Why does the night vision video of eufy SoloCam E50 (T8180) appear too bright or dark?
If SoloCam is placed too close to obstacles and in B&W night vision, such as a wall or a lamp, it will reflect the IR light back to the SoloCam lens. Then only objects nearby will appear a bright white, and the rest of the scene will appear dark.
To fix this, try to adjust the angle and direction of the camera; keep objects close to the camera out of the field-of-view of the lens.
