The security market is huge, including video surveillance, intrusion alarm, entrance and exit control, video intercom, access control, electronic patrol, vehicle anti-theft, network alarm and other sub-sectors. Video surveillance is a core part of the security industry. The most important physical foundation of the entire security system has therefore become one of the first areas of development in the security industry.
With the development of the times and the increasing requirements of users for security precautions, video surveillance has become more and more widely used in the security field. Video surveillance has become an ordinary demand.
Video surveillance is moving in the direction of big network, high definition and intelligence, especially the outbreak of high-definition and intelligent demand. The whole industry has entered the digital age.
With the maturity of video surveillance systems, the current video surveillance systems have begun to move toward intelligent direction; the functions of typical intelligent video surveillance systems include:
(1) Image recognition functions, such as recognizing a face image in a video image, identifying a specific person in the audio, and license plate recognition, target recognition functions of various industries, and the like.
(2) Image analysis functions, such as motion analysis in sensitive areas defined in the image range, and provide targeted recording, target tracking and alarm linkage functions.
(3) Security linkage related to business in the application field , such as interaction between various security sensors, controllers, audio and video recording, and monitoring alarms. Each application area can easily and flexibly define various related linkages on the monitoring software.
The fundamental difference between the new generation video surveillance management system and previous generations is that it is no longer limited to simply processing, transmitting, and controlling video signals. The core of the video surveillance system is to provide multimedia information (video, audio, data) based on IP networks. A comprehensive and complete management control platform.
The network multimedia monitoring system is based on the network, with the compression, transmission, storage and playback of digital video as the core, featuring intelligent and practical image analysis, and integrating the alarm system and access control system into one use platform.
It has triggered a technological revolution in the video surveillance industry and has rapidly attracted the attention of the security industry and users. Currently, network multimedia surveillance management systems have been widely used in multimedia video scheduling and command, network video surveillance and conferencing, multimedia webcasting, online teaching, Telemedicine and other aspects.
