How to use the network cable to connect the surveillance camera?
Short distance directly with the network cable can be, I remember as if 40 ~ 70 should be no problem (my longest used 20 to 30 meters). If you can buy twisted pair transmitter, then each pair of cameras need a pair of distance greater than 300 meters with active, active recommended front-end ground. If you use a network camera or a normal camera + digital module (this name is not allowed) direct crystal head + switch.
2, some camera is a digital camera, direct use of cable digital transmission of video, cameras and video recorders are connected through the network cable on the switch, are transmitted through the network video.
1, the use of two of the network cable transmission video. If the camera is a direct video output, usually with a dedicated video cable video, but also useful cable transmission video (only two of them), often in order to save costs.
Network cable to do monitoring line in two ways, but depends on the camera's video transmission.
