This work proposes a Cyber-Physical System (CPS) for protecting Smart Electric Grid Critical Infrastructures (CI) using video surveillance while remotely monitoring them. Due to the critical nature of Smart Grid, it is necessary to guarantee an adequate level of safety, security and reliability. Thus, this CPS is back-boned by a Time-Sensitive Network solution (TSN) providing concurrent support for smart-video surveillance and Smart Grid control over a single communication infrastructure. To this end, TSN delivers high-bandwidth communication for video surveil-lance and deterministic Quality of Service (QoS), latency and bandwidth guarantees, required by the time-critical Smart Grid control. On the one hand, the CPS utilizes High-availability Seamless Redundancy (HSR) in the control subsystem via Remote Terminal Units (RTU) guaranteeing seamless failover against failures in Smart Grid. On the other hand, the smart video surveillance subsystem applies machine learning to monitor secured perimeters and detect people around the Smart Grid CI. Moreover, it is also able to directly interoperate with RTUs via MODBUS protocol to send alarms in case of e.g. intrusion. The work evaluates the accuracy and performance of the detection using common metrics in surveillance field. An integrated monitoring dashboard has also been developed in which all CPS information is available in real time
