Monitoring Alarm Integration Gradually Emerges Alarm Market

Alarm system alarm as "mind" and "heart", his special status allows the development of alarm has been careful. Ten years, "careful drive perpetual ship" alarm is in its function and transmit only changed the way, by a single alarm signal is sent to SMS/voice, listening/speaking, features such as remote control alarm linkage, from the telephone line to the GSM mobile networks, broadband network and other transport modes.

However, even more feature-rich, transmission of more diverse, fast, high false positive rate has always been that the alarm system failed to resolve a problem. According to Nanjing said Liu Aiguo, British technology industry limited, alerts all information in the past, at least 90 per cent of the alert is false positive, many police spent a lot of false positives of human, material and financial resources.

In this interview, most manufacturers are indicated, integration with monitoring camera system is the inevitable trend of the alarm, with video surveillance camera system validation function to verify alarm conditions in order to determine the reliability of alarm information is true (spy surveillance equipment), thus reducing the rate of false positives. Actually, alarm and monitoring camera of linkage integrated is early has was attempts to had, now still has using, just the class alarm and monitoring camera of integrated is low-level integrated, two system full to two a independent of subsystem way, independent laying signal line cable, through alarm signal to triggered output linkage signal to monitoring camera system to started, will alarm point image signal transmission to monitoring Center for display and records, and the can further linkage lighting system.This type of alarm and monitor integrated linkage applies only to a small scale, as a floor, or within the same community. But later, as the alarm signal and image signal with the maturity of cable transmission technology, such as a network transmission technology and development, alarm monitoring and linkage alarm caused by the video integration review of technology and was keen to pursue. Such as, according to taikean anti-device its DSC alarm products China area sales manager Yuan Hongdao describes, in 5, and 6 years Qian, TYCO on had launched has video alarm review integration products, but price relative traditional alarm host expensive was more, and because then of alarm host remains by phone line alarm upload, speed more slow thus led video transmission not smooth; also, video occupied bandwidth large, only sent black and white fragment pictures, up not to real-time monitoring effect. Perhaps there is a deeper reason, is not a complete sound and mature alarm and image management platform (a taste of the alarm system (home surveillance equipment), whether domestic or foreign brands, has a complete, perfect, complete alarm management platform), so the alarm monitoring and review in a short time after the market finally disappeared due to poor effect.

Since then, the alarm and then dared not easily integrated with the monitoring and control system integration. In recent years, the cry of alarm monitoring machine again, this type of product development is in full swing in foreign countries, and gradually spread to the domestic market.Although some manufacturers still unmoved, continue to delve into the traditional alarm function then updates; but there are also homeopathic manufacturers, launched a video management software and other kinds of monitoring alarm integration solution.from:electronic surveillance equipment
