1向数字化、网络化、智能化发展视频监控技术的发展历程是:模拟→数字→网络→IP智能与集成,如图1所示。监控的本质需求是为了满足用户的实战需要,如有效取证、事态控制和运营管理维护能力等。目前,许多监控系统规模越来越巨大,结构越来越复杂。系统过于复杂,模拟的、数 1 to digital, networked, intelligent development Video surveillance technology development process is: analog → digital → network → IP intelligence and integration, as shown in Figure 1. The essential requirement of monitoring is to meet the actual needs of users, such as effective forensics, event control and operation management and maintenance capabilities. At present, many monitoring systems are becoming more and more massive and the structure is getting more complex. System is too complex, analog, and number
