Tap "Start Translating" and confirm the system screen-broadcast prompt. 2. A small lens floats over whatever app you're using. 3. Text next to the lens is recognized, translated and redrawn inside the lens — live, as you scroll.

About

Hidden Camera Detector

Read full description

Is someone watching? CamHunter helps you find hidden cameras, spy devices and Bluetooth trackers in any room: a hotel, an Airbnb, a rental flat, a changing room or your own home. THREE WAYS TO SWEEP A ROOM • Wi-Fi scanner: lists every device answering on the network you're connected to and puts anything unexplained, like an unknown camera, at the top. • Bluetooth sweep: picks up nearby wireless cameras, bugs and trackers that aren't on your network, including devices that broadcast no name. Signal strength rises as you walk closer, so you can home in on the source. • Infrared viewer: night-vision cameras light the room with infrared your eye can't see. Turn off the lights and your phone camera shows the glow. KNOW WHERE TO LOOK Room-by-room guides show where cameras are usually hidden (smoke detectors, USB chargers, clocks, mirrors, plants) and how to build a lens finder from a torch and a paper tube. We also tell you honestly which viral "tests" don't work. MORE TOOLS • World map of reported cameras: check a place before you book • Trusted devices: mark your own gadgets so only the unknowns stand out • Scan history: compare with last time and spot anything new • Last-seen location for Bluetooth devices No technical knowledge needed. Tap Scan, read the plain-language results and follow the guide if something looks off. Your scan results stay on your phone. HONEST LIMITS No phone app can find every camera. A camera that records to a memory card with no wireless connection won't appear in any scan. That's why CamHunter combines network, Bluetooth and infrared checks with a visual search guide. CamHunter Pro unlocks unlimited sweeps, the infrared viewer, the camera map and every guide. Start with a free trial and cancel anytime.
