Argus – Hidden Camera Detector

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.
