First of all, thank you for reading the system profile. WS-4 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 mainframes, each with four signal transmitting terminals and stepless power adjustment knobs. The two sets of mainframes are simultaneously opened and arranged around the illegal recorders to achieve recording shielding.

In order to ensure the shielding effect, the system is based on two sets of shielding hosts, which can not be less than two, but can be increased by one. Each host software adopts a mute encryption algorithm based on logo, which ensures that recording files can not be decoded and decomposed. This algorithm is widely used in mobile phone data encryption and is extremely safe. Silence adopts adaptive silencing technology, which ensures the concealment and security of visitors without any discomfort after booting.

WS-4 has a good shielding effect on the latest mainstream mobile phones on the market, such as MATE20, P20pro, and iPhone X/XR/XS/XSMAX.

The double swords are all the rage for illegal recordings.

System characteristics:

1. Flexible use, two sets as a basic configuration, can flexibly increase the host according to the scene, to achieve better shielding effect.

2. Flexible operation, remote control can be used to open and close multiple sets of mainframes at the same time.

3. Flexible configuration, each host can work independently, flexible layout, arbitrary placement, a key to start.

4. Flexible and portable, each host is equipped with batteries, easy to use

5. Adaptive silencing technology ensures quietness in use.

6. Output effective power is over 98%.
