My Foscam camera looks clear by day but white or foggy at night. What should I check?

Applies to: Foscam cameras with infrared or spotlight night modes; available controls vary by model.

Work through these checks

1. Compare a daytime frame with a night frame from the same position. Note whether haze begins exactly when infrared or a spotlight turns on, and whether there is real moisture inside or outside the lens cover.
2. Check for a window in front of an indoor camera, a close wall/eave, protective film, spider webs or dirt. Clean only the accessible exterior using the manufacturer’s permitted method and keep the equipment safely supported.
3. For a camera behind glass, test with infrared illumination disabled through its supported control and suitable external lighting. This is a diagnosis, not a promise that an indoor camera can replace a correctly installed outdoor model.
4. For outdoor models, review the selected night mode and repositioning with the installer if nearby surfaces reflect light. Persistent condensation, a damaged seal or moisture inside the housing needs service assessment.

Confirm the result

Night footage retains useful detail across the intended area without a bright reflected patch. Confirm that detection and recording still cover the required scene.

If you need help

Include these details in your ticket: Model, night-mode settings and redacted day/night pictures showing nearby glass, walls and lights.
