{"title":"Listening Device Detectors","description":"\u003ch4\u003eWhat a signal detector finds\u003c\/h4\u003e\n\u003cp\u003eNearly every modern surveillance device transmits: a WiFi camera streaming footage, a 4G bug carrying audio, a GPS tracker reporting location. A signal detector sweeps the radio spectrum and alerts on any of them, which is why one device covers what would otherwise need three.\u003c\/p\u003e\n\u003cp\u003eWhat it cannot find is anything not transmitting: a camera recording to a memory card, or a device switched off. For those, see\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"\/collections\/spy-camera-detectors\"\u003elens detectors\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003eand\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"\/collections\/non-linear-junction-detectors\"\u003enon-linear junction detectors\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch4\u003eConsumer or professional\u003c\/h4\u003e\n\u003cp\u003eEntry-level units tell you a signal is present and roughly where. Professional units identify the frequency and type of transmission, which matters when you need to tell a hidden device from a neighbour's router. If you are sweeping regularly rather than once, the professional units save considerable time.\u003c\/p\u003e\n\u003ch4\u003eHow to sweep a room for a listening device\u003c\/h4\u003e\n\u003cp\u003eStart by turning off everything of your own that transmits: phones on flight mode, laptops off WiFi, smart speakers unplugged. Each of those is a radio source, and a detector has no way to tell yours from anyone else's.\u003c\/p\u003e\n\u003cp\u003eThen work the room slowly with the detector at low sensitivity, raising it until the unit responds to a known source such as a phone briefly taken off flight mode. That sets a useful baseline. Sweep close to surfaces rather than waving the unit around: signal strength falls away quickly with distance, and the difference between a hit and nothing is often a matter of centimetres.\u003c\/p\u003e\n\u003cp\u003eCover the places that have both power and a reason to be there: mains sockets and adaptors, power boards, desk lamps, smoke alarms, air vents, the underside of desks and tables, and anything that has appeared or moved since you were last in the room.\u003c\/p\u003e\n\u003ch4\u003eWhat a bug looks like in practice\u003c\/h4\u003e\n\u003cp\u003eAlmost never a device that looks like surveillance equipment. In practice it is a mains adaptor, a USB charger, a power board, a desk clock, a pen left behind, or a small sealed box taped inside a cavity. The giveaway is rarely the object and usually the circumstance: something in the room that nobody can account for.\u003c\/p\u003e\n\u003ch4\u003eThe limit worth understanding\u003c\/h4\u003e\n\u003cp\u003eA radio detector finds transmission. A device recording to internal memory for collection later transmits nothing at all, and no radio sweep will ever find it. Neither will a sweep find a transmitter that only sends in scheduled bursts, unless you happen to sweep during a burst.\u003c\/p\u003e\n\u003cp\u003eThat is why a proper check is a radio sweep plus a physical search, and why sweeping more than once at different times finds things a single pass misses.
