How many type of home alarm systems? How to choose?
According to the signal transmission method between the detector and the alarm host, it is divided into wired and wireless. Wireless products are currently the mainstream and the first choice for home users.
The components of the wired anti-theft alarm system are transmitted through telephone lines or network cables. Its defense distance is limited and the installation is troublesome. The lines should be laid in advance during the construction of the house. The degree of intelligence is also low and is gradually being eliminated.
The wireless anti-theft alarm system uses wireless signal transmission between the various devices. It is suitable for places with more and more scattered monitoring points. It is ready to use and does not require advance wiring. Users can match the host and various detectors by themselves, which generally does not destroy the original decoration style.
What are the parts of the home anti-theft alarm system? How should I choose?
The home anti-theft alarm system can be divided into two parts: the alarm host and the front-end detector.
The alarm host is the most core part, usually installed indoors. Its main function is to control other external detectors, receive and judge the induction signals of external detectors, and convey the alarm signal to the owner or alarm according to the pre-set alarm method.
The front-end detector mainly performs monitoring and sends the received signal to the alarm host for processing. Its technical content is not high, and the difference between brands is not big. In theory, it can be mixed, but the dealer should be consulted when purchasing.
Generally speaking, “host + door magnet + infrared detector + remote control” can form a basic anti-theft alarm system, and detectors can also be added according to actual needs.
What is a defense zone? Are more defense zones better?
A defense zone is the smallest unit that can be identified by the anti-theft system alone. Each defense zone must be set as a defense zone type to respond specifically to the detector.
In theory, the more defense zones, the fewer dead angles and the higher the reliability. However, the more detectors need to be configured, and the cost will increase accordingly. Users should configure according to the monitoring area.
Where should the anti-theft alarm system be installed?
The location where the anti-theft alarm system is installed affects its use effect.
The host should be installed in the center of all detectors as much as possible to facilitate signal reception. Since the burglar alarm itself emits electromagnetic waves and is easily interfered by strong magnetic fields, it should be installed at a certain distance from large appliances such as TVs, refrigerators, and air conditioners. The front-end detectors do not have high requirements and can be installed as needed.
