The Importance of Prison Signal Jammers in Ensuring Security

Installing Prison Signal Jammers: A Crucial Step in Preventing Illegal Communication

Prison signal jammers are indispensable devices within correctional facilities. Their primary function is to block cellphone signals, rendering them ineffective. As it is widely known, inmates are prohibited from using mobile phones for communication. However, it is still inevitable that some prisoners manage to smuggle phones into the facility, enabling them to continue engaging in criminal activities. This article explores the installation process of prison signal jammers and highlights their significance in maintaining security within prisons.

Ensuring Effective Installation:

Installing prison signal jammers in correctional environments can be challenging due to the complex nature of the facilities. With numerous thick cement walls, it becomes crucial to increase the number of signal jammers to enhance signal penetration. Determining the approximate installation quantity becomes possible by assessing the length and width of the designated signal-blocking areas within the prison.

Optimizing Signal Coverage:

To achieve optimal signal coverage, it is recommended to install the signal jammers at a height ranging from 1.8m to 2.5m. This height range has been found to yield the best results. In cases where blind spots are identified during the installation process, the use of high and low-power prison signal jammers in combination can effectively resolve this issue.

Thorough Inspection and Power Connection:

After the installation is complete, it is essential to conduct a thorough inspection to ensure all components are properly connected. Subsequently, the power cord should be directly plugged into a 220V socket. In the event of any issues or concerns, prison authorities can promptly contact our team for immediate assistance and resolution.


The installation of prison signal jammers plays a vital role in preventing illegal communication within correctional facilities. By effectively blocking cellphone signals, these devices contribute significantly to maintaining security and preventing criminal activities. The complex prison environment necessitates careful consideration of the number and placement of signal jammers to ensure optimal coverage. With proper installation and regular maintenance, prison authorities can effectively combat the illicit use of mobile phones by inmates, thereby enhancing the overall safety and security of the facility.
