The popularization and advancement of science and technology have made the original noble and mysterious anti-theft alarms enter ordinary families. How can I buy a set of practical and affordable home burglar alarms for my own family?
The basic composition of a home burglar alarm-a home burglar alarm usually consists of the alarm host, various types of defense probes, and user operating parts (keyboard, remote control, etc.). It can be divided into three parts functionally: the detection part, the on-site processing part, and the subsequent processing part. The types of defense probes mainly include door sensors, passive infrared detectors, active infrared detectors, emergency buttons, smoke/fire alarm probes, flammable gas probes, etc. These components constitute the detection part of the alarm, and have on-site audio alarms and The alarm host, telephone line, and dedicated data line that automatically dial the preset telephone voice alarm function constitute the on-site processing part and the subsequent processing part.
Product selection--From the perspective of alarm installation, the product can be divided into two forms: wired and wireless. The wired method has the advantages of reliable communication, strong anti-interference ability, and low component cost. It is suitable for new construction and can be installed on the wall. A building with a connection line reserved inside. The main disadvantages are poor mobility and inconvenience to adapt to the changing requirements of users and products. Installation and construction in a room that has been renovated is a very difficult task. The wireless method can prevent the connecting line between the probe and the host from damaging the interior decoration. It has the advantages of flexibility and simplicity. Its main disadvantages are the susceptibility to interference from external electromagnetic waves and the relatively high cost of components.
In terms of the function of the alarm, the product can be divided into two types: on-site alarm and smart phone alarm.
