The MicroSearch® G4.0 Wired Human Presence Detection System is a 'one-of-a-kind' security inspection solution that detects hidden persons in vehicles or containers by sensing the vibrations caused by the human heartbeat. Unlike the portable H3P1 model, this is a wired system designed for more permanent or semi-permanent applications, such as at uniGATE Screening Checkpoints. It offers reliable detection of stowaways without the need for X-ray radiation.
