Audited Supplier The "Concealed" Recording Shield is a highly integrated high-tech security product developed by AL ASAR TECH. When a criminal uses a recording device (such as a mobile phone, voice recorder, recorder, etc.) to record you, the recording mask produces a random noise signal that can suppress the interference of the voice signal, so that the recording device can only pick up Noise information, and can not distinguish voice information, thus ensuring the security of voice information.
