Sentry: Hidden Camera Scan

A room-scanning aid for your phone. Hidden cameras get concealed in everyday objects — smoke detectors, USB chargers, alarm clocks, vents and mirrors. Sentry uses the sensors already in your phone to measure five different signals in a room and shows you every reading, so you know which spots are worth inspecting by hand. Sentry does not identify cameras. It measures signals — infrared light, magnetic fields, bright reflections, and the devices on the network around you — and each of those signals can come from ordinary electronics just as easily as from a camera. No app, and no dedicated hardware, can find every hidden camera. Sentry is a tool that guides a careful manual check; it is not a guarantee and should never be treated as one. WHAT SENTRY MEASURES • Infrared (IR) Scan — your camera sensor can show infrared light, the kind night-vision cameras emit in the dark (as do remotes and many sensors) • Magnetic Field — reads spikes near powered electronics, including devices with no Wi-Fi • Lens Reflection Scan — on-device image analysis flags bright, lens-like glare for you to look at • Wi-Fi Network Audit — lists devices on the network you're joined to and flags names matching known camera brands • Bluetooth Scan — lists nearby advertising devices with an estimated distance HOW TO USE IT 1. Tap Scan and pan your phone slowly around the room 2. Watch the live readings — a glow, a highlighted box or a signal spike 3. Go to each flagged spot and inspect it with your own eyes and hands The third step is the important one. Sentry tells you where to look; it cannot tell you what is there.
