| ed pair video transmission devices is the use of | | | | Technology twisted pair transmitter. |
| five types of network cable instead of coaxial | | | | 2) to facilitate wiring, cable high utilization. A pair of |
| cable, twisted pair video transmission equipment, | | | | ordinary telephone lines can be used to transmit |
| use inexpensive, easily drawn more than five or | | | | video signals. In addition, the building blocks laid in a |
| five unshielded twisted pair (UTP computer | | | | wide range of Category 5 unshielded twisted-pair |
| network cable) four pairs of wire in the way a | | | | get one pair in any way you can transmit video |
| pair of wire transmission of high-quality video | | | | signals without additional wiring, even the re-wiring, |
| signals, the other twisted pair cable that can be | | | | Category 5 cable is also easier than coaxial cable. |
| used to transmit audio signals or control the head | | | | In addition, a Category 5 cable has 4 twisted pair, |
| of the RS-485 data, but also can transmit more | | | | if you use a pair of lines to carry video signals, |
| video signals, and signals no interference between | | | | while a few of the lines can also be used to |
| the transmission distance of 0 to 1,500 meters | | | | transmit audio signals, control signals, power |
| optional. Not only solve the security and video | | | | supply, or other signals, to improve the line cable |

| distortion and in complex industrial environments | | | | 3) anti-jamming capability. Twisted pair can |
| electromagnetic video Ganrao , but also greatly | | | | effectively suppress common mode interference, |
| save the Xianlu , construction and maintenance | | | | even in strong interference environment, the |
| becomes very easy, Cheng Wei video monitoring | | | | twisted pair is also an excellent image signal can |
| project in addressing the 1-3 km long distance | | | | be conveyed. Moreover, the use of a twisted pair |
| transmission issues in one of the most economical | | | | cable in a few of the different signals are |
| and practical approach. | | | | transmitted, interference will not occur between |
| The use of twisted-pair long, in many industrial | | | | each other. |
| control systems and interference in larger | | | | 4) high reliability, ease of use. Use of twisted pair |
| establishments as well as long-distance | | | | transmission video signals, in the front end to |
| transmission of a twisted pair is used, we also | | | | access special transmitter in the control center to |
| used widely used LAN twisted pair right. The | | | | access special receiver. This twisted pair |
| reason why such a broad use of twisted pair, | | | | transmission equipment cheap, very easy to use, |
| because of its strong anti-interference, | | | | no expertise, nor too many operations, once |
| transmission distance, cabling is easy, inexpensive, | | | | installed, long-term stability. |
| and many other advantages. Twisted pair of | | | | 5) The cheap, easily obtained. As is widely used in |
| signal attenuation there are large, twisted pair | | | | ordinary Category 5 unshielded cable, easy to |
| video signal directly within the transmission if the | | | | buy, and the price is very cheap, to engineering to |
| will decay much, so the video signal on the | | | | bring great convenience. |
| twisted pair to achieve the long-distance | | | | Twisted pair video transmission devices is the use |
| transmission, the need for amplification and | | | | of twisted pair transmission video signal is only in |
| compensation, Twisted pair video transmission | | | | recent years the rise of technology, generally |
| devices that accomplish this function. Plus a pair of | | | | refers to the so-called twisted-pair cable, twisted |
| twisted pair video transceiver equipment, images | | | | pair transmission using differential transmission |
| can be transferred to the 1 to 2km. Twisted pair | | | | principle, in the video signal transform transmitter |
| and twisted pair video transmission equipment | | | | into the same magnitude, opposite polarity video |
| prices are very cheap, not only does not increase | | | | signal, after transmission through twisted pair, at |
| the system cost, but the distance increases the | | | | the receiving end will be two polar opposite of the |
| cost compared with coaxial cable down a lot. | | | | video signal subtraction into the usual video signal, |
| Therefore, security monitoring, multimedia | | | | it can effectively suppress common mode |
| network teaching system using twisted pair for | | | | interference, even in the strongly interference |
| transmission and so has obvious advantages: | | | | environment, its good anti-interference capability |
| 1) The transmission distance, transmission of high | | | | than coaxial cable, and video signals through the |
| quality. As in the twisted pair transceiver uses | | | | processing, the transmission of video signals |
| advanced processing techniques, to best | | | | clearer than coaxial cable, with a network cable |
| compensate the twisted pair video signal | | | | between interference will not occur. |
| amplitude attenuation and the attenuation | | | | Advantages 1, to facilitate wiring, cable high |
| difference between different frequencies, | | | | utilization. A common network of over five lines, |
| maintaining the original image brightness and color | | | | there are four pairs of twisted pair, can also |
| as well as real-time, the transmission distance of | | | | transmit 4 video signals, or 3-way video, 1 channel |
| up to 1km or longer, the image signal almost no | | | | control signal; better than coaxial cable and cable |
| distortion. If using relay mode, the transmission | | | | laying. |
| distance will be longer. For example: You Trump | | | | |
