BAIJIAN - Third party testing organization
In order to implement the national technical and economic policies、 standardize the engineering design、 construction、 and acceptance of civil closed circuit monitoring television systems (hereinafter referred to as the system)、 achieve advanced technology、 economic rationality、 safety and applicability、 ensure quality、 energy conservation and environmental protection、 this specification is formulated. This specification is applicable to the design、 construction、 and acceptance of new construction、 renovation、 and expansion projects of closed circuit television systems primarily aimed at civilian surveillance. 1. 0 The system should adopt digital、 networked、 intelligent、 and high-definition technology. 1.0.4 The design、 construction、 and acceptance of civil closed-circuit monitoring television system engineering should not only comply with this specification、 but also comply with the current national standards. 2 Terminology 2.0 1. Closed circuit monitoring television system is a wired system that uses video and audio technology to display real-time images or play sound of the monitoring location、 and record on-site images or sound. 2.0 2. Surveillance& The control sub center is a node in a CCTV system that collects、 processes、 and shares information at a certain level or area. Used to receive、 display、 record、 process video information、 status information、 etc. from the front-end and various subsystems、 and communicate with the higher-level monitoring center、 accepting management from the higher-level monitoring center. 2. 0.3 Surveillance& The central control room of the CCTV system. Used to receive、 display、 record、 and process video and audio information、 status information、 etc. from the front-end、 subsystem、 and monitoring sub center、 and issue control commands to relevant equipment in the system. 2.4 Intelligent Video System (Ivs) utilizes technology that establishes mapping relationships between images and image descriptions、 enabling computers to understand the content of video images through digital image processing and analysis、 obtain real-time key information、 monitor and search for specific behaviors、 discover anomalies in the monitored images、 and issue alerts and provide useful information in the fastest and best way possible. 2. 0.5 Recording System The recording system mainly stores the images or sounds collected by the video and audio acquisition system for easy search and playback. 2.0 The ability of 6 image resolution picture resolution to characterize image details、 often referred to as source resolution、 is typically represented by the number of pixels in both horizontal and vertical directions
