Basic concepts of wired intrusion detection alarm system
Wired intrusion detection alarm system refers to the wired transmission mode between the intrusion detector and the alarm controller. At the same time, the alarm controller and the upper alarm center also adopt the wired transmission method.
In this system, the intruder detector is installed separately from the alarm controller. The intruder detector is installed on the guard site, and the alarm controller is placed in a duty room, a control center or a security department at a certain distance therefrom, and the alarm controller is connected through an appropriate transmission line. There are many kinds of transmission lines, such as twisted pair, telephone cable, coaxial cable, optical cable and so on. The above-mentioned transmission line is also used to exchange information between the alarm controller at the user end and the alarm center at the upper level.
