Argus checks any room for hidden cameras and trackers with four scanners on your iPhone: Wi-Fi, Bluetooth with a tracker locator, a camera finder with Lens and Infrared modes, and a magnet check. The Lens camera finder is free with no scan limit and no account, and so is finding a tracker. Hotel rooms, Airbnbs and holiday rentals, changing rooms, gym lockers, rental cars. No app finds every camera, and no single method does: one in a smoke detector may sit on the room's Wi-Fi, or record to a memory card and touch no network. That is why Argus checks four ways. WI-FI SCANNER Finds the devices on the network you joined and flags those answering on camera ports: RTSP video streams, ONVIF, Hikvision, Dahua, XMEye, V380, Ezviz, Tapo, Reolink. Printers, routers and TVs that name themselves are set aside. Free: the device count, camera alerts and identified devices by name. Argus Pro shows which device it is: address, open ports and what its service says about itself, often the firmware. Blind spot: hotel guest Wi-Fi often keeps devices apart; Argus says so instead of calling the room clean. BLUETOOTH AND FIND IT Lists nearby Bluetooth devices and recognises item trackers: Tile, Samsung SmartTag, Chipolo, Pebblebee, Google Find My Device tags. Find it walks you to one: a ring fills as you get closer, ticks quicken, an optional beep helps. Free: the count, possible trackers and finding them. Argus Pro: every device by name and signal, and Find it for any of them. Blind spot: a paired, silent device doesn't advertise, and iPhone may hide Apple's Find My tags from apps (iOS warns about those itself). CAMERA FINDER: LENS AND INFRARED Lens mode, free: lights off, torch on, sweep slowly. A lens returns a tight bright glint; a red, green or blue filter makes it stand out. Infrared mode, Argus Pro: night-vision cameras light a room with infrared your eyes can't see, and an iPhone camera often can. Argus looks for that light and beeps when it spots one. Blind spot: both need a dark room, and a shiny point or ordinary light can trigger them. A flag means look closer. MAGNET CHECK, ARGUS PRO Hold the phone close to a smoke detector, clock or charger: the dial jumps at the metal and magnets of hidden electronics, with a buzz and a beep. Screws and pipes move it too, so compare with a similar object you trust. A FIVE-MINUTE SWEEP Scan the Wi-Fi. Run Bluetooth from the bed and follow any tracker with Find it. Lights off: sweep everything facing the bed in Lens, then Infrared. Pass the magnet over whatever stood out. Two checks pointing at one object: inspect it. PRIVACY No account, no ads. What a scan finds stays on your iPhone. Camera frames and sensor readings are never recorded; only Wi-Fi and Bluetooth scans are saved, on your phone. Subscriptions run through Apple and RevenueCat; crash reports and usage analytics are not linked to you. No tracking. In 13 languages: English, Spanish, Portuguese, French, Arabic, Turkish, Korean, Japanese, Traditional Chinese, Indonesian, Vietnamese, Hindi, German. FREE AND ARGUS PRO Free: the Lens camera finder; Wi-Fi and Bluetooth scans with their counts, camera and tracker alerts; identified Wi-Fi devices; finding a tracker. Argus Pro: which Wi-Fi device it is and its details; every Bluetooth device by name; Find it for any device; Infrared mode; the magnet check. Requires iOS 16 or later.

Hidden Camera Detector
Read full descriptionHide full description
Check a hotel room, rental or fitting room for hidden cameras in a few minutes. Six scanners built into your phone look for camera lenses, night vision light, wireless cameras and bugs, then give you one clear risk level. Tiny cameras hide in smoke detectors, USB chargers, alarm clocks and picture frames. You can't bring a professional sweeper on every trip, but your phone already has a magnetometer, a camera with a flash, Bluetooth, Wi-Fi and a microphone. This app turns them into a step by step room check. 6 SCANNERS IN ONE APP • Magnetic field: move the phone along objects and hear the signal rise near electronics • Lens finder: the flash and a high contrast filter make camera glass glint • IR illumination: spot the infrared light that night vision cameras give off in the dark • Bluetooth: see nearby devices and follow the signal to the closest one • Wi-Fi network: find IP cameras on your network, with RTSP and ONVIF checks and the maker's name • Acoustic: listen for the 14 to 19 kHz noise some electronics and bugs make FULL ROOM SWEEP • Runs the scanners one after another and adds the results up into a risk level • Room guide shows where cameras usually hide in a bedroom, bathroom or changing room • Every check is saved to history and can be exported as a PDF report MADE FOR TRAVEL • A reminder to check the room when you arrive at a hotel • Home screen widget to start a scan in one tap • Checklist for the first minutes in a new room • Interface in English, Spanish, Portuguese, German, French, Italian, Dutch, Polish, Ukrainian and Russian WHO IT HELPS • Travelers in hotels, hostels and short term rentals • Business trips and conferences • Anyone using a gym, pool or store fitting room • Families checking a new rental before the kids settle in • Renters who want to know what is connected to the Wi-Fi FREE AND PRO Free: magnetic field and acoustic scanners, the room checklist and scan history. Pro: lens finder, IR illumination, Bluetooth and Wi-Fi scanners, the full room sweep, room guide, PDF reports and audio feedback. Every scan runs on your phone. The camera image, scan results and your location stay on the device. A phone is not professional counter surveillance equipment. The app helps you find suspicious spots, but it can't promise to find every device. If you find a camera, don't touch it: take a photo and contact the property and the police.
