Security monitoring project 755 transmission distance can reach 500 meters?
The key is: what about the scene? Is there any interference? If absolutely no interference, you can use 75-7 or 75-5 of good quality, but must not be in the middle of joints. During construction, make sure the cable is good and no broken skin is allowed. If there is interference, there will be too many modes of transmission.
128 series of 75-5 pure copper wire, in the absence of interference, the theory should be able to transmit 500 meters.But if it is so far, very few applicators will use video coaxial direct transmission, transmission will generally use fiber and voop way. Moreover, if the wiring environment has strong interference sources, such a distant signal, video effects will be affected.
Coaxial cable diameter of more than 0.9CM can reach 500 metersNow you are talking about 75-5 lines, what is the specific situation, if the 75-5128 national marking, no problem75-596, that's dangerous
