Smoke detectors are common camera-concealment concerns because they have power and a high viewpoint. Most are legitimate safety equipment, so inspect without touching or disabling them.

Important: No consumer app or inspection method can guarantee that a space is camera-free. Use multiple checks and contact a qualified professional for high-risk situations.

Compare every detector in the room

Look for matching models, placement, vents, labels, indicator lights, and mounting plates.

Check the viewing angle

An unusual opening aimed directly at a bed or shower deserves closer visual inspection.

Use light from several angles

A lens may return a sharp reflection, but LEDs, screws, and glossy sensors also reflect.

Do not disable safety equipment

Photograph concerns and contact management or authorities. Removing a real smoke detector creates a serious hazard.
