Distributed Video Surveillance Alarm Linkage System Research

With video monitoring technology has been applied fully on many occasions nowdays. The technology has been developed in the areas of intelligence, integrated and network field at present, especially, intelligence has been valued in the area of video monitoring and has become an important aspect in the development. Video monitoring system has many applications in many areas, but they are running in this way, staff on duty and the video store, in most cases, that is, monitoring staff which is on duty observes many cameras at the same time while system stores the captured video or do some special work to the captured video pictures to suit the needs of monitoring daily work and some special requirements.However, the face of long-term duty stationary video surveillance easily lead to fatigue and let your guard down, which occurred in potential safety problems, although you can later view the video, it's too late for some problems which need to deal with promptly.Distributed video monitoring alarm system has been used mainly for improving the monitoring system's shortcomings and deficiencies. The system used image matching techniques to extract images from the captured video by the camera according to the set intervals of the time, and compared the two adjacent images. If the similarity within the set range, suggesting no significant change in the video, and when the similarity between two images exceeded the set range, the system would do whistle alarm promptly to attract the attention of the staff on duty, and the system would tell clearly the source of the alarm at the same time.Distributed monitoring video linkage alarm system has applied very well. Since the system was contributed to found safty problems promptly. The system is not only fully enhanced the role of video monitor, but also largely reduced the intensity of monitoring staff on duty who could concentrate on the handling of the security risks in time.
