What is the difference between a recording jammer and a signal jammer?
The principle of the recording signal jammer for phone is to produce suppressive interference to the speech signal through random sound wave signals, so that the digital recording equipment only has noise information and cannot distinguish the speech signal. Through randomly generated sequences, the original information cannot be restored from the recorded signal, thus ensuring the security of voice information. This product only blocks recordings from mobile phones and voice recorders.
Signal blockers are relatively broad. Mobile phone signals, WIFI signals, walkie-talkie signals, GPS signals, remote control signals, etc. are all types of signals. This type of jammer interferes with normal signal reception through the frequency signal it emits, such as a mobile phone. The principle of the signal jammer is to scan from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. This scanning speed can cause garbled interference in the message signals received by the mobile phone. The mobile phone cannot detect the normal data sent from the base station, making the mobile phone unable to establish a connection with the base station, thereby blocking the mobile phone signal.
