For SWAT operations, the PKI 2370 Wireless Super Stethoscope, stereo offers the best technical monitoring option meeting the highest demands regarding eavesdropping through walls, doors, ceilings. No conversation remains undetected. Within seconds both sound sensors are attached to the object to be monitored using our special adhesive. In most cases, these are walls, windows or door frames. The distance to the sound sensor can be optionally chosen from 20cm to 2m. The sound waves are recorded independently by both special piezo elements and are multiplied up to 30,000-fold by the built-in low-noise amplifier. A potentiometer of the respective sound sensor enables the optional sensitivity adjustment from high to low and on/off. The sound sensor with the integrated broadband HF transmitter transmits the recorded signals to our special stereo headset with built-in receiver within 100m. An additional PKI 2105 recorder can record these on request. Exterior noise, caused by vehicles, etc., is eliminated by the closed headset system.
