The flagship SJ-3DB 3D radar life detector can be regarded as a technological template. It integrates UWB ultra bandwidth radar and millimeter wave radar technology, captures micro motion signals such as human breathing and heartbeat through Doppler effect, and uses AI intelligent algorithms to achieve real-time positioning in 3D space. Its wall penetrating detection capability has exceeded 50cm, with a detection distance of up to 30 meters. Even if the trapped person is stationary, it can accurately identify them through the accumulation and analysis of echo signals. What is even more commendable is that the device can start up and enter working mode in 3 seconds, and can automatically identify metal walls, helping rescue personnel quickly find weak points in demolition.

SJ-LD4K multi probe life detector provides a comprehensive solution for complex search and rescue scenarios. It is equipped with a 180 degree rotating audio and video probe and a snake eye waterproof probe, a 5.15-meter carbon fiber telescopic rod that can penetrate narrow gaps, a 10 inch high-definition screen that supports 4x detail magnification, and an infrared visible distance of 6-10 meters in dark environments to expose hidden dangers. More considerate is the two-way voice intercom function, which can transmit rescue instructions and distress information in real time, and with 32GB of memory, it can retain on-site audio and video evidence.

All devices have passed rigorous testing, and SJ-3DB complies with the GB 4943.1-2022 standard. From fire rescue to mining accident search and rescue, the life detector of water environment sensing technology builds a technological defense line for life safety with its characteristics of "precision, speed, and durability".
