SONAR: HIDDEN CAMERA AND TRACKER DETECTOR Sonar helps you check for hidden cameras, hidden microphones, and Bluetooth/Wi-Fi trackers, a privacy inspection support tool with infrared, Wi-Fi network, and Bluetooth scanning. 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. Clear, straightforward results See the confidence level of each finding, with real-time visual indication, no technical jargon.

Hidden Camera Bug Detector

Vigil turns your phone into a five-channel sweep for hidden cameras, microphones and trackers. It is the check worth doing before you unpack in a hotel room, a holiday rental, a changing room or an office. FIVE WAYS TO FIND A CAMERA Infrared: night-vision cameras flood a dark room with light your eyes cannot see. The front camera can see it, and Vigil under-exposes the sensor until only the emitters are left. Lens glint: glass reflects light straight back at its source. Sweep with the torch and a lens answers with a small, hard, motionless spark. Magnetic: every camera worth hiding holds a magnet and a switching supply, both of which bend the local field. This is the only channel that finds a camera that is switched off. Wi-Fi: lists every device on the network you are on and flags the ones answering on the ports IP cameras stream over. Bluetooth: finds battery cameras, voice recorders and trackers that advertise themselves, and tells you when one is getting closer. WHERE TO LOOK Smoke detectors, air vents, alarm clocks, chargers, mirrors, TV bezels, power strips, air fresheners and decorative holes. Each mode explains what it is measuring and how to sweep properly. PRIVATE BY DESIGN Every scan runs on your device. No video is recorded, no network data leaves the phone, no account is needed and nothing is uploaded — a privacy tool that phoned home would be a contradiction. Vigil raises suspicion, it does not prove anything. If you find something you cannot explain, stop, leave it in place and call the front desk or the police.
