Hero Sweep

Hero Sweep turns your phone into four real scanners and walks you through checking a room, one step at a time. It is free, and it is built to tell you the truth about what it can and cannot see. FOUR CHECKS, IN THE RIGHT ORDER Wi-Fi. Finds devices on the network you are on, then asks them directly whether they stream video. Bluetooth. Listens for nearby devices broadcasting names used by common hidden cameras. Lens. A camera lens throws light straight back at you. A window or a chrome fitting does not. The scanner strobes your torch and watches for a reflection that answers it. Infrared. Night-vision cameras light a dark room with infrared your eyes cannot see. Hero Sweep works out which of your cameras can see it, then looks. Manual check. The places cameras are actually hidden: smoke detectors, chargers, clocks, vents, anything with power facing where you sleep or undress. WHY FOUR, AND NOT ONE Each check reaches something the others cannot, which is the whole point of doing all of them. The lens check does not care whether a camera is online. A lens reflects light whether the camera is powered, unplugged, recording to a memory card, or sitting on its own hidden network. What it needs is a clear line of sight. Infrared finds a camera that is watching in the dark, but only while it is powered and lighting the room. The Wi-Fi check only sees the network you are on, so a camera on a network of its own will not answer there. The lens and infrared checks still might. EVERY SWEEP ENDS WITH A COVERAGE MAP You get a plain list: what was checked, what was not, and what a phone cannot reach at all. Every scanner shows its limits in one line, on screen, while you use it. Findings are only ever Possible or Likely. There is no confirmed-camera verdict, because a phone cannot establish that. YOUR SWEEP STAYS ON YOUR PHONE Sweeps, photos and reports never leave this device. There is no account and nothing to sign into. No ads, no paywall, and every scanner is free. SAVE AND SHARE A REPORT Each sweep can be saved with photos and notes, and shared as a report if you need to hand one to a host, a hotel or the police.
