Anti-intrusion IoT technology redefines perimeter security

As people's awareness of perimeter defense gradually increases, more and more companies or enterprises will install perimeter defense products in important areas and important equipment. From traditional infrared beams, video, electronic fences to integrated IoT solutions, so far, there has not been a day-of-week detection technology on the market that can meet any environmental application. A single form of sensing and simple trigger discrimination cannot meet the growing needs of users, and the integration of perimeter security products with other security systems (access control, monitoring, etc.) or business systems is becoming more and more important. However, for users of perimeter security products, the concept of "a substitute for a wall" is still deeply ingrained. Many users think that perimeter security products are just a substitute without spending too much money on them, and they are invisible to the product. Added value is not understood. Perimeter security technology evolution Roughly speaking, the development process of perimeter security technology can be roughly divided into three stages. The first generation of perimeter security system: mainly based on video surveillance, real-time video playback through the video screen to monitor the perimeter, the main equipment is an imitation/digital surveillance system, the system defects are relatively obvious, for example, it can only collect evidence after the fact, and personnel Monitoring is prone to visual fatigue, and currently it can only be used as one of the auxiliary wrists. The second-generation perimeter security system: Compared with the first-generation perimeter security system, it can report to the monitoring personnel in time. The products currently used are vibrating optical fibers and tension fences, but the probability of false alarms and missed alarms is high, and there is no independent intellectual property rights. The third-generation perimeter security system: The third-generation perimeter security system is supported by the Internet of Things technology. The principle of the system is multi-sensor collaborative sensing. After similar "spider web" planning, sensors are linked to each other, but this emerging technology costs Relatively high and system wide. Next-Generation Anti-Intrusion Technology - IoT Perimeter The anti-intrusion technology of the Internet of Things can accurately detect what the purpose is, what the center is, and what to do. Change the post-event follow-up investigation to event warning, and change the traditional security mode. A new generation of anti-intrusion system that uses the Internet of Things technology to realize collaborative perception, adopts a "target-driven" front-end detection system to complete the detection, positioning, classification and identification, trajectory tracking and other functions of the intrusion target, and can pass the front-end detection equipment (such as Laser beaming) and acousto-optical linkage mechanism, release alarm information for behaviors such as climbing over, low-altitude parabolic, fence damage, etc., accurately and timely report abnormal intrusion events, record alarm time, location, image and other information, and support detailed inquiry and printing , complete all-weather, all-day active protection. The main features of IoT anti-intrusion technology are: Multi-arm collaborative sensing, no missed alarms and low false alarms; Self-adaptive mechanism suppresses environmental disturbances; Real-time monitoring of equipment status, remote maintenance and fault self-checking; Load balancing completes trouble-free operation; Customized development is highly coupled with user business. 1. Multi-sensing wrist co-processing In IoT security sensing, there are not only video sensing nodes, but also sound sensing nodes and vibration sensing nodes. By generating relevant signal waveforms through them, it not only has the ability of environmental self-learning, but also can adjust the feature information extraction and analysis algorithms through the dynamics of different target sizes, types and behaviors, so as to complete the specific analysis and linkage driven by the purpose. (1) Front end (before the control box) Stop "automatic review" and use chain node detection as the front-end watch. When it detects an abnormality, it will trigger the start of auxiliary detection devices such as intelligent video, and complete the comprehensive decision-making of various sensing devices at the front end; combined climate information as a Threshold segmented adaptive conditioning input to suppress the impact of bad weather. (2) Back end (command center) The result will be more reliable detection results. If necessary, after manual review, it will enter the final alarm classification processing process. 2. Compatibility and separation with other devices For some key areas and gateways, some highly targeted auxiliary detection means can be used, such as laser beam shooting, infrared curtains, Weibo radar or lidar and other equipment. IoT technology guides intrusion prevention At present, the perimeter security system based on the Internet of Things technology has been out of the laboratory, and has been recognized by users in many application areas related to public safety, especially the application in airports, prisons and other places is particularly eye-catching. The IoT perimeter system, with its huge influence on technology and market, will surely lead intrusion prevention into a new era
