SpyGuard: Hidden Camera Finder

Most “spy camera detector” apps wave the magnetic sensor around and play a scary animation — but a magnetometer alone cannot tell a camera from any other electronics. SpyGuard is built around checks that measure something real. It scans the Wi-Fi you are on for devices streaming video, tells you the brand (Hikvision, Dahua, Tapo, Wyze and more), finds AirTag, Tile and SmartTag trackers and walks you to them with a hot-or-cold meter, and then gives you one dated PDF report for the room.

Staying in a hotel, Airbnb or rental? Six checks take a few minutes: a hotspot checklist of the places cameras are really hidden, a lens finder, an infrared finder, a calibrated magnetic sensor, the Wi-Fi camera scan and the tracker scan. Every result comes from a real measurement, and SpyGuard tells you honestly what a phone cannot see — like a camera on a separate network. No phone app can guarantee a room is free of cameras; SpyGuard is a privacy aid, not professional counter-surveillance equipment. Images and scans are analysed on your phone and never uploaded, with no ads and no tracking. All screens and safety guides can be browsed freely; running scans and creating room reports needs a subscription, every plan includes every tool, and a weekly pass is made for a single trip.
