It can be divided into three parts from the function: the detection part, the on-site processing part, and the subsequent processing part. The types of defense probes mainly include door magnets, passive infrared detectors, active infrared detectors, emergency buttons, smoke/fire detectors, flammable gas probes, etc. These components form the detector part of the alarm, and have live audio alarms and The alarm host and the telephone line and the dedicated data line that automatically dial the preset telephone voice alarm function constitute the on-site processing part and the subsequent processing part. 2/6 Product selection--From the perspective of alarm installation, the product can be divided into two types: wired and wireless. The wired method has the advantages of reliable communication, strong anti-interference ability and low device cost. It is suitable for new construction. A building where cables can be reserved in the wall. The main disadvantages are poor maneuverability and inconvenience to adapt to the changing requirements of users and products. It is very difficult to install and construct in a renovated room. The wireless method can avoid the connection between the probe and the host to destroy the interior decoration, and has the advantages of flexibility and simplicity. The main disadvantages are the disadvantages of being susceptible to external electromagnetic waves and relatively high device cost. 3/6 From the function of the alarm, the product can be divided into two types: on-site alarm and smart phone alarm. The on-site alarm is when the thief happens, the probe transmits the detected signal to the host, and the host receives the signal. An audio alarm sounds on the spot to deter thieves. In addition to the function of on-site alarm, the smart phone alarm can also automatically dial the preset phone number of the user.
