RecordingShielding System WS-4
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. 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
