The proven human presence detection system now in a compact, portable, handheld form factor. MicroSearch® H3P1 is a human presence detection system that detects hidden people in vehicles. It works by detecting the micro-vibrations in the body caused by the heartbeat.

The H3P1 represents the next level of mobility within MicroSearch’s proven human presence detection technology. While all MicroSearch variants support both mobile and stationary operation, this handheld configuration has been specifically designed for rapid and flexible deployment in the field. Law enforcement and border control agencies can deploy the system without preparation – to check vehicles at traffic stops, weigh stations, parking lots or any other location where time pressure and terrain require flexibility.
