Some iPhone cameras can display certain infrared sources as pale purple or white light, but filters and camera models vary.
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.
Test your camera first
Point a known infrared remote control at the camera and press a button. If you see a flashing light on screen, that camera can display that source.
Check in a dark room
Infrared night-vision LEDs are easier to notice in darkness, but many cameras use no infrared or activate it only in certain conditions.
Avoid false confidence
A negative result does not clear a room. Continue with visual, Wi-Fi, and Bluetooth checks.
