This guide is for owners of the eufy Video Doorbell S4 whose night picture is dark, blurred or washed out. eufy says the S4 has colour night vision with dual spotlights. The steps come from eufy’s doorbell night vision guide and eufy’s night vision image quality guide, which cover eufy’s doorbells and cameras in general, and from eufy’s S4 user guide.

What This Problem Means

Something is spoiling the doorbell’s view at night: night vision is turned off, the lens is dirty, or light is reflecting into it.

Common Symptoms

• The night picture is dark
• Night video is blurred or hazy
• The picture is washed out near a wall or light

Safe Checks You Can Try

1. Check night vision is turned on

eufy’s doorbell night vision guide, written for its older doorbells, says to check that Auto Night Vision is turned on in the doorbell’s settings in the app. The S4 has colour night vision with dual spotlights, so look for its night vision setting in the same place.

2. Clean the lens

eufy says to clean the lens regularly, as dust, water drops and cobwebs spoil the night picture. eufy’s S4 user guide says to use only the supplied lens cloth on the S4’s lens and sensors, because other materials may damage them.

3. Avoid reflections

eufy says that installing a camera too close to a wall or light source causes light reflection at night.

4. Know the range

eufy’s night vision guide says its cameras’ night vision normally reaches 3 to 5 m, depending on where they’re installed. eufy doesn’t give a separate night vision range for the S4.
