Analogue cameras | characteristics of analog cameras | the analog camera parameters analog camera features, ease-of-use analog cameras: closed, only in the internal monitoring can not remotely monitor practicality analog cameras: video information only local storage, nor remotely view, is not easily damaged by lawless elements. Integrated analog cameras: analog cameras to the DVR (Digital Video Recorder intended for digital video recorders, and only from the literal to understand, it does not specify that the recording medium is a tape or hard disk) connected to the number of channels of the DVR have a certain restrictions, the DVR then full, additional camera but also increase the cost of the hardware. Installed analog cameras: coaxial cable connected to each camera, and connected to the control platform, video equipment, display device. Each additional way to be re-wiring, and no off-the-shelf network. The remote analog cameras: only local watch image management. Scalable analog cameras: expansion work is very difficult, each analog cameras require a special cable will affect the image quality when using long cable. Cost analog cameras: coaxial cable is very expensive, used the RG59 750hms of standard coaxial cable than the high-quality network cable from 30% to 40% more expensive. Each analog cameras with cable, if you have a lot of cameras, you must purchase a lot of cables and spend money specifically for the installation and deployment of these cables. Human and higher maintenance costs, in addition to the cost of system construction will also include the cost of analog cameras, VCRs and tape.
