The perimeter intrusion alarm system serves as a critical component of the airport's air defense security framework. Based on technical classification, these systems can be classified into contact and non-contact types. This paper examines the working principles and characteristics of commonly utilized contact perimeter intrusion alarm detection technologies in airports from a security prevention perspective. It analyzes their practical application effectiveness within airport settings and offers recommendations for minimizing false alarms. Additionally, this study introduces exploratory solutions from the industry aimed at reducing false alarms, thereby providing valuable references for the implementation of widely used contact perimeter intrusion alarm detection technologies in airports.
