Is someone watching you?
CamGuard combines 6 detection methods in one guided Room Scan — lens glint, infrared, Wi-Fi network, nearby hotspots, Bluetooth and magnetic field — so a hidden camera has nowhere to hide.
Detection tools
Lens FinderWorks everywhere
Flash + red filter. Spots the glint of a camera lens automatically.
IR / Night VisionWorks everywhere
Front camera sees infrared LEDs of night-vision cameras in the dark.
Wi-Fi Network ScanApp
Finds IP cameras on the same Wi-Fi: RTSP, ONVIF, Hikvision, Dahua, V380…
Nearby HotspotsApp
Spy cams create their own hotspots (V380, IPC, HD-CAM). We flag them.
Bluetooth ScanApp
Lists nearby Bluetooth devices and flags camera / tracker names.
Magnetic SensorApp
Live µT meter with auto-calibration. Beeps near hidden electronics.
Where cameras hide
Hotel, trial room, washroom & rental checklists with the 25 most common hiding spots.
Why CamGuard is different
No ads, no paywall
Other detector apps hide the real scan behind subscriptions and full-screen ads. Every CamGuard feature is free.
Real network detection
We actually probe RTSP, ONVIF and camera web servers on your Wi-Fi — the way security pros check a room.
Automatic glint marking
No guessing: the Lens Finder circles reflections that stay steady across frames, like a real lens does.
Honest results
Every finding shows why it was flagged, so you can check it yourself instead of trusting a fake 'meter'.
