This tool only works if your device is **capable of detecting IR rays** (Back cameras with IR-cut filters may block results). For best detection, use in a **completely dark environment**.
Protocol:
Total Darkness: IR LEDs only glow when room lights are OFF.
Pulsing Dots: Look for steady white/purple glows invisible to naked eyes.
Check Front Cam: If back camera fails, try the front (selfie) camera; it usually lacks IR filters.
