Secrecy agency needs hand signal cellphone jammer

　　Every day we use mobile phones to find signals, why do we need signal cellphone jammers? In fact, there are two aspects of this fact. For those who can use mobile phones, of course, they hope that the stronger the mobile phone signal, the better. However, for prisoners, secret units and other special places, of course, it is necessary to effectively interfere with the mobile phone signal in order to do a good job of security and absolute confidentiality.

　　Take the prison as an example. For the prisoners detained here, it is a must to keep contact with the outside world. Otherwise, how to accept the transformation with peace of mind. In addition, there is no mobile phone signal. Even if you have a mobile phone in your hand, you cannot communicate with the outside world. Reduce the occurrence of inappropriate things such as escape.

　　However, there are still many staff in the prison. They need to have normal contact with the outside world and accept the leadership of higher-level units. Their external contact is a must, and this is also their right. Here, the signal cellphone jammer can be used to effectively and targetedly shield the mobile phone signals in the areas that should be shielded, such as prison cells, etc. In addition, the signals in other places can be normal.

　　For some enterprises and institutions that require a high degree of confidentiality, it is also necessary to use selective GPS jammers to open some signal areas and close some areas, so as to prevent the occurrence of secret theft. Although the use of mobile phone signal shielding system is a small-scale market demand, this market cannot be ignored, and shielding work must be done to ensure the normal operation of this organization.
