Resolve Ethernet alarm technology promotion and application (1)

First, the burglar alarm system of the market situation

Burglar alarm system and video surveillance systems, access control system, building intercom system and electronic patrol systems together form the security and protection system, is essential for security means.

Burglar alarm system is used in protection monitoring area with microwave, infrared technology, auto-detect intrusions and generate alarm signals, information will be sent to the police control center management host, issue the sound and light alarm linkage and Aviso location information, auxiliary prompt security personnel start emergency measures plan. Although after years of development, security alarm products have been marches, users are concerned about the product is reliable and functional diversity. But in the domestic market, interconnection of alarm and integrated demand is also increasing. Burglar alarm systems networking mode is generally include city, County and public security systems-networking/police station-centric networking/residential networking/networking, networking units including telephone line, private bus, networks, wireless networks, telephone lines and bus system is the most widely used. Phoneline Networking-type security alarm systems used in commercial, financial, schools, government agencies, and other important places, alarm host after receiving presents, in addition to the local interaction through telephone lines to automatically dial-up or manual operation mode to the higher straight pipe sector or security service of alarm centre forward information, answer alarm the Centre is responsible for handling events and exhibition services. Private bus alarm system used in factories and enterprises, residential area, in addition to local linkage, the alarm information is generally only transfer to the unit's control room. How to ensure a rapid response to intrusion detection, minimize system of false positives? this has always been a burglar alarm companies pursued goals. In addition to applying all kinds of advanced opto-biotechnology and intelligent filtering analysis algorithms to improve alarm detector of index, you can also integrate with a video surveillance system by means of image review, determine police pass quickly and accurately.

Second, the burglar alarm system trends

Regional networking of

As the security awareness, and intelligent building vigorous development, anti-theft alarm system, the average point capacity also increased rapidly, alarm detectors from several, a dozen to hundreds and hundreds.

Prevention area expansion, construction of wiring of complex, the location of the detector distribution adjustment and expansion, have on the security alarm system control management and system design schema new requirements. Burglar alarm system communication link generally include alarm detector and alarm controller networking between, as well as alarm controller and the control centre of networking. In the actual construction of the deployment process, in order to be flexible with probes and cabling, detector and alarm controller are still using the traditional switch quantity signal transmission, alarm control and the control centre of networking is the system is stable and robust flexible extended key. Phone line networking mode operation costs, networking is slow, in order to address more than one user at the police wiring plug, alarm response center requires configuration of multiple alarm controller and multi-channel communication link. Private bus interconnection operating costs low, network speed, but the coverage range is small, the track laying reliability, transmission susceptible to interference. Prevention area increase makes alarm system monitoring scope extension, located in every region of the alarm controller must have the perfect advanced communications network support, the control centre of the security staff before you probe system within the alert status at a glance, traditional networking mode changes the face of this class of unsustainable, and Ethernet alarm technology is making this request implementation possible.

Linkage integration

Multiple system multiplatform integrated security system development has become a major trend, alarm system is no exception.

Where, on alarm information and video review of strong market demand makes the burglar alarm system and video surveillance system integrates the linkage between the most necessary. If the monitoring area appear Aviso, security personnel might not normally appear on the scene quickly, if at the same time, many events emerged also captive to multiple places. If the alarm system can linkage video surveillance system, you can control center instant real-time observation of the alarm field, accurate identification review whether any intrusions or false positives, automatically record the alarm time, and location information, automated video capture and video recording and notification of relevant law enforcement authorities. Depend on the police with technology and peace as a result of urban construction, many first-line Center City has made the deployment of 20 000 or even 30 million camera concept and planning, communities and regions has initially "cover-to-surface, monitoring to control line, to the point" 24/7, multifunctional technology preventing network system. In-built image acquisition devices, government investment in construction accounted for only a very small percentage, mostly financial organization, school, shopping malls, hotels, businesses and residents of the community, within the social power to invest in the construction of the monitoring system, a large number of owners disposable camera control installation makes the video review of the difficulty to reduce significantly, and matrix/DVR/third-party integrated management software, and other control devices and platforms, intelligent linkage processing feature perfect also simplifies the complexity of integrated management. In addition, since the majority of small and medium-sized security alarm system owners have not yet accepted alarm services consumption concept, alarm centre's main services customers are concentrated in Bank/cultural/schools focus on prevention unit. Ordinary users can use their own management, alarm systems, such as instant alarm, delay alarm, 24-hour standoff, and other professional alarm host complex feature set is difficult to fully grasp, let alone the quick apply, and the binding of the video surveillance system, you can simplify system using difficult, let users through an intuitive and simple image observation and alarm detection combined with daily security work.
