam S3 Pro and eufy Video Doorbell S330 rely on the HomeBase S380 to extend your Wi-Fi signal. Ensure the HomeBase is set to 2.4GHz mode for better penetration through walls and obstacles. In the Eufy Security app, go to Device Health > Connection Status and select 2.4GHz mode if it's not already active.
Inspect for Signal Interference
Place your Eufy camera in a location with minimal obstructions between the HomeBase and the camera. Thick walls, metal objects, or other Wi-Fi devices can degrade signal strength, causing night vision to fail. Move the camera closer to the HomeBase or reduce obstructions if possible.
Update Firmware on Your Eufy Camera or HomeBase
Outdated firmware can cause compatibility issues, including night vision failures. In the Eufy Security app, go to Device Health > Firmware status and check for updates. If an update is available, follow the prompts to install it. For the eufy S4 Max NVR, ensure the NVR itself is also updated to the latest firmware version.
Model-Specific Reset Procedures
If firmware updates fail to resolve the issue, perform a factory reset on your camera. For battery-powered models like the eufyCam S3 Pro, press and hold the Sync button for 10-15 seconds until the LED begins to flash. For the eufy Video Doorbell S330, press and hold the Sync button on the back of the doorbell for 10 seconds until the indicator light signals the reset has started. After resetting, re-pair the camera with your Eufy account in the app.
Diagnose IR Reflection Issues
Sometimes, reflective surfaces like windows, mirrors, or metallic objects can cause IR light to bounce back, preventing the camera from detecting motion. Inspect the camera's surroundings for such surfaces. Adjust the camera's angle or position to avoid direct line-of-sight with reflective materials. For eufyCam S3 Pro models, use the Service Log feature in the app to check if the camera is detecting motion correctly in low-light conditions.
Advanced Diagnostics and Support
Factory Reset for Eufy S4 Max NVR
If your eufy S4 Max NVR is not functioning correctly, perform a factory reset. Insert a paperclip into the reset pinhole on the NVR and hold it for 5-30 seconds until the device beeps or the LED flashes. After resetting, reconnect the NVR to your router and re-pair all cameras via the Eufy Security app.
Retrieve Diagnostic Logs
For persistent issues, retrieve diagnostic logs from your Eufy device. In the Eufy Security app, go to Device Health > Service Log and share these logs with Eufy support at service.eufey.com/uk. This can help identify hardware or software issues affecting night vision.
Root Causes of Eufy Night Vision Failures
Night vision failures on Eufy cameras often stem from three main causes:
Hardware Malfunctions
Faulty IR LEDs or damaged sensors can prevent night vision from activating. This is more common in older models or cameras exposed to harsh environments. If the IR LED test in the app fails, the issue may be hardware-related.
Software Misconfigurations
Incorrect settings, outdated firmware, or app bugs can disrupt night vision. Ensure your camera's Night Vision Mode is set to 'Auto' or 'On' in the app's settings. Also, confirm the HomeBase S380 is updated to the latest firmware version.
Environmental Factors
Reflective surfaces, poor Wi-Fi signal strength, or physical obstructions can interfere with night vision. Ensure the camera has a clear line of sight to the HomeBase and is positioned away from reflective materials.
Prevention and Long-Term Care for Eufy Night Vision
To avoid future night vision issues, follow these best practices:
Regular Firmware Updates
Keep your Eufy camera and HomeBase updated to the latest firmware versions. This ensures compatibility and resolves known bugs affecting night vision.
Optimize Wi-Fi Signal Strength
Position your Eufy HomeBase S380 in a central location, away from obstructions. Use 2.4GHz mode for better penetration through walls and ensure the camera is within range of the HomeBase.

Replacement Decisions and Device Lifespan
If your Eufy camera is beyond repair, consider replacement options. Eufy cameras typically last 3-5 years for battery-powered models and 5-8 years for wired models. If your camera is experiencing persistent night vision failures and is past its expected lifespan, it may be time to invest in a newer model. Under the Consumer Rights Act 2015, UK consumers have up to 6 years to claim faulty goods, though this applies only if the device is still under warranty or the issue is due to manufacturing defects.
Final Tips and Next Steps
If all else fails, contact Eufy support directly at service.eufy.com/uk. Provide them with detailed information about the issue, including any diagnostic logs retrieved from the app. For Eufy S4 Max NVR systems, ensure the Ethernet uplink is properly connected to your router and the NVR is receiving a stable internet connection. Avoid using low-endurance microSD cards for continuous recording, as they can degrade faster and affect camera performance.
