blocker Jamming Alarm System
The traditional local area network communication of the security alarm host system adopts 433MHZ ASK wireless communication, which has the advantages of low cost, easy development and long transmission distance. But there are also some fatal shortcomings, such as poor anti-interference ability, low data transmission efficiency, and easy string code. The population is sparse, and every household lives in a large villa, and the distance is far apart, so there are relatively few sensors within a certain range. signal jammer uses ASK wireless communication, which is not a big problem.
At the same time, several sensors alarm at the same time. Because of the mutual interference and collision of ASK wireless data, the alarm host cannot obtain the alarm information, which leads to the abnormality of the security alarm system.
