A room-scanning aid for your phone. Hidden cameras get concealed in everyday objects โ€” 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 โ€” infrared light, magnetic fields, bright reflections, and the devices on the network around you โ€” 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 โ€ข Infrared (IR) Scan โ€” your camera sensor can show infrared light, the kind night-vision cameras emit in the dark (as do remotes and many sensors) โ€ข Magnetic Field โ€” reads spikes near powered electronics, including devices with no Wi-Fi โ€ข Lens Reflection Scan โ€” on-device image analysis flags bright, lens-like glare for you to look at โ€ข Wi-Fi Network Audit โ€” lists devices on the network you're joined to and flags names matching known camera brands โ€ข Bluetooth Scan โ€” 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 โ€” 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.

Is someone watching? A hidden camera in a rental or a hotel room is small, cheap, and easy to miss. Glint gives you four ways to look โ€” and tells you plainly what each one can and can't see. FREE, AND COMPLETE The network scan is free forever, and the results are never blurred or held back. Glint lists every device sharing your Wi-Fi and says in plain words what each one probably is: a router, a printer, an Apple TV โ€” or something that matches a known camera manufacturer. Most apps in this category show you a scary number and charge you to see what's behind it. We don't. The live magnetic sweep is free too. WHAT GLINT PRO ADDS โ€ข Infrared detector โ€” spots the IR LEDs a night-vision camera gives off in a dark room โ€ข Lens glint finder โ€” catches the reflection a lens throws back at your torch โ€ข Guided room sweep โ€” ten places, in the order cameras are actually found: smoke detectors, alarm clocks, USB chargers, air vents, the two-way mirror test โ€ข Saved reports โ€” a record of every room you've checked NO LOCATION. NO SERVER. Glint never asks for your location โ€” it doesn't need it. Everything runs on your iPhone: the camera feed is analysed frame by frame in memory and never recorded, the network scan never leaves your local network, and nothing is uploaded anywhere. There is no server to leak. HONEST ABOUT LIMITS No app can prove a room is clean, and any app that says otherwise is selling you something. A network scan can't see a camera recording to an SD card. Infrared works in the dark, not in daylight. Glint tells you this at the end of every sweep, because a false sense of safety is worse than none. Glint Pro is a one-time purchase โ€” pay once and keep every tool, on every device you sign in with. There is no subscription and nothing to cancel. Terms of Use: https://identifier-proxy.vercel.app/glint/terms/ Privacy Policy: https://identifier-proxy.vercel.app/glint/privacy/ Terms also include Apple's standard EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
