Infrared Camera Detector - This app has one more tool that detects infrared lights. Simply open the infrared detector and look for white light that appears on the screen but is not visible to the naked eye. This white light indicates infrared light. It could be an infrared camera. Your normal camera can detect it too, but what we have is a built-in function with luminescence effect.
