A9 7-channel audio probe Audio Life Detector

Short Description:

A9 7-channel audio probe Audio Life Detector

I. Product Overview

The A9 audio life detector is equipped with highly sensitive and anti-interference vibration sensors, sound detectors, and filters. By adjusting the frequency, it can effectively reduce the impact of interference from other machines on the rescue site. It can search for and quickly locate the audio and vibration waves produced by the groans, cries, crawling, tapping, and scratching of trapped people under the rubble.

Equipped with a portable host, supporting wireless remote control, two-way wireless transmission, one click recording and broadcasting, supporting two-way intercom, facilitating communication with the trapped. It has a one click search function to locate wireless microseismic sensors, and distinguishes signal sources through the voice broadcast function of wireless microseismic sensors.
