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 for hotels, Airbnbs and rentals. Somebody hid a camera in the room you paid for. It happens — and you can check for it in two minutes, with the sensors already in your phone. SpyGuard is a hidden camera detector and spy cam finder that gives you four independent ways to sweep a space: lens detection, infrared, Wi-Fi and magnetic. No app can prove a room is clean, and SpyGuard doesn't claim to. No account. No ads. Nothing leaves your phone. FOUR TOOLS • Camera Finder — the flash blinks while the camera watches. A lens sends light straight back where it came from, so a real lens lights up with every flash and vanishes in between. A screen, a lamp or a window reflection doesn't. That difference is what SpyGuard measures — and it's why this finds lenses that a steady flashlight misses. • Infrared Finder — night-vision cameras light a room with infrared you can't see, but your front camera can. Turn the lights off and sweep the room. • Network Scanner — lists every device on the Wi-Fi you're connected to, asks each one whether it speaks ONVIF (the protocol security cameras use), and flags what identifies itself as a camera. A device answering that query isn't a guess — it's the device's own statement. • Magnetic Sensor — measures your phone's magnetometer against a baseline taken in that room, so it reacts to what's behind the wall instead of to the Earth's own field. WHAT IT CANNOT DO No app can prove a room is clean, and SpyGuard doesn't claim to. It makes your search far better than looking with your eyes alone — and it tells you where each method stops: • Lens detection needs a dark room and a direct line of sight. Glass, screw heads and shiny plastic reflect too, which is why a hit reads "possible", not "found". • Infrared detection finds 850 nm emitters. The 940 nm "no-glow" kind is invisible to most phone cameras. • Network scanning only sees the network you're on. Guest networks often isolate devices from each other, and a hidden camera may run its own Wi-Fi. • Magnetic readings react to ordinary electronics too. Use them together, and finish with your own eyes. YOUR PRIVACY • No account. No email, no name, no password. • Camera frames are analysed on your device and discarded. Nothing is recorded, nothing is uploaded. • Scan reports, IP and MAC addresses and magnetic readings stay on your phone. • SpyGuard never asks for location, contacts, photos or the microphone. A MANUAL GUIDE, TOO Smoke detectors, alarm clocks, wall outlets, mirrors, vents, air purifiers — where cameras actually get hidden, what to look for, and the two-way mirror fingernail test. Plus what to do if you find one: don't unplug it, cover the lens, photograph it in place, contact the platform and the police. FREE AND PAID The Network Scanner, Infrared Finder, Magnetic Sensor and Quick Scan are free, with no daily limit. Camera Finder — the flash-modulated lens detection — is the paid feature, unlocked with a weekly subscription or a one-time lifetime purchase. WHERE TO CHECK Hotel rooms and hostels. Airbnb and short-term rentals. Changing rooms and fitting rooms. Locker rooms and public bathrooms. Meeting rooms and offices. Rental cars. Anywhere you undress, sleep or speak freely — a two-minute sweep costs you nothing. Cameras get hidden in smoke detectors, alarm clocks, USB chargers, power outlets, air purifiers, TV boxes, picture frames, mirrors and air vents. SpyGuard tells you where to look and what a real lens looks like when the flash hits it. Available in 14 languages.
