Different CCTV project has different feature and particularity,so when build a CCTV system,we need consider many factors.One of the most important thing in building cctv system is choose suitable transmission way.At present,coaxial cable,twisted-pair and optical fiber are three mainly transmission ways for CCTV system.
How to choose the transmission way and how long the three transmission ways can transfer?
Read this article you will find the answer.:-)
1-Coaxial cable
Transmission distance within 500m,only can transfer video signal,fit for no interference or weak interference environment.
2-Twisted-pair,also named network cable,usually use cat6 or cat5 in CCTV system.
When transmission distance between 400m~1500m,use Twisted-pair can show it's good performance and price advantage.
Twisted-pair features in CCTV system:
*longer transmission distance,higher transmission quality
*Convenient wiring,high-usage for cables.
Since there are 4 Twisted-pairs in one cable,except transfer video,the left pairs also can use for transfer audio,power and control signal etc.
*Strong anti-interference ability
*Cheaper price,easy to buy from every market
3-Optical fiber
Fit for the project which need tranfer 2km to dozens of kilometers.
Optical fiber features in CCTV system:
*Longest transmission distance,best transmission quality
*The strongest anti-interference ability
*Need professtional staff to do the wiring
*Expensive price
