Description
Technical field
The present invention relates to the safety monitoring equipment technical field, especially relate to a kind of portable digital audio and video acquisition devices.
Background technology
The video monitoring collecting device is the indispensable means of effectively carrying out security monitoring and humane data being put on record, and its forgone text and still image such as is distorted easily at all deficiencies.
In recent years international anti-terrorism situation, development of the West Regions and Invigoration of Northeast China, 2008 Olympic Games and Shanghai World's Fair, domestic urbanization and Instant City construction, safe city construction, certain applications field security incident this several respects that take place frequently have consisted of the main active factor of safety monitoring equipment and technical development.
Current existing safety monitoring equipment and technology Main Problems have: 1, the high-tech product research and development ability is low, and the many dependence on import of new product and core technology fail to form orderly system of scientific and technical innovation; 2, existing safety monitoring equipment and technological system are not suitable with integrated, digitlization, networking, intelligent requirements; 3, the safety monitoring technology back-up environment is poor, and standard lags behind, and product detects, the authentication evaluation measures is lower; 4, safety monitoring equipment and technology or network operation management is lack of standardization, and it is unsound to connect the mechanism of dealing with emergencies and dangerous situations; 5, safety monitoring technology fundamental research is weak, the performance of restriction safety monitoring technology usefulness.
The trend main manifestations of safety monitoring equipment and technical development is: 1, digitlization, networking, intellectuality, integrated be direction; 2, progressively establish and improve the security protection system of scientific and technical innovation; 3, greatly develop 4C technology (communication/computer/control/multimedia display technology), intelligent building 5A system and Intelligent transport ITS system; 4, network technology and multiple security and guard technology are implemented integrated research and development; 5, create and improve comprehensive safety service network at different levels.Social security Dynamic Monitoring System, city pre-alarming system and safety urban construction are the new opportunities of domestic security protection industry.
For corresponding with computer, traditional analog machine has begun to change to digital device; Numerical data has begun to transmit easily and manage; Can enlarge range of application by other digital product of safety supervisory network equipment connection; The demand of teletransmission is also increasing, and this shows that Video Supervision Technique enters digital Age comprehensively.The development of the network information; Many buildings have possessed local area network (LAN) and wide area network; It is upgrade-systems under PC control that many requirements are arranged; Image processing has many elasticity with PC; Multiple data preservation hardware (hard disk, backup CD etc.) development is very fast, and condition has been created in the development that develops into Video Supervision Technique of infrastructure.
The Video Supervision Technique development experience simulation monitoring, digital supervision to the large scale network monitoring development.Each part of video monitoring system---front end video acquisition, transmission of video, videograph, control, display part technical development are very fast.
Many and the dispersion of control point quantity; Network Construction makes Network Video Transmission become economical, feasible; The demand of mass data transfers and storage; Equipment control importance strengthens even surpasses image monitoring itself; The manager is mobile to strengthen; Construction, wiring cost costliness require simplified wiring to reduce investment; Information security is subject to common concern.The demand in market calls Video Supervision Technique to change.
The key technology of video monitoring mainly contains video acquisition compression, vision signal is transmitted reliably, the information storage is called intellectuality and the centralized management of system.
The Video Supervision Technique developing direction is that distribution collection centralized management, high quality image compression processing, open standard unified interface, unified certification guarantee safe, user-friendly for operation, and function is integrated, structural module and transmit diversity.
Summary of the invention
