Product introduction:
Russian ImportsBDA-3 audio shield has advanced interference mode, not only has the ultrasonic transmitter, but also has a powerful analog voice noise generator. The combination of ultrasonic and noise generators can interfere with any equipment with microphone pickup, such as attenuated digital recording pens, eavesdroppers, mobile phones, wired, wireless microphones, etc.
BDA-3 product itself is equipped with seven ultrasonic emitters (there are two ultrasonic emitters above the product panel and five ultrasonic emitters on the side) and can optionally be equipped with external ultrasonic emitters (two groups can be connected, one group has four ultrasonic emitters). The emitter location of external ultrasonic emitters can be adjusted, and the interference ability is stronger.
