雙絞線傳輸器的接法有很多種,而不同的布線工程,所採用的雙絞線傳輸器接法也會有不同,下面我們一起來看看雙絞線傳輸器的接法有哪些?
雙絞線傳輸器的接法
1)點對點
每一個監控點拉一條網線或者一條2對四芯的超5類線,如果這個點需要傳控制信號,就可以拿這2對中剩餘的線來傳輸控制信號。
2)一線串
每四個監控點拉一條網線,布線時先將附件四路劃分到一個區域將這一根網線按遠近順序經過這四個點, 每到一個點就撥開外皮取出其中一對線供一路攝像機使用。
3)先集中,後發送
先將攝像頭的信號通過同軸線集中到一起,進入多路發射器後再通過一根網線傳輸回監控中心。
4)樹型結構
利用2對4芯的雙絞線將分散的監控點的信號拉到一個相對集中的地方,然後通過4對或者大對數超5類雙絞線拉回監控中心。

Twisted pair transmitter connection
1) Point to point
Each monitoring point to pull a network cable or a 2 pairs of four-core ultra-Category 5 line, if this point needs to pass control signals, you can take these two pairs of the remaining lines to transmit control signals.
2) First-line string
Every four monitoring points to pull a network cable, the first four lines of attachment will be divided into an area of the network cable in accordance with the order of the four points, each to a point to remove the outer one pair of cable for all the way cameras use.
3) Focus first, then send
The first camera signal through the coaxial cable together, into the multi-channel transmitter and then transmitted back to the monitoring center through a network cable.
4) Tree structure
Using two pairs of 4-core twisted pair cables, the signals of the scattered monitoring points are pulled to a relatively concentrated place, and then pulled back to the monitoring center through 4 pairs or over a large number of over Category 5 twisted pair cables.
