Ws-3 defender is a kind of enhanced recording shield system developed by our company according to the market demand. The product is economical, applicable, price friendly and flexible to use. It is suitable for all kinds of small private conversation places. It can be placed arbitrarily according to the actual situation of the place. It is extremely convenient (such as car, small conference room, negotiation area, office, etc.).

The Ws-3 defender is composed of a shielder host and an expander (two). Each expander is equipped with four signal transmitting terminals, which are wired to the host. It can be flexibly arranged around the illegal recorder to form a shielding network. It can achieve back-to-microphone shielding and 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. Silence adopts adaptive silencing technology, which ensures the concealment and security of visitors without any discomfort after booting.

WS-3 has a good shielding effect on the latest mainstream mobile phones on the market, such as MATE20, P20pro, XR/XS/XSMAX and so on.

Special attention: If the shielding effect of this recording shielding system is not ideal for individual recording equipment, it is suggested to use two sets to solve this problem.

Ws-3 mainframe and expander shell adopt injection moulding technology, which is compact, beautiful and generous in appearance. The size of the mainframe is the same as that of the adult hand. The expander is 1/2 of that of the adult hand. It is light in weight and easy to carry.
