IEC 62676-3:2013规定了视频监控系统（目前称为CCTV）应用中模拟和数字视频接口的物理、电气和软件接口（非IP）规范。视频接口用于连接和传输监控视频、音频和控制信号。本国际标准严格适用于视频监控系统。本标准以广播电视标准和其他标准为基础，定义了模拟和数字视频接口的最低要求，以满足VSS的要求、互操作性和事实实践。

IEC 62676-3:2013 specifies physical, electrical and software interface (non-IP) specifications of analog and digital video interface in video surveillance systems (so far called CCTV) applications. Video interfaces are used both for connection and transmission of surveillance video, audio and control signals. This International Standard applies strictly to Video Surveillance Systems. This standard is based on broadcast television standards and other standards, and it defines the minimum requirements for analog and digital video interfaces to meet VSS's requirements, interoperability and de facto practice.
