Not sure if your TV remote's battery is dead or if the remote is broken? Stop guessing and find out in seconds! The IR Remote Control & Camera Tester is the fastest and easiest way to test any infrared remote control using your smartphone. Since the human eye can't see infrared (IR) light, this app uses your phone's camera to act as an infrared camera and IR detector, displaying a visible light when it detects a signal from an infrared sensor.
Testing your remote's batteries has never been simpler. Just point your universal TV remote, air conditioner remote, set-top box remote, or any wireless remote at the app's detector and press a button. If you see a bright flashing light on the screen, it means the infrared emitter is working perfectly. If there's no light, the remote is probably broken.
Besides testing whether your remote control works, because the system functions as an infrared camera, you can use this app to detect hidden cameras in hotels, bathrooms, or testing rooms. Any hidden spy camera that uses infrared lights for night vision will glow in the IR tester. Turn your phone into a diagnostic tool, check if your infrared emitter is working properly, and discover hidden components quickly and for free!
