Why does the detention center install a mobile phone signal shielding system?
In recent years, the cell phone signal jammer system, as an important part of the digital construction project of the detention center, has been accepted and installed by many detention centers, and has been well applied in the system. Maybe some people will have doubts. Isn’t the criminal suspect detained in the detention center not allowed to carry mobile phones from the first day of entering the detention center? Since the criminal suspect does not have a mobile phone, why does the detention center install a mobile phone signal shielding system?
According to the normal detention system of the detention center, the criminal suspect's mobile phone and some other personal prohibited items will be temporarily confiscated from the first day of his detention, and these items can only be returned when he leaves the detention center in the future. From this point of view, under normal circumstances, it seems that there will be no mobile phones in the detention center. If you don't have a mobile phone, installing a mobile phone signal blocking system is a bit redundant.
However, this is not the case in reality, because in a prison like a detention center, in addition to the detained criminal suspects, there are at least: prison guards who supervise the criminal suspects, chefs, doctors, maintenance workers, etc. who maintain the normal operation of the detention center. staff etc. Among these personnel, there are many individuals who evaded or bypassed the supervision system of the detention center out of selfishness, and brought their mobile phones into the detention center without permission. What's more, it is possible to hand over the privately brought mobile phone to the criminal suspect for use.
Once the criminal suspects have obtained the mobile phone, they will use the mobile phone to contact the outside world secretly. What kind of consequences will this have? From previous news reports, we can know that in the past, after criminal suspects communicated with the outside world through privately hidden mobile phones, vicious incidents occurred frequently. Malicious vengeance against enemies and more. From this point of view, the purpose of installing a mobile phone signal shielding system in the detention center is to prevent and prevent criminal suspects from using mobile phones to contact the outside world, so as to truly isolate them from the outside world.
Finally, let’s talk about another question: Does the mobile phone signal shielding system installed in the detention center need to achieve 100% complete coverage? the answer is negative. In fact, it is possible to divide key areas for key prevention. For example, the mobile phone signal shielding system should focus on some hidden places and relatively small spaces that are easy to avoid crowds and be alone. For example, some public halls, outdoor playgrounds and open areas, as well as places where surveillance can directly monitor, etc., do not need to be used as key prevention areas or even consider installing mobile phone signal shielding systems, because criminal suspects will not be blatantly in public places or surveillance The camera is down to openly use the phone.
