In order to meet the requirements of new trends, improve the high-tech prevention level of prisons, improve the high-tech management capabilities of prisons, promote the establishment of data information management detention centers, promote the harmonious and stable progress of prisons, and continue to improve the modern level of prison operations, requiring mobile phones in prisons The signal carries out reasonable and reasonable manipulation and prevention to avoid security risks arising from the use of smartphones in violation of regulations.
The construction of a smart phone signal shielding system in the prison follows the relevant regulations and directives of the Ministry of Justice of the State, and also has practical and urgent requirements. In the operation and maintenance process of the prison smart phone signal shielding system, for the interception of the internal area of the building, it is necessary to fully consider the distance between citizens (colleges) and other public facilities near the building location, and also refer to the distance and receiving sensitivity of the communication base stations of nearby communication racks. , In order not to affect all normal communications of mobile phone signals in nearby public facilities to carry out network interception.
In addition, it is necessary to take into account the regulations on the full coverage of mobile phone signal interception within the prison area. Outdoor large-scale shielding devices can be used to cover the courtyard wall inward to ensure the interception of mobile phone signals in all areas. The existing blind spots and missing points are used to assemble the mobile phone signal jammer, and then make full use of the product characteristics to further improve the role of the jammer.
Smart cell phone jammer product features:
1, 6-channel cross-type interception, to achieve the best interception effect, interception includes GSM, CDMA, DCS, PHS, TD-SCDMA, CDMA2000, WCDMA, 4G
2. Reasonably divided into stages, which only affects the downlink and does not affect the communication base station;
3. The display lights on the overall fuselage are convenient for the suspension height to be higher than the field of view, and the interception work can also be grasped according to the lower display lights.
4. Imported processing chips, guaranteeing quality, quantity and reliability;
5. The power supply is embedded to prevent criminals from deliberately destroying it and ensure the equipment lifespan;
6. Two-way metal material industrialized switching power supply, which can complete uninterrupted and sustainable operation in a true sense;
7. The mobile phone signal jammer is a small output power device, which is environmentally friendly, safe and reliable, and does not pose a threat to health.
