eufy Video Doorbell C30 Night Vision Not Working? Here’s How to Fix It
At night your eufy Video Doorbell C30 uses infrared or, on colour-night-vision models, a starlight sensor with a spotlight. A dark or washed-out picture usually comes down to settings, glare or a dirty lens.
What This Problem Means
If your eufy Video Doorbell C30 is showing this fault, working through the checks below in order resolves it in the large majority of cases. Each step is safe to try yourself and follows eufy’s official guidance.
Common Symptoms
- Black screen at night
- No infrared glow
- Washed-out or glaring image
- Reflections spoiling the picture
Safe Checks You Can Try
1. Check the night vision setting
In Camera Settings > Night Vision, set it to Auto (or the colour/spotlight mode on models that support it).
2. Clean the lens
Wipe the lens gently with a soft cloth — dust and smears badly affect infrared.
3. Avoid glare
Move the camera away from bright lights and reflective surfaces, and don’t film through glass, which bounces IR straight back.
4. Allow some ambient light
Colour night vision needs a little ambient light; in total darkness the camera falls back to black-and-white infrared (or its spotlight, where fitted).
5. Update the firmware
In the eufy Security app, check Camera Settings > Device Info for a firmware update, which can fix night-vision bugs.
