Cell phone jammer intelligent system can be achieved

Thus a very limited distance transmission lines, has also decided to transmission system users and large ones can not be too much. ? Holds cables and more programs for access trouble. ? Anti-interference ability. Coaxial cable shield for shielding the signal frequency, the lower the worse the performance, so vulnerable to carrier telephone, cable radio, audio, communications and other signal interference. If using overhead open-wire cable for the antenna when the effect will be a frequency of 500KHZ ~ 1600KHZ medium wave radio signal interference. The detector of  cell phone blocker intelligent system will send the abnormal monitoring information to the corresponding PC.RF signal transmission is the high-frequency RF and audio signals are modulated carrier signal, making our standard television broadcast signal (RF signal), and then sent to the trunk cable transmission, and video transmission compared with the following characteristics. ? Equipment complex, demanding match. To increase the transmission frequency converter. As the carrier frequency is high, prone to mismatch reflection (VSWR), causing the user when viewing the image ghosting, so the required equipment and devices, equipment and cables should be connected between the impedance matching to ensure the quality of image transmission. ? Easy to compete with the local television program channels. RF transmission cable system is mainly used, multiple cable system is modulated RF signals in different channels are mixed together, through a coaxial cable or fiber optic transmission to different users to watch. PC of  cell phone jammer intelligent system will record the information for the future inquiry through the pre-installed net line.The system is easy to compete with radio and television channels, but can be used by the occupation of the local air channels to be addressed by specific methods to determine the channel modulator. ? Long distance transmission system capacity. You can use the same cable as multiple programs, the amplifier in the trunk transmission part of the installation after the extended transmission distance to several kilometers. So save a lot of cables and carry more users. ? Increase the program easy to transform the content simple. When the program is increased without changing the line and additional equipment, just part of the increase in front-end mixed all the way input interface can be realized. Just press the TV channel reception converter to receive the increase after the program. ? Easy to network with the network and the outside world. In summary, the RF transmission and video transmission are the two closed-circuit television signal transmission system, according to the different forms of transmission can be divided into two major types of cable and TV applications. In many occasions, and both can be combined together to form a multi-functional integrated CCTV systems. Third, the application type and direction of television's A TV application TV application of the classification system used by general departments, the use of environmental classification.When the delay time reaches,  cell phone jammer  will be automatically shut down.
Purpose of intelligently eliminating the negative effect caused by the cell phone through cell phone jammer intelligent system can be achieved.  A common industry TV mainly used for industrial production, testing, research and other on-site monitoring. After installation can improve efficiency and ensure safety, improve the working environment. Two teaching television electronic teaching has gradually been recognized and accepted, and gradually spread. Electronic teaching intuitive, vivid, strong infection, etc. so that students understand the deep memory of prison, to help speed up the progress of teaching and improve teaching quality. While reducing the labor intensity of teachers, saving teachers and teaching equipment. Three medical TV application TV system in the medical field has broad prospects for development. It is not only for general medical care, but also with other electronic medical device for pathological examination and treatment.
