Small to fences, watchdogs, to the city walls, moats, people's attention to perimeter security has never stopped since ancient times. Today in the 21st century, perimeter security products are also undergoing an iterative transition from traditional to modern. From the beginning of infrared radiation, video, electronic fences to IoT integrated solutions, there are so many new perimeter security products, but there is still no detection technology to meet the application of any environment. Increasing user demand is not being met, and the ability to enhance the integration and integration of perimeter security products with other security systems (access control, monitoring, etc.) is becoming imminent. Mine the second generation of perimeter security system is a system now more commonly used. Relative to the first generation perimeter security system, it can be reported to the monitoring personnel in time. The system principle is based on the signal interpretation algorithm. The products currently used are vibrating fiber optics and tension fences, but the probability of false alarms and missed alarms is high, and there is no independent intellectual property rights. The latest third-generation perimeter security system is supported by the Internet of Things technology. The system principle is multi-sensor collaborative sensing, which is linked by sensors similar to the "spider web" layout. It can be said to be more precise and has a wider coverage. A new generation of intrusion prevention technology - IoT perimeter IoT anti-intrusion technology can accurately detect what the target is, what place, and what to do. Change the after-the-fact tracking investigation to an early warning and change the traditional security radar. A new generation of anti-intrusion system that uses IoT technology for collaborative sensing adopts a "target-driven" front-end detection system to realize functions such as detection, location, classification and recognition, and trajectory tracking of intrusion targets. The shortcoming of this emerging technology is that the cost is relatively high and the system scale is large. The main features of the security radar IoT anti-intrusion technology are: The perimeter security system has multiple means of collaborative sensing, no leakage, low false alarm, and adaptive mechanism to suppress environmental interference. At the same time, the device status will be monitored in real time, remote maintenance and fault self-test, as well as customized development and user services. Perimeter security system multi-sensing means collaborative processing In the IoT security sensing, there are not only video sensor nodes, but also sound sensing nodes and vibration sensing nodes. Through the generation of relevant signal waveforms, the radar not only has the environmental self-learning ability, but also can adjust the feature information extraction and analysis algorithms by setting different target size, type and behavior dynamics to achieve specific analysis and linkage under the target drive. The front end of the security radar (before the control box) will also perform "automatic review". The chain node detection is used as the front-end guarding means. When it detects an abnormality, it will start auxiliary detection means such as intelligent video, and complete various sensing means at the front end. Comprehensive decision making. At the same time, there is no need to worry about the problem that this kind of radar can't work under bad weather. It combines meteorological information as a threshold segment adaptive adjustment input to suppress the impact of bad weather. Conclusion: The attention of perimeter prevention has never declined, but with the advancement of science and technology, everyone is not only satisfied with the simple physical nursing home, the development of anti-invasive Internet of Things technology makes the perimeter security radar more intelligent and accurate. No leaks, low false alarms, so that everyone lives in a safer environment.
