Smart Prison Communication Signal Jamming Control System Prison Mobile Signal Jammer

Overview
The system equipment adopts digital base station technology and computer intelligent management and control technology, the system only needs to reach the signal field strength equivalent to the traditional base station and enable effective mobile signal control of coverage areas, the electromagnetic radiation of the personnel in the coverage area is far less than the radiation standard stipulated by the state, and will not cause long-term radiation damage to the human body. The system consumes a significant amount of electricity, which is also called green shielding.

Shielding area mobile phone manange and control, at the same time, combined with the passive antenna feed distribution system, uniformity wireless signal coverage is performed on the required shielding area. It can effectively control the external signal leakage, and implement bundled communication blocking for illegal mobile phones in the coverage area. There will be no blind spots and dead ends, and no signal interference will be caused to the surrounding normal mobile phone users and carrier base stations.

Can set whitelisted mobile number in the system, ensure that the prison guards mobile phone normally working, while in blocking area effective shielding illegal mobile phone with the surrounding base station communication, through mobile phone number intelligent indentification tehnology, the user of the preset mobile number can be kept in normal communication with the original base station.

When the system is in communication and computer intelligent identification control, obtained the serial number, sim card number or feature number in the effective control area, intercept the text message sent by the mobile phone and the dialed phone number, and also in the control center can send  fraudulent messages such as" network busy" or " Dial-out usrs not in the service area" to the specific mobile phone in the caverage area, and thus provide a powerful means for the prison administrators to timely grasp the information of criminal activities and prevent crimes.

It can carry out large-area and high-efficiency search work on the confidential areas that are prohibited from entering the mobile phone, and realize the functions of shielding, locating, and grabbing the searched mobile phones, cause hidden trouble and danger to secret safety. The system is mature and will not interfere with the normal operation of the communication network.

The basic functions of the system include:

1. According to different communication system of in all coverage areas to terminal uers IMSI capture
2. To captured IMSI filtering whitelist and blacklist
3. Whitelist users release back to the macro network for normal communication.
4. Not Whitelist user communication blocking and shielding
5. Conduct communication monitoring for blacklist users who meet certain conditions, Or with other device for positioning
6. 20W coverage distance directional antenna jamming diameter 1000-2000M, omnidirectional antenna jamming radius 500-800M.
7. The detailed functions of the various communication systems included: Macro network scanning, Automatic and manual network settings, IMSI / ESN capture, Black and white list setting and filtering, Access policy configuration, In the network UE status monitoring, Report terminal signal strength.
8. For TDD-LTE and FDD-LTE, the captured UEcan be redirected to the specified 2G and 3G systems.

MOSO UFO High Bay LED Driver have the character of high power factor, high efficiency, high reliability and high-precision constant current. The UFO led driver owns a complete of function, various specifications can meet more different parameter of customers` requirement.

                                                     

MOSO Intelligent innovator UFO shape led power has the led driver industry ' s unique derating over temperature protection circuit , which can make the light power supply not easy suddenly happen the phenomenon of over - temperature and shutdown even under the harsh working environment , so as to ensure continuous illumination.

The efficiency of the led driver supply is high and the power consumption is small. Accordingly, the heat in the lamp is small, then it reduce the temperature rise of the lamp. It is more advantage to delay the light decay of LED.

This Circular high-bay lighting drivers creatively integrated limited power, 0~10V/PWM dimming, dali control is optional.

Dali Industrial Light LED Driver complied with CCC/CE/ENEC/UL/SAA/CB safety regulations. Surge immunity is DM-4KV,CM-6KV.
