Wireless Audio (Sound Wave) Life Detector

Audio (sound wave) life detector

Brand: Sheng Bolan

Model: BE-50R/4

An audio life detector is an acoustic detection device designed to detect and locate victims following earthquakes, explosions, and other disasters. Landslide Survivors of mine accidents or building collapses who are buried beneath collapsed structures. Life detectors can detect through specialized sensing probes. Micro-vibration detection These life signals enable precise localization of trapped individuals, and the probe boasts high sensitivity. It is ideal for rescue operations in rubble caused by earthquakes, collapses, and building collapses.

1. Extra-large color LCD display;

2. Supports two-way voice intercom and features recording and broadcasting functions.

3. Equipped with a wireless audio sensor;

4. The vibration signal can be converted into a bar graph for display, allowing clear identification of the signal source.

5. The entire device features a waterproof design and can be used in rainy or humid environments.

Suitable for fire rescue, municipal services, mine rescue, and other emergency response agencies, this equipment is ideal for rescue operations in confined spaces and areas that are difficult to access using conventional methods—such as locating trapped victims in collapsed buildings, deep wells, mines, and other confined spaces; searching for missing persons in wrecked vehicles, aircraft, ships, and trains—especially in areas that are hard to spot with the naked eye—as well as in sewer lines, mine shafts, and underground locations.

1. Host: A 10-inch touchscreen host with bar graph display, capable of converting detected vibration signals into bar graphs for clear identification of signal sources. The host’s screen comes with a built-in electronic manual, and the host supports voice broadcasting, recording, and playback functions.

2. Audio Sensor: The device is equipped with four wireless sensors, with an audio detection range of 20 meters. The audio sensor features high sensitivity and a detection frequency ranging from 0 to 5000 Hz. It can automatically adjust its high- and low-frequency filters to automatically eliminate non-listening noises such as those generated by demolition tools, vehicles, wind, and high-voltage cables.

3. Voice Intercom Probe: The voice communication probe has a diameter of 44 mm and is equipped with an extremely sensitive, omnidirectional audio vibration sensor, as well as a microphone and a speaker. It can be easily inserted into the holes drilled by the perforator, enabling two-way voice communication between rescuers and survivors.
