DIAGNOSIS The night vision mode is active, overriding the color night vision capability. This happens in low-light conditions before total darkness.
FIX Force color night vision. In the Eufy Security app, go to the camera's settings. Select 'Night Vision'. Change the mode from 'Auto' to 'Color Night Vision'. This ensures the spotlight and color sensor are always used at night.
IF THAT DIDN'T WORK The camera lenses are dirty. Smudges, dust, or spider webs on either the wide-angle or telephoto lens will cause blur. Power off the camera by disconnecting solar. Gently wipe both lenses with a soft, dry microfiber cloth.
HEADS UP Color Night Vision requires the built-in spotlight to activate. This is normal. Ensure 'Spotlight' is set to 'Auto' or 'On' in the lighting settings.
