The integrated intrusion detector performance testing system is mainly used to simulate the performance of active infrared, passive infrared, infrared and microwave composite detectors. The device has the advantages of complete function, simple operation, stable performance, high control precision, accurate collection and good security. In addition, the wireless transmission technology is adopted, and the remote operation can be carried out. The main goal of this paper is to develop the intrusion detector detection system according to the standard technical requirements and test methods, to meet the needs of product detection, and finally to improve the competitiveness of domestic related enterprises in the international market. The device can test whether the intrusion detector has the problem of false alarm and false alarm, test the anti-interference ability and the performance parameters of the intrusion detector, and then improve the product quality of the intrusion detector. It is very helpful to develop new products.
