In the wireless intrusion detection and alarm system, although the intrusion detector and the alarm controller are also placed on the guard scene and the duty center respectively, the difference from the wired intrusion detection and alarm system is that there is no need to apply high transmission lines between them. The wireless signals are used to connect electrical signals, that is, to transmit electrical signals by means of space electromagnetic waves. If the duty center needs to send an alarm signal bomb to the upper level alarm center, this similar transmission method can also be used. Basic composition of wireless intrusion detection alarm system.
The intrusion detector and the wireless alarm transmitter make up a wireless alarm detector. These two components can be separated independently. When they are used, they can be connected by wire (limited to 10 meters), or they can be assembled. Together, it becomes a two-in-one component.
In general, a wireless alarm receiver can form a wireless alarm system with a certain number (a few to several thousand) of wireless alarm transmitters.
The wireless alarm system is particularly suitable for use in places where there are many monitoring points, and where the prevention of the issuance of the site is more dispersed, more distant or inconveniently set up the transmission line. Moreover, because the radio transmission telecommunication is farther away and can reach a distance less than that of wired transmission, long-distance alert and alarm can be performed, and a large area of ​​wireless networking can be formed within a range of several kilometers to several tens of kilometers. alarm system.
Wireless alarm detectors can be arbitrarily changed according to the needs of the user to prevent areas, and even can be placed on a moving object such as cars, installation and use of flexible control range. Using wireless frequency division, coding and other technologies, a wireless alarm receiver should be able to control dozens or even hundreds of thousands of wireless alarm detectors. If a wireless alarm transmitter at the monitoring site is simultaneously connected with detectors having different protection functions (such as anti-theft, anti-intrusion, burglary, fire prevention, explosion-proof, etc.), a multi-functional integrated wireless network within a region can be formed. alarm system. Such a system can be widely used in industrial and mining, enterprises and institutions, office buildings, shops, banks, warehouses, museums, and urban residential areas and villas.
