First of all, thank you for reading the system profile. WS-4 ultrasonic audio recording shielding system is a new type of recording shielding system developed by our R&D team in combination with our existing products and customer needs. It consists of two sets of ultrasonic audio recording jammers, each with four ultrasonic transducers and power adjustment knobs. When you open the two sets of jammers simultaneously, it can achieve a better audio recording shielding effect.

In order to ensure the shielding effect, the basic configuration of the system is two sets of ultrasonic audio recording jammers, which can not be less than two, but can be added. The software of each jammer main unit adopts a silent encryption algorithm based on identification, which ensures that the recording file can not be deciphered and decomposed. This algorithm is widely used in mobile phone data encryption and is extremely secure. Self adaptive mute technology is adopted to ensure the invisibility and security of visitors without any discomfort after turning on.
