Ws-5 type defender is an enhanced recording shield system developed by our company according to the market demand. This system consists of shielder host and expander. The host is equipped with five signal transmitting terminals and the expander is equipped with four signal transmitting terminals. The two terminals are wired and arranged around the illegal recorder to form shielding network, which can realize back-to-back interference to the microphone. To achieve the best shielding effect.

The software adopts the mute encryption algorithm based on identification, which is widely used in mobile phone data encryption and is extremely safe. It ensures that the recording files can not be decoded and decomposed. The mute adopts adaptive mute technology, which guarantees concealment and security without any discomfort to visitors after booting.

WS-5 has a good shielding effect on the latest mainstream mobile phones on the market, such as MATE20, P20pro, XR/XS/XSMAX and so on.

Ws-5 mainframe and expander shell adopt one-time injection molding technology. The appearance is compact, beautiful and generous. The size of the mainframe is the same as that of the adult hand. The expander is 1/2 of the adult hand. It is light in weight and easy to carry. Look at the parameter table in detail.
