GlintGuard: Device Detector

Detect hidden cameras & spy devices with magnetometer and IR camera scanning

GlintGuard helps you detect hidden cameras, GPS trackers, and other surveillance devices using your phone's built-in sensors and camera.
KEY FEATURES
• Magnetometer detection — Use your device's magnetometer to detect electromagnetic fields from hidden electronics within 15–25 cm range.
• IR camera scanning — Turn off the lights and scan rooms with your camera to spot infrared LEDs used by many hidden cameras. Look for bright white or purple dots that are invisible to the naked eye.
• Multiple detection modes — Choose from Deep Scan, Sensor, Graph, and Meter modes for different ways to search your space.
• Room-specific tips — Get guidance for bedrooms, bathrooms, changing rooms, and outdoor areas.
• Instructions & FAQ — Learn how detection works and get answers to common questions.
HOW IT WORKS
The app measures magnetic field strength in microtesla (µT). Normal background levels are typically 25–65 µT; higher readings may indicate nearby electronic devices. For camera detection, your phone's camera can see near-infrared light that hidden night-vision cameras emit.
IMPORTANT
GlintGuard is for indication purposes only and cannot guarantee detection of all hidden devices. Use it as one tool among others to check your privacy. For best results, use the app in a quiet electromagnetic environment and move your phone slowly when scanning.
