Hidden Device Detector: Camera

Check a hotel room, rental, changing room or car for hidden cameras and Bluetooth trackers in about 30 seconds. Hidden Device Detector runs five checks with the sensors already in your phone and tells you why it flagged something, so you know exactly where to look.

FULL ROOM SCAN IN ONE TAP
Bluetooth, Wi-Fi and the magnetic field are checked together. You get a clear result: what looks normal, what is worth a look, and the reason behind every flag. Pick the room type (hotel, bedroom, bathroom, changing room, car) and the scan is saved as a report.

WI-FI CAMERA SCANNER (FREE)
Join the room's Wi-Fi and the app lists every device on it. A device is flagged as a possible camera only when it acts like one: it answers camera discovery (ONVIF), offers a video stream (RTSP) or names a camera maker. Your router and your own phone are never flagged. Device details are free, never locked.

BLUETOOTH TRACKER DETECTOR
Finds tracker tags around you, including Apple Find My items such as AirTag, Samsung SmartTag, Tile, Google Find Hub tags, Chipolo and Pebblebee. Open the tracker finder and walk: the rings and a beep get faster as you get closer. Distance is shown honestly as very close, close, nearby or far. Mark your own devices as "mine" so they stop showing up.

CAMERA LENS FINDER WITH FLASH TEST
Dim the lights and sweep slowly. A camera lens reflects your flashlight straight back, and the finder marks those small bright spots. Not sure? Run the flash test: the app blinks the torch and checks which spots blink with it (a lens reflection) and which stay lit (an LED or a lamp). An infrared mode with the front camera helps you see the night-vision lights some cameras use.

MAGNETIC DETECTOR
A live gauge and chart against a baseline you set in the middle of the room. Move the phone slowly along smoke alarms, clocks, chargers, vents and decor. Tips for common false alarms (chargers, speakers, metal) are built in, and you can choose the sensitivity.

2-MINUTE ROOM CHECKLIST
Step-by-step spots to check by eye for each room type: smoke detectors, mirrors, USB chargers, air vents, picture frames and anything facing the bed or shower. Flag a spot and take a photo.

EVIDENCE REPORT
Every scan becomes a report with the findings, the reasons and your photos. Rename it, add captions, export a PDF, or send a ready-made message to the host, the hotel or the police.

TRIP MODE
Joined a new Wi-Fi? Trip Mode reminds you to scan the room. It listens for network changes instead of scanning all the time.

QUIET MODE
No sound, no torch and calmer screens, for checking a changing room without being noticed.

HONEST ABOUT LIMITS
No app can find every hidden camera. A camera that is switched off, records only to a memory card, or uses mobile data or another network may not show up. A tracker that is not broadcasting cannot be detected. A flag means "look closer", not proof. Use all the checks together and inspect suspicious spots yourself.

FOUND SOMETHING?
Do not touch it. Take photos from where you stand, leave the room if you feel unsafe, and tell the host, the hotel or local authorities. The report helps you explain what you found.
