Local area network structure of the paired lines twisted by a certain data torque, referred to as: UTP 
 Twisted pairs of wire away from the electromagnetic radiation and external electromagnetic interference have different data in different ways, so the UTP different electrical characteristics, so the twisted pair to be classified according to their electrical characteristics. 
 Application: 
 Applies to the information network video office to use cable connection, families, schools, shopping malls, public places, government. 
 Wiring mode: 
 Wiring the way there are many, the best way to wiring is consistent with the engineering wiring Therefore, we according to the circumstances of the project in several ways combined use. 
 1, point to point. Each monitoring point, the super-class line of the four core pull a cable or a 2 if this needs to pass control signals, it can take two pairs of the remaining lines to transmit the control signal. 

 2, the first-line string. Every four monitoring points to pull a cable, wiring first annex four divided into an area this one cable distance order through these four points, a point to poke the skin to remove the one on the line for the way the camera to use. 
 3, the first concentration, and sent. The first camera signal through the coaxial line together, and into the multi-channel transmitter after transmission through a network cable back to the monitoring center. 
 4, the tree structure. Signal of the monitoring points will be distributed by the two pairs of 4-core twisted pair pulled a relatively concentrated, and then 4 or a large number of super category 5 twisted pair back to the monitoring center. 
 All of the above wiring connection must be with welded connections, welded to wrap up, to prevent water and oxidation. 
 Shenzhen City, Endeavour reached Communication Technology Co., Ltd. is a specialized set of security and intelligence weak cable R & D, production and sales network cables, video cables, control (no) sheathed cables, control shield cables, building intercom lines, phone lines, audio cable, single core multi-strand wire and other security wire for a modern integrated enterprise.
