With the rapid development of communication technology, mobile phones have become the main tool for information dissemination. However, in high-security places such as prisons and detention centers, the abuse of mobile phones may bring serious security risks, such as:
Prisoner illegal communication: Contacting external accomplices, planning prison breaks and criminal activities.
Information leakage risk: Illegal recording, video recording or transmission of confidential information.
Fraud crime: Some prisoners use mobile phones to carry out telecommunications fraud, causing social harm.
To effectively prevent illegal communication within prisons, prison signal shielding equipment has become an essential security measure in modern prison management.
First,Working principle
Prison signal shielding equipment adopts radio interference technology. By emitting interference signals of specific frequency bands, it covers the target area and prevents mobile phones from working properly. Its workflow is as follows:
Signal detection: Use signal detection equipment to scan the mobile phone signal frequency bands within the prison area, such as 2G/3G/4G/5G.
Interference shielding: Shielding devices emit radio signals of the same frequency as mobile communications, interfering with the connection between mobile phones and base stations, leaving them in a "no signal" state.
Automatic adjustment: Intelligently adjust the shielding power based on the signal strength of different areas to ensure complete coverage within the prison while avoiding any impact on normal external communication.
Remote monitoring: The shielding equipment can be remotely managed through the monitoring system, and the shielding status can be monitored in real time to ensure the normal operation of the equipment.
Second, functional features
Full frequency band coverage: Supports multiple signal shielding including 2G, 3G, 4G, 5G, WiFi, Bluetooth, etc., to prevent any form of illegal communication.
Intelligent adjustment: The shielding range can be adjusted according to the prison environment to avoid interfering with the surrounding legitimate signals.
All-weather stable operation: With industrial-grade design, it supports 7× 24-hour continuous operation and is suitable for complex environments such as high temperature and high humidity.
Remote control and monitoring: It can be remotely controlled via the network, allowing real-time viewing of the equipment's operating status and enhancing management efficiency.
Directional shielding: By using directional antennas, the signals within the prison area are precisely shielded without affecting the normal communication of the surrounding residents.
Anti-cracking design: The device is equipped with security measures such as anti-interference, anti-cracking, and anti-bypass to ensure the long-term stability of the shielding effect.
Third, application scenarios
Prisons and detention centers: Prevent prisoners from illegally communicating via mobile phones to ensure prison security.
Detention center: To prevent detained individuals from illegally contacting the outside world and affecting case investigations.
The military and confidential agencies: Ensure the information security of military bases and intelligence departments, and prevent the leakage of confidential information.
Examination rooms and confidential meetings: Prevent candidates from cheating with mobile phones to ensure the fairness of the examination; Block signals during the meeting to prevent information leakage.
