Optical/Acoustic Dual-Mode Life Detector

Acoustic/Optical Dual-Mode Life Detector

Brand: Sheng Bolan

Model: BE-20R/2000

The optical/sonic dual-mode life detector is a rapid search-and-rescue system that integrates vibration signal detection, video imaging, and the ability to communicate directly with trapped individuals. Powered by a specialized microelectronic processor, this device can detect even the tiniest vibrations propagating through air and solid materials, making it ideal for locating survivors buried beneath concrete slabs, rubble, and other solid structures. It accurately identifies sounds emitted by survivors—such as shouts, hand claps, scratches, and knocks—and simultaneously filters out background noise from the surrounding environment. After a disaster, the search for survivors is a race against time. The life detector helps rescue teams pinpoint survivors who are signaling for help by moving, tapping, or calling out. Equipped with a rotating camera, this device can operate even in completely dark environments. Moreover, it allows for quick switching between audio and video search modes on the same unit, significantly reducing search-and-rescue time and greatly increasing the chances of survival for those trapped. As a result, this device has gained widespread popularity among rescue teams worldwide. It is particularly well-suited for post-disaster rescue operations following earthquakes, bombings, and explosions inside buildings—whether caused by gas leaks or deliberate acts.

1. Color LCD display with a diagonal length greater than 25 cm and equipped with a sunshade;

2. Two-way voice intercom, with support for recording and broadcasting functions.

3. Equipped with a wireless receiver and featuring third-party display functionality, enabling on-site leaders to remotely command and dispatch operations.

4. Voice-controlled rotating probe: Controlled by the host, it features 360-degree rotation and 180-degree flipping. It comes with a built-in fill light for use in dark environments, offering a night vision range of over 6 meters. The probe is equipped with a built-in microphone and speaker, supporting two-way intercom communication.

5. Equipped with four-channel audio vibration sensors, the vibration signals are displayed as bar graphs.

Primarily used in earthquake rescue, it can record underground sound waves and detect even the slightest vibrations in rubble—such as shouts, slaps, scratches, and knocks. It can also filter out surrounding background noise, helping rescuers pinpoint the location of survivors who are calling for help.

1. Host: Equipped with an extra-large 10-inch LCD display featuring a diagonal length of 25 cm, the host can convert vibration signals detected by up to four vibration sensors into bar graphs and display them on the screen. The bar graph display allows users to distinguish between different signal sources. A professional filter effectively eliminates surrounding background noise, providing robust shielding against noise generated by heavy trucks or other heavy machinery at rescue sites.

2. Audio Vibration Sensor: Number of audio vibration sensors: 4 channels; cable length: 10 meters;

3. 360-degree rotating probe: The probe features a built-in microphone and speaker, enabling two-way intercom communication. Intercom signals can be transmitted to the host unit or a wireless receiver, and real-time voice communication with trapped individuals is possible via noise-canceling headphones.

4. Audio and video wireless receiver: LCD display, equipped with a screen sunshade, featuring an output interface for connecting an external display.
