Thus, video alarm analysis technology has changed the traditional passive acceptance of video surveillance experience model, change from passive to active to monitor the live video recording of the real-time analysis. It on the video image of the target automatic monitoring, identification, tracking and analysis, and computer programs automatically filter through to filter out a large number of users do not care about video surveillance video.īy analyzing and understanding the contents of the video screen to provide users with useful for monitoring and alarm key information. Video alarm system is digital, network-based video surveillance, monitoring based on computer vision technology to the scene of the video image content analysis to extract key information in the scene, and the formation of the corresponding event and alarm monitoring mode, a new generation of video-based content analysis of the monitoring alarm system. According to infrared imaging system in the central part of – detectors work in different ways, thermal imager can be divided into cooling type infrared imaging system and non-cooling type infrared imager. Focal plane detector for sensing the temperature distribution of the object, and converted to a weak electrical signal follow-up circuit to a weak electric signal amplification and logic processing electronics, which can clearly capture objects to the target temperature distribution image processing software is on the amplified output signal processing, showing the temperature distribution for the target object visible light image. Uncooled infrared imaging system is a hardware system used to detect the target object’s infrared radiation, and by photoelectric conversion, signal processing means, the temperature distribution of the target object image is converted into a video image of the high-tech products, its core components and technologies for the FPA detector, the follow-up circuit, image processing software such as three parts. Not only to make up for the deficiencies of existing video surveillance systems, and improved security systems automatically identify and alert other related automation! System at night or adverse weather conditions (such as rain, fog, etc.) work, not only can save a lot of manpower, while the day when the weather allows real-time alarm. In this case, the advance, the thermal imager, and video alarm system on there! This system is based uncooled infrared imaging system or hardware such as visible light camera systems, infrared / visible composite image, video, image processing and automatic alarm behavior analysis software with integration to existing video surveillance system to monitor labor under good weather, after the evidence but also to enhance all-weather conditions for the care-free man-made, computer automatic real-time alarm function. With the development of science and technology, before the kind of man with visible light cameras and surveillance video combination for the daily security of the Master is no longer used! Particularly at night and adverse weather conditions prevent lack of capacity is more!
