Detectors find and locate unauthorised transmitters, so compare band coverage, sensitivity and scan speed. Wideband models suit routine sweeps, directional probes help pin down a source point by point, and portable units fit travel and temporary inspections. Establish a noise baseline in a known clean room, then compare signal strength changes and narrow the search area with a near-field probe. For frequency-hopping and burst transmissions, choose a faster scanning model so short events are not missed. Typical applications include eavesdropping checks in meeting rooms and offices, inspections of controlled spaces and fault finding on installed equipment. Field teams should confirm battery runtime and alarm thresholds before deployment.
Frequently asked questions
Can it locate hidden cameras or bugs?
It detects active wireless transmissions and, used with a near-field probe, helps narrow the search area. Wired or offline devices still require physical inspection alongside the sweep.
Is sensitivity sufficient?
Sensitivity and scan speed vary by model. Establish a noise baseline in a known clean room, then compare abnormal signal changes; this gives a more reliable judgement than a single reading.
Where is it typically used?
Routine sweeps of meeting rooms, offices and controlled spaces, plus equipment fault finding and event security. Portable models are suitable for travel and temporary inspections.
