1. Product introduction:
The multi-mode composite life detector is a life detection product that combines two-dimensional radar, wireless micro-vibration and wireless audio and video detection. It has three detection modes: two-dimensional radar, micro-vibration/audio, and audio and video, and its performance indicators are domestically leading.

This product is based on low-frequency ultra-wideband radar technology, uses heartbeat signals and breathing signals as human life characteristics parameters, directly obtains the two-dimensional coordinates of living bodies, and realizes the detection of weakly moving or stationary living bodies buried in mines or ruins; through micro Vibration principle, supplemented by detecting the audio waves and vibration waves generated by people on the ground or under the ruins, shouting, tapping, scratching, or crawling for positioning confirmation, to determine the approximate location area of ​​the trapped people on the ground or under the ruins , To detect and display the location of life bodies. At the same time, through audio and video technology, the sensor is penetrated into the ruins from the gap to view the video image and talk with the living body in real time, so as to accurately grasp the real situation inside the trapped area; the detection results of the three detection sensors are mutually reviewed and specific fusion strategies are used. Guarantee the detection and rescue effect to the utmost extent.

This product can be widely used in special industries such as mine rescue, armed police, fire fighting, earthquake, etc., for emergency rescue and counter-terrorism rescue missions in mines or under the rubble.
2. Product features:
