3 Terms, Definitions and Abbreviations
3.1 Terms and Definitions
For the purpose of document, the following terms and definitions apply.
3.1.1
video surveillance network system for public security
it refers to the integrated network system used to maintain national security and social stability, to prevent and crack down illegal and criminal activities, which is based on integrated application of video and audio surveillance, communication, computer network, system integration and other technologies; it is able to fulfill the interconnection, intercmmunication and intercontrol between different devices and between systems, and has such functions as information collection, transport, switch, control, display, storage and processing
3.1.2
data of network system
it refers to information transport, switch, control in network system, mainly include alarm information (analog switch quantity alarm and data protocol alarm), video information (analog video signal and digital video signal), audio information (analog audio signal and digital audio signal), device control information (serial port data and IP network data), device management information (serial port data and IP network data) and other information
3.1.3
front-end device
it refers to the device of information collection, coding/treatment, storage, transport and safety control, installed at the site of monitor and control in network system
