Audio (Sound Vibration) Life Detector
Brand: Beijing Shengbolan
Model:BF-20R
Audio life detector, also known as acoustic vibration life detector, is an acoustic detector used to detect and locate survivors buried in collapsed structures due to earthquakes, explosions, landslides, mine accidents or building depressions. Audio life detectors can detect these life signals through special sensors that sense tiny vibrations.
Product Advantage
*Integrating two highly sensitive omnidirectional audio vibration sensors, extremely weak sound can be picked up.
*Each sensor is equipped with8Meter cable, wider detection area
*Equipped with professional noise reduction monitoring stereo headphones, can effectively avoid external noise interference.
*Host equipped5.6An inch color LCD screen can display the image, and a video probe can be used to locate the trapped person accurately when the trapped person is detected.
*Sensors equipped with integrated speakers, microphones and infrared video probes can communicate with the trapped and transmit video images.
*Wide range of frequency detection40～3000HZ
*Video detection using hand-held probes, length5Mi, can be manually bent and shaped, and180Degree reversal, wider detection range and larger angle
*The probe type isCMOSImage sensor, equipped with6SeedLEDSupplementary lamp with adjustable brightness
*Probe waterproof, protection levelIP67
