Video monitoring system status and future trends

Video surveillance system is an integral part of the security system, it is a comprehensive system of prevention capabilities stronger. Video Surveillance with its convenient, intuitive, content-rich and is widely used in many occasions. In recent years, with the computer, networking, and image processing, the rapid development of transmission technology, video monitoring system technology has made great progress.

A video monitoring system status In the domestic market, the main launch of the digital control of the analog video surveillance and two types of digital video surveillance products. The former technology is already very mature, stable, and the practical engineering application, are widely used, especially in large and medium-sized video surveillance project of particularly wide; the latter is a newly emerging computer technology and the core image video compression The new video surveillance system, which solves some drawbacks of the simulation system, the rapid rise, but still need further improvement and development.

Present, video monitoring system is in NC simulation system and the application of digital systems and gradually mixed transitional phase to digital systems.

1, digital signal control of analog video monitoring system control digital signal into analog video surveillance system microprocessor-based video switching control with PC-PC-based multimedia management and implementation of the matrix and the host of the switching control two types of multimedia management system.

1-1, microprocessor-based video switching control with media PC-type management is the microprocessor’s 80 years, video surveillance system microprocessor firmware using the development of matrix switchers, scattered all the original centralized video monitoring system micro hardware, such as video switching, control and other functions on the front of the set with a machine dealing with, is a breakthrough technology.

Owned by the host microprocessor of the matrix PC, graphics management software to achieve the following functions:

into a single workstation for video surveillance, access control, internal communication and alarm comprehensive control, etc. (Note: can only provide a simple, system control functions can be enhanced user interface, but can not replace the host matrix Security Configuration and programming skills);

Renyiyitai workstation via the network, control other workstations connected to the host matrix, alarm devices, complete video switching, PTZ, Shot Control and alarm linkage, etc.;

can host software on the number of matrix and alarm interface software module control.

1-2, PC-based implementation of the matrix host switching, control and management system for multimedia PC-based video surveillance system uses software designed to achieve the camera to Monitors Video matrix switching, PTZ and lens control, alarm device through the serial port to connect the alarm information automatically through the programming video switching, PTZ control, alarm linkage, alarm recording, and other control functions. PC-system can make full use of the resources, so that video monitoring system with the development of computer technology advances, while its open structure allows for more features and many other systems, such as with the fire alarm system, import and export management systems, building automation systems integration to interact.

1-3, NC strengths and weaknesses of analog video surveillance system with the microprocessor, computer functionality, performance enhancements and improved multimedia technology, system functionality, performance, reliability, structural way, were all great changes have taken place, the composition of video surveillance system is more convenient and flexible, and other technical systems tend to standardize interfaces, human-machine interface more friendly. However, video surveillance system in the form of information flow has not changed, still the analog video signal, the system’s network structure is primarily a single function, one-way, set the total way of information gathering network, media-specific features, so the system despite has developed to a very high level, there is little potential to be, its limitations still exist, to meet the higher requirements Digital Is the only way.
