Video surveillance system has been set up in new-built or reformed smart substations for safe operation, fire alarm and assets safety. In this paper video surveillance system has been developed for operation, especially for programmed operation of smart substation. Therefore, video image information besides conventional signals such as telemetry, remote signal, telecontrol, and remote regulating has been integrated in the novel integrated system to assist safety operation. The system architecture has been divided into three components and introduced in this paper firstly. Communication protocol has been developed for exchange information between integrated SCADA system and video surveillance system.
