Sentry

A room-scanning aid for your phone. Hidden cameras get concealed in everyday objects ā 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 ā infrared light, magnetic fields, bright reflections, and the devices on the network around you ā 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 ā your camera sensor can show infrared light, the kind night-vision cameras emit in the dark (as do remotes and many sensors) ⢠Magnetic Field ā reads spikes near powered electronics, including devices with no Wi-Fi ⢠Lens Reflection Scan ā on-device image analysis flags bright, lens-like glare for you to look at ⢠Wi-Fi Network Audit ā lists devices on the network you're joined to and flags names matching known camera brands ⢠Bluetooth Scan ā 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 ā 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. BUILT PRIVATE Sentry works entirely on your device. No account. No uploads. No tracking. Your scans and any photos you save never leave your phone. WHO IT'S FOR ⢠Travelers in hotels, motels and Airbnbs ⢠Renters checking a new place ⢠Changing rooms, fitting rooms and restrooms ⢠Meeting rooms and private offices SENTRY PRO Sentry Pro unlocks all 5 scan methods, unlimited full-room guided sweeps, and a private scan history.
