Life Detector Device

Life detector devices locate living persons in disaster rubble, collapsed structures, avalanche debris, and concealed spaces by detecting the physiological signals — heartbeat, respiration, and micro-movement — that distinguish a living body from static debris. These systems give search and rescue teams, military operators, and first responders the ability to confirm human presence and prioritize extraction without excavating blindly through dangerous unstable material.

Radar-based life detectors use ultra-wideband (UWB) impulse radar to penetrate concrete, brick, wood, and soil — detecting the micro-Doppler signatures of chest wall movement from breathing at rates of 12 to 20 cycles per minute and heartbeat at 60 to 100 beats per minute. These signals appear at movement amplitudes of 0.3 to 10mm — far below the threshold of visible motion but fully detectable by UWB radar at frequencies of 1 to 10 GHz. Furthermore, the Delsar Life Detector uses seismic and acoustic sensors rather than radar — detecting low-frequency vibrations transmitted through solid structures from a trapped person’s movement, tapping, or voice. Geophone sensor probes place directly onto rubble surfaces or insert into bore holes to maximize signal coupling with the surrounding structure.

The Findsheng FS-3000 Rescue Radar detects breathing and heartbeat through walls up to 20 meters thick and open air distances to 30 meters — with a 2.5 second response time and visual breathing wave display on the integrated screen. Operating temperature covers -20°C to +55°C for deployment in both cold-weather collapse scenarios in Pakistan’s northern regions and hot summer rubble environments in Karachi and Lahore. Battery-powered designs support fully wireless deployment with runtimes of 4 to 8 hours per charge. Additionally, multi-sensor systems combine UWB radar with acoustic detection and CO₂ concentration monitoring — increasing detection probability on casualties who have lost consciousness and produce no voluntary movement signals.

These devices serve Pakistan Army urban search and rescue units, Rescue 1122 disaster response teams, National Disaster Management Authority (NDMA) response units, Civil Defence teams operating in earthquake-affected areas in Azad Kashmir and KPK, and Pakistan Navy damage control teams requiring confirmed life detection in collapsed or flooded structural environments.

Tactical Supply Pakistan supplies life detector devices for urban search and rescue, earthquake response, and military casualty location procurement across Pakistan.
