Alarm Monitoring Alarm Host Integration gradually emerging big market – security
Alarm System Alarm host, as the "head" and "heart" of their special status makes the development has been carefully master alarm. Years, "Care and diligence bring luck," the alarm host is only in its functions and transmission modes to change from single to send alarm signals to have the SMS / voice, Monitor / Intercom, remote control alarm linkage functions, from phone lines for transmission to the GSM mobile network, broadband Internet and other means of transmission. However, even if functional richness, efficient transmission of increasingly diverse, high false positive alarm system has always failed to solve a difficult problem. Andersson, according to the British Technology Industrial Co., Nanjing Company Liu Aiguo, general manager, said in the past all the alarm information sent, at least 90% pure false alarm, many of the false positives out of the police spend a lot of manpower, material and financial resources. In the interview, the majority of manufacturers have indicated, and Monitoring System Integration is the development trend of alarm host, with a video monitoring system to verify the validation status of alarm site to determine the authenticity of alarm information, thereby reducing the false alarm rate.
In fact, alarm and monitoring of linkage integration has been tried long ago, are still using, just kind of alarm and monitoring of integration is the low-level integration, the two systems completely to form two independent subsystems, independent laying signal cable, through the alarm signal to trigger the output signal to the monitoring system linked to the start point of the alarm signal transmission to the monitoring center of the image displayed and recorded, and can be further linked lighting systems. Integrated alarm and monitoring of such linkage is only applicable to small areas inside the building or the same as a district of. But then as the alarm signal and image signal with the cable transmission Technology Maturity, such as network transmission technology and the development of the proposal made by the alarm monitor alarm triggered video linkage integration of people eager to review the technologies have been pursued. For example, security equipment, according to Tyco's DSC Alarm Product Yuan Hong description sales manager in China, in 5,6 years ago, TYCO, once introduced integrated video alarm review products, but the price is much more expensive than the traditional alarm host, and by that time the alarm system still relies on the telephone line for alarm mass, resulting in slow video transmission is not smooth; In addition, a large video bandwidth and can only send black and white clips pictures reach real-time monitoring results. Perhaps there are deeper reasons, that is not a complete alarm sound mature and image management platform (a taste of the alarm system, whether domestic or foreign Brand Have full, complete, mature alarm management platform), the alarm monitoring machine in short review Market After running, finally disappeared due to poor effect. Since then, the alarm host and then am not easily integrated with control systems integration.
Recent years, alarm monitoring renewed calls for one machine, the development of such products abroad have been in full swing, and gradually spread to the domestic market. Although some manufacturers still unmoved, continues to delve into the functions of a traditional alarm and then update the host; but there are also manufacturers the flow, introduced a video alarm management software, integrated solutions and other kinds of monitoring and alarming.
Video + alarm, a large collection of integrated programs
For monitoring and alarm integration, many manufacturers have their own different interpretations. Executive General Manager of Shenzhen China International Electronic more than just that the principle of integrated video alarm monitoring system through the existing images, real-time verify the authenticity of alarm conditions. There are many ways There are three ways: First, alarm and monitoring remain two independent systems, triggered by alarm signal monitoring system, but the use of network transmission to the central management system to achieve integration in a manner similar to the earlier system. Only transmission medium, the differences in early way of telephone lines, it is the network; Second, front-end detector plus camera to achieve review; third alarm host and video servers, unified management by the back-end monitoring platform. After two kinds of methods are based on the network transmission. The British Ante Advancement in Nanjing is that one is talking about the video alarm is the core of the video machine plus DVR alarm host, it will be transferred over a network host to connect to the DVR and alarm management platform for unified management of the back end, when there are warning signals came, the back-end management center can immediately see alarm live video recording, real-time understanding of reality.
