IRSignalTester

IR Signal Tester is a simple utility for testing infrared (IR) signals using your phone’s camera. Check if a remote control is working, compare signal strength between remotes, or detect infrared light from IR LEDs — all in real time. No ads, no fear-based claims, just a practical tool that works. What the app does Most infrared remotes and IR LEDs emit light that phone cameras can detect — even though your eyes can’t. IR Signal Tester makes this visible and measurable. Use it to: Test TV, AC, and media remotes Check if a remote is weak or failing Compare signal strength between remotes Detect infrared light sources and IR LEDs Features Live IR Detection Real-time camera view Clear “IR detected” indicator Signal strength meter (weak → strong) Remote Control Test Guided 3-second test Signal health results: Good, Weak, Intermittent, or No Signal Helpful explanations for each result Compare Remotes (Pro) Test two remotes side by side Compare signal strength and stability Quickly see which remote performs better Clean & Private Works completely offline No accounts, no tracking Camera access only, used solely for IR detection Who it’s for Anyone troubleshooting a TV or AC remote Technicians and installers DIYers and electronics hobbyists Anyone who wants a simple way to check infrared signals Important note IR Signal Tester detects infrared light signals, not hidden cameras or surveillance devices. Results depend on camera hardware and lighting conditions.
