The "DAudio BDA-2" anti-tapping jammer produced in Russia can solve your worries. Anti-recording and eavesdropping jammer is a portable and highly integrated security protection device, which integrates ultrasonic interference and voice acoustic interference. It can effectively interfere with digital analog recording such as recording pen, mobile phone recording and tape recording, and interfere with various voice eavesdroppers such as wireless eavesdropping, wired eavesdropping, partition eavesdropping, laser eavesdropping, etc. To make the voice of the eavesdropper's conversation unrecognizable, so as to effectively protect your privacy.
At present, there are few kinds of anti-recording and eavesdropping products at home and abroad, but only through noise to shield interference. Although there is some interference effect, the effect of interference shielding recording and eavesdropping is not ideal, and some of them use ultrasonic interference, but the volume is large, the interference distance is close, the working time is short, and the carrying is not good. It is convenient, and the efficiency of single interference shielding is less than 60%. "DAudio BDA-2" anti-audio eavesdropping jammer adopts ultrasonic directional jamming, low power consumption, long distance, voiceprint canceling sound wave interference power adjustable, low frequency interference is adopted to reduce the impact on conversation, external speaker effect is better, the effective rate of ultrasound and voiceprint interference is 100%.
