Point your phone. Tap Scan. Know you're not being watched.
Please read this once. Sentry helps you spot common hidden cameras and nearby devices — it can't guarantee a space is free of all surveillance. Some checks aren't available on every phone or browser. Some devices — like bugs that record silently or send over radio waves — can't be found by any phone app. If anything ever feels wrong, trust your judgment first and leave if you need to.
Ready when you are
Takes about 30–45 seconds. Keep the room dim and quiet if you can — it helps Sentry spot camera lenses and hidden devices.
Cameras and bugs that send video over WiFi usually show up in your router's list of connected devices. This works best on your own home or office WiFi.
