I want to install a set of monitoring, a total of 15 cameras, the farthest camera from the hard disk recorder 500 meters, how to install? What equipment?
The general home about three hundred of the camera can need a power cord (then 220V mains), a 12V power supply, a video cable (connected capture card) video line with 75-3 line on the line, the line needs to use two BNC head to connect the camera and capture card software, the collection cassette with a CD-ROM, a collection card driver and monitoring system, the installation is relatively simple
Shenzhen Xin Sheng security that if the use of active video transmitter, you can spread to 500 meters, the premise is better than the wire, but doing so down the cost of fiber is not much cheaper.
Need to install the video capture card and monitor the number of camera cameras to determine the number of acquisition cards (a collection card with four cameras), if the future will increase the camera, you can directly use 8-way card card collection of about 300 yuan, about 200 camera To a few thousand range
