A professional hidden camera detection tool built for privacy-conscious travelers and individuals. Whether you're staying at a hotel, vacation rental, or using a public changing room, this app helps you quickly scan your surroundings for concealed surveillance devices. Four core detection technologies work together to provide comprehensive coverage: 【MAGNETIC FIELD DETECTION】 Uses your phone's magnetometer to detect abnormal magnetic signals emitted by hidden electronic devices. An intuitive gauge displays real-time field intensity with haptic alerts when anomalies are found. 【INFRARED DETECTION】 Captures infrared light invisible to the naked eye through your phone's camera. Automatically identifies and marks IR light sources commonly used by hidden cameras for night vision. Adjustable sensitivity for different lighting conditions. 【WIFI NETWORK SCANNING】 Scans all devices on your WiFi network and probes common camera ports. Calculates a suspicion score based on open ports, device names, and service types. Color-coded risk levels for instant assessment. 【BLUETOOTH SCANNING】 Detects nearby Bluetooth devices and evaluates suspicion levels based on device characteristics. Displays real-time signal strength to help estimate device distance and direction. 【DETECTION GUIDE】 Built-in guide with professional tips for physical inspection, teaching you how to systematically check common hiding spots — even without tools.

Whether you're in a motel room, hotel, Airbnb, locker room, public restroom, fitting room, car, or your own luggage, Sonar helps you inspect the space in minutes. IMPORTANT: no phone app can guarantee with certainty that a space is free of hidden cameras. Sonar is a support tool, each finding comes with a confidence level so you can physically check the spot it flags. Always use it alongside a manual inspection. DETECTOR FEATURES Infrared scanner Point your phone's camera and look for the telltale reflection of hidden spy camera lenses, a common sign in cameras disguised as a button camera, pen camera, charger, smoke detector, or clock. Works best in a dark room and doesn't replace a physical check. Wi-Fi network and Bluetooth device detection Sonar scans the local Wi-Fi network and nearby Bluetooth devices to flag devices with characteristics of connected cameras or trackers. Each result shows a confidence level, not a definitive confirmation. Bluetooth tracker detector Flags signals from Bluetooth trackers nearby: in your car, bag, luggage, or personal belongings, as support against unwanted tracking during travel and everyday life. Guided sweep A practical checklist walks you through spots where cameras and microphones are commonly hidden: outlets, smoke detectors, picture frames, mirrors, chargers, clocks, and more, so you can physically inspect each one.
