EufyCam night vision failures typically stem from IR reflection glare bouncing off nearby walls or insufficient battery power to trigger spotlight mode. The camera's photodiode gets overwhelmed by reflected infrared light, causing exposure compensation that blacks out the rest of the image.

Quick answer

• Reposition camera away from walls, gutters, and posts — leave 6+ inches clearance to prevent IR reflection • Switch to B&W Night Vision mode in Eufy Security app if battery is below 20% • Cycle night vision off/on to reset stuck exposure logic • Never use IR mode behind glass — IR light reflects off windows and blinds the sensor

Symptoms

• Ghost haze — foggy white glow on one side of night video • Pitch black video — audio works but screen is completely dark • Flickering IR — infrared LEDs click on and off repeatedly • Pink daytime video — indicates stuck IR cut filter mechanism

Quick checks

• Check frame edges — look for any wall, soffit, or white surface visible in corners • Verify battery level — spotlight mode requires >20% charge to function • Test different angles — slightly adjust camera position away from reflective surfaces • Listen for mechanical click — IR cut filter should audibly engage when switching modes

Step-by-step fix

1. Open Eufy Security app and select your problem camera
2. Navigate to camera settings → Video Settings → Night Vision
3. Note current mode — check if set to Spotlight, B&W, or Off
4. Switch to "Turn Off" and wait 10 seconds for the change to take effect
5. Toggle to "B&W Night Vision" to use standard IR LEDs instead of power-hungry spotlight
6. Test live view and listen for the mechanical "click" of the IR cut filter engaging
7. Adjust camera angle if walls or eaves are visible in frame corners — infrared bounces off white surfaces 100x brighter than grass
8. Verify 6-inch clearance from any reflective surface on all sides of the camera

If it still isn't working

• Hard reset the IR filter — firmly tap the camera side to unstick a jammed mechanical filter • Add external IR illuminator — place a standalone IR floodlight away from camera for extended range without battery drain • Switch mounting location — move camera to position with clear view and no nearby reflective surfaces • Contact Eufy support if IR cut filter remains stuck after physical intervention

FAQ

Can I use night vision through a window? No. IR light reflects off glass and completely blinds the camera sensor. Set night vision to "Off" for window mounting, but expect poor low-light performance.

Why does spotlight mode work sometimes but not others? Spotlight mode requires significant battery power. When charge drops below 20%, the camera automatically disables white LED spotlight to preserve power.

What's the difference between B&W and Color night vision? B&W uses infrared LEDs for longer range and better battery life. Color mode uses bright white spotlights for shorter range but full-color video.

My video is pink during the day — what's wrong? The IR cut filter is mechanically stuck. Try firmly tapping the camera side. If unsuccessful, the unit needs replacement.
