Audio life detector

Audio life detector

Brand: Sheng Bolan

Model: BE-50R/2000

An audio life detector is an acoustic detection device designed to detect and locate victims following earthquakes, explosions, and... Landslide Survivors of mine accidents or building collapses who are buried beneath collapsed structures. Life detectors can detect subtle vibrations through specialized sensors. Sensor Detecting these life signals allows for precise localization of trapped individuals; the probe boasts high sensitivity.

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 rescue operations in rubble caused by earthquakes, collapses, and building collapses, applicable to... Firefighting Municipal, mine rescue, and other emergency response agencies carry out rescue operations in confined spaces and areas that are difficult to reach using conventional methods—for example, providing feedback on the conditions of victims trapped in collapsed buildings, deep wells, mines, and other confined spaces; locating missing persons in damaged vehicles, aircraft, ships, and trains—especially in areas that are hard to see 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 user manual. The host supports voice broadcasting, recording, and playback functions. It features a waterproof design, allowing it to be used even in harsh weather conditions.

2. Audio Sensor: The device is equipped with four wireless sensors (expandable to six or eight channels). The audio detection range is 20 meters. The audio sensor features high sensitivity and a detection frequency of 0–5,000 Hz. It can automatically adjust high- and low-frequency filters to automatically eliminate non-listening noises such as those from 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 holes drilled by a perforator, enabling two-way voice communication between rescuers and survivors.
