There are relatively blind spots in the management of prisoners in prisons and detention centers, and high-tech jailbreaking methods are no longer a storyline that appears in American blockbusters. Inmates use mobile phones and other communication tools to communicate with the outside world, and there have been several cases of escape from prison in China. What's more, some police officers provide mobile phones for prisoners to use, and the charging of communication fees is not new. How to put an end to this phenomenon has become a difficult problem facing the prison management department. In order to eliminate this phenomenon, prisons in some provinces have decided to install cell phone signal jammers in the prison area to eliminate this problem. So, what issues should be paid attention to when the prison system chooses a mobile phone signal jammer?
The choice of barriers in the prison system should be considered from the following aspects.
一: The prison system has special requirements for the use of jammers. The jammer must be able to meet the requirements for perennial startup. This requires that the selected shielding device has the characteristics of suitable power, good heat dissipation and stable performance.
Two: High gain and strong signal penetration are also required. Due to the particularity of the prison system environment, the walls of the general prison area are relatively thick, and mobile phone jammers must have good gains. The penetrating power is relatively strong, so it is recommended to use a shield with an external antenna.
3: It is conducive to maintenance and inspection, and prevents prisoners from sabotage. Prisoners are a special group. After the shield is installed, it is very likely to be damaged quickly, such as unplugging the power supply and other destructive methods, so you need to pay special attention when installing it.
