Alarm host trend: monitoring alarm integration into prominence (1)

Alarm master as alarm system's "head" and "heart", its special identity allows alarm host development have been cautious.

Over the past ten years, "be careful driving have ten thousand boats" alarm host only is in its functionality and the transmission mode, make changes, from the single send alarm signal to have SMS/voice, listening/speaking, remote control, alarm linkage, and other functions from the telephone line to the GSM mobile network, broadband networks, and other means of transmission. However, even if the function more abundant, more diverse kuaijiehua transmission mode, but is always a high false alarm rate alarm system failed to solve a big problem. According to Nanjing British ante technology industrial co., Ltd. General Manager Liu patriotic in the past all of the alarm message, at least 90 per cent of the alert is a false positive, many false positives exhibition spend most of their human, material and financial resources. In this interview, most manufacturers have indicated, and monitoring system for consolidation is alarm host development trend, with video monitoring system in order to verify the validation function, alarm field to determine the reliability of alarm information is true, thus reducing false positives.

In fact, alarm and monitoring of linkage integration very early on has been tried and is still used, but this kind of alarm and monitoring of the integration is a low-level integration, two system completely to two separate subsystems, independent cable laying signal, the signal through the alarm to trigger output signal to the monitor system linked to start, it will alarm image signal transmission to the monitoring center to display and record, and may further linkage lighting system etc.

This type of alarm and monitoring integrated linkage applies only to a small extent, as the building or in the same community. But then as the alarm signal and image signal same cable transmission technology matures, such as network transmission technology and development, makes the alarm linkage of alarm video integration review technology and is keen to pursue. For example, according to the Tyco security device s DSC alarm products China area sales manager at Yuan Hong, 5, 6 years ago, TYCO has launched a video alarm review integration product, but the price relatively traditional alarm host much more expensive, and because at the time of the alarm host still rely on telephone alarm upload speed is slow, causing the video transfer is not smooth; in addition, the video bandwidth, you can only send a black and white pictures, the fragment is not up to real-time monitoring results. Perhaps deeper causes, that is not yet complete and perfect maturation of alarm and image management platform (a taste of the alarm system, whether domestic or foreign brands, has complete, perfect, complete alarm management platform), alarm monitoring and review of the machine in a short time after the market launch, the end result of effects of unsatisfactory and disappeared. Since then, the alarm host then did not dare to easily integrate with monitoring system.

In recent years, the alert monitor in one voice, abroad such products has been in full swing, and gradually spread to the domestic market.

While some manufacturers still unmoved, continue to delve into a traditional alarm host function then updates; but there is also a manufacturer of homeopathy, has launched a video alarm management software, and other monitoring alarm integration programmes.

Video + alarm, big collection of integration programmes

For monitoring and alerting for consolidation, many manufacturers have their own understanding.

Shenzhen Huaji e do more than just General Manager, said that the principle of the integration of video alarm is through existing monitoring system images, real time verification of alarm conditions of authenticity. Its realization approach there are three main ways: first, the alarm and monitoring is still as two separate systems, triggered by alarm signal monitoring system, but with the help of network traffic to a central management system integration in a manner similar to the earlier system. Just a transmission medium, early style is a phone line, now is the network; the second is a front-end detector Plus camera implementation review; third, alarm and video servers, back-end monitoring platform and unified management. After the second way is using the network. While Nanjing Ying Liu, patriotic, ante, at present the video alarm all-in-one of the core is video DVR plus alarm host, it will be transmitted over the network DVR and alarm host connected to the back-end management platform and unified management, when the alarm signal from the back-end management center can instantly view the alert live video video, real-time understanding of facts.

In order to allow everyone to have a clearer understanding of author interviews to content will monitor alarm integration programmes are generally grouped into the following categories.

Alarm master plus video server class systems

Although in foreign markets, alarm monitoring machine has a bunch of fried, but the domestic market remains a traditional alarm host occupies half of the country.

Most manufacturers on monitoring and alarming integration programmes still take a wait-and-see, only to focus on the wireless network's IP network alarm host development, real monitoring alarm integration products, while the Shenzhen Security co., Ltd. developed by EAVS system be considered domestic manufacturers of "precedent."

Shenzhen Security co., Ltd. technical engineer wearing more than a dream, "the full name Explorer-AlarmVideoServer EAVS", i.e. digital network alarm video servers, video surveillance and alarm systems integration.

It is the combination of alarm technology and H.264 video compression technology developed by alarm video surveillance system, the deployment status, current side object fires occur Aviso, video recorder will automatically turn on before and after the events of 60 seconds for the video, then the warning and video instant upload to the Network Center; at the same time client came in alarm signal automatically obtain monitoring video, alarm management centre operators or Security Service Center for immediate viewing is a false positive, true if the identified Aviso, by phone or SMS form to inform to the user.

In addition to video verification function, this system also has motion detection feature, the normal time monitoring on the spot.

When you move objects, invasion, the system will automatically alarm and video upload to the back-end equipment, thereby effectively reducing the video files on the storage device space occupied at the same time achieve video alarm function. At present, the product has been applied to the factory, shopping malls, retail management, communities, smart buildings and other places.

There are three main EAVS system

Features: first of all, easy to operate. Its own operating system, available via joystick keyboard, mouse, remote control, and other means for local action, can also be IE way offsite remote operation and settings. Secondly, the powerful. Back-end strong database management platform, integrated diversified transport, available through PSTN, GSM, TIP/IP, 3G, transmission, effectively solve the video transmission bandwidth, guaranteed transmission fluid and alarm of timeliness; again, highly integrated, economical and practical. Set alarm, video server and IE browse together, one device to meet a wide variety of security needs, effectively reducing the cost of the device user.

Detector Plus camera system

Detector plus video camera system, it is mainly composed of front-end with camera alarm detector and video alarm controller in the Terminal with monitoring and management software for your computer or information terminal.

When a suspicious object is detected, the system will alarm signal and image transmission to the monitoring center, or other information terminal devices, real-time scene image review timely interaction of external devices. If an earlier huaji launched such detectors, at the same time it also combines intelligent video analytics, automatically ignores environmental factors, probe protection area moving objects can be any set Shield region environment, automatically ignores Shield region objects move, when the object is exposed to or passing through, triggering the alarm and video trace trigger objects, greatly reduced due to environmental factors causing a false positive.
