Intelligent anti-theft alarm embarks on the era of integrated circuits

With the continuous development of the security industry, China's anti-theft alarm products with long-term stability have shown signs of change, and they are accumulating momentum. Although traditional anti-theft alarm products still occupy the mainstream of the market, the emerging new products and new technologies will eventually get rid of the shackles of the old technology, and they want to have a “star of fire, it will surely start the original” trend, perhaps in 2011, anti-theft alarm system The history of technology will record a new page.

The overall situation of alarm monitoring and integration has set new detectors and network alarm controllers. In addition to the emergence of a powerful multi-network alarm host, another development trend of the alarm system is the integration of alarm and monitoring. I believe this is also a consensus in the industry. At present, most of the domestic integrations are integrated with front-end alarm systems and monitoring systems that exist independently at the back end in a hardware low-level manner. This is also the most traditional integration method in the past; however, there are also some manufacturers that have truly integrated the two systems. Integration, such as the digital network alarm video server launched by Meitech and the network alarm video linkage server launched by Quanzhou.

Network alarm video server can be said to be an example of organic integration of video surveillance and alarm systems. It is combined with alarm technology and H. 264 An alarm video surveillance system developed by video compression technology. In the armed state, when there is an object triggering the alarm at the current end, the video recording will be automatically started, and the video will be recorded 60 seconds before and after the alarm, and then the alarm and video will be recorded. Instantly upload to the network center; at the same time, the client can automatically retrieve the surveillance video when the alarm signal arrives. The alarm management center operator or the security service center can instantly check whether it is a false alarm. If the police intelligence is true, then the phone voice Or inform the user by SMS.

In addition to the video verification function, this type of system also has a video motion detection function. In the armed state, the system monitors the scene in real time. When there is a mobile object intrusion, the system will automatically alarm and upload the video recording to the back-end center. Effectively reduce the occupancy of video files to the storage device space, and at the same time achieve the video alarm function. The system integrates anti-theft alarm, video server and IE browsing. One device can meet a variety of security requirements, effectively reducing the user's expenditure on equipment costs. The system has been widely used in factories, shopping malls, chain operations, communities, smart buildings and other places.

Perimeter Precaution: Installation Prevention Smarter Perimeter prevention systems are generally deployed in the perimeter boundary wall or in the outer wall of the interior building, often as the first link in the security system. When an object crosses an intrusion, it can threaten the intruder and at the same time, it can promptly notify the security personnel to rush to the place where the crime occurred. For a long time, the perimeter alarm detection has adopted more mature active infrared radiation technology. However, due to the fact that the technology is vulnerable to environmental factors, the technology, despite its satisfactory price, often has flaws in its leak/false positives. Headache; The pulsed cable perimeter alarm system that emerged, undoubtedly, the pulse cable system at a significant increase in price at the same time, the alarm performance has also been greatly improved, the false alarm rate of leakage is also significantly lower than the active infrared, but corresponding The difficulty of construction and the amount of works are also greatly increased. Storms, rain, trees, etc. will also interfere with the construction. The amount of construction and maintenance work is very large.

Of course, there are other technologies in recent years, such as sensing cable technology, which has a serious lack of active prevention and deterrence.

Now, we have introduced the fiber perimeter protection system, which is an alarm platform based on fiber-optic sensing technology capable of sensing weak vibration signals. The sensing fiber can be arbitrarily installed on the fence, underground or wall, and the intruder is trying to climb. Vibration will change the mode of light transmission, after analysis and processing by the signal processing unit, thus giving an alarm signal for intrusion.

The perimeter alarm technology adopts ordinary optical fiber cables as distributed sensors. The advantages are obvious: there is no electromagnetic radiation interference, and it is not affected by the electromagnetic, weather, and geographical environment of the environment. It has strong anti-interference ability and is not affected by EMI and lightning strikes. Outdoor components are passive devices. For example, at the 2010 Expo, Beifang Guo'an and Ningbo Norco launched a fiber-optic signal perimeter protection system that has made new technological breakthroughs.

·Intelligent learning function. The biggest problem of the perimeter protection system is that it is vulnerable to the outdoor environment, and it is prone to false alarms and omissions, especially when storms occur, or the vibrations of passing vehicles, aircraft takeoffs and landings, etc. often lead to accidental missed timing. The perimeter protection systems launched by Beiyou Guo'an and Ningbo's Nocco have developed intelligent learning functions. They learn and memorize environmental conditions through “self-learning” techniques. When they are officially running, similar environmental conditions can be blocked. For example, false alarms, such as wind, rain, and small animal activity, can be automatically “deleted”, allowing the detection of true intruder signals to be optimized; a fiber optic cable goes to the end technology. As we all know, in the past, the fiber perimeter protection system used a single zone to deploy a cable. The biggest drawback of this kind of system is that the amount of fiber engineering is large, and Ningbo Nocco's fiber signal feedback system realizes that only one fiber is laid from the perimeter to the perimeter, and when an intrusion occurs at a certain position along the fiber laying The back-end control platform can accurately detect the location of the intrusion point. This system not only saves the amount of fiber cabling, but also saves the manpower and material cost of troubleshooting the exact location of the intrusion.

Summary: Integration is a major trend in the alarm equipment manufacturers in addition to the burglar alarm system front-end products (detectors and control host) technology has a lot of breakthroughs, in the back-end management platform software operations, also have a larger The improvement has seen the management platform with a very strong function. In the past, users used more foreign alarm platform products, resulting in the operating interface is mostly displayed in English. It is worth noting that, at the 2010 Expo, the author was pleased to discover that there was a full Chinese software interface. For domestic users, the operation will be even more Simple and user-friendly.

On the other hand, as far as the aforementioned integration is concerned, the low-level linkage on the alarm monitoring access control hardware is not new. The next major development is the integration of the alarm monitoring access control from the software's integrated management platform. For example, TYCO recently launched Integrated management platform system, which can integrate the software of the alarm monitoring and access control tripartite on the back-end management platform through the protocol, ensuring that when the alarm occurs, it can start the interaction with the TV monitoring and access control system for the first time, and can actually realize Monitoring, real-time control of access control.

We have already embarked on the 2011 journey. We believe that China's anti-theft alarm industry has a “star fire” in 2010 and will surely realize the “Liaoyuan” trend in 2011. Let us wait and see.
