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.
