What are the brands of domestic life detectors?

The life detector finds the position of the "living" by sensing the electric field (generated by the heart) generated by ultra-low frequency radio waves emitted by the human body. Equipped with a special radio wave filter, it can filter out the frequencies of other animals, such as dogs, cats, cows, horses and pigs, which are different from human beings, so that the life detector can only sense the electric field generated by the frequencies emitted by human beings. The instrument is equipped with two different detection poles. The detection distance of the long-distance detection rod can reach 500 meters, and the short-distance detection rod can reach 20 meters. The ultra-low frequency electric field emitted by human body can pass through reinforced concrete walls and steel plates. When the instrument encounters the above obstacles, the detection distance will be reduced, but as long as the operator approaches the detection site forward, the human target to be searched can still be accurately found.

The basic characteristics of life detector include: real-time moving detection, which can penetrate concrete, bricks, snow, ice and mud; Detecting movement and detecting the distance of people in distress; Able to work in all kinds of weather conditions; Intuitive and easy to learn, without a lot of special training; Low requirements for power supply energy; Almost no system maintenance is needed; Firmware programs can be upgraded through wireless or wired networks; There is no need to drill holes, lay cables and mute the environment, so the search and rescue work is simple and easy.

Product category: infrared life detector, audio life detector, radar life detector, dkl life detector.

(dkl lifeguard life detector is the most advanced search and rescue instrument in the world at present, and its volume is only about 1kg). Other life detectors weigh more than 1kg.
