Control Microsystems Inc. (CMI) and Longwatch offer the SCADA host platform, ClearSCADA, to provide video surveillance of remote processes and assets. Existing industrial networks can conveniently and cost-effectively transmit video images over the SCADA communication infrastructure.
Control Microsystems’ ClearSCADA host platform can be integrated with the Longwatch Video Surveillance Platform and Video Historian Platform, along with IP surveillance cameras, as a solution to capture and convey important security information for critical infrastructure. The video surveillance uses Modbus protocol and is event-driven to conserve bandwidth. The Longwatch system continuously takes and stores video locally. When motion is detected, an alarm is raised, and a video snippet is attached to the alarm message and sent to the central control site, showing what happened before and after the event. Through a graphic display in ClearSCADA, operators are able to view what is occurring on-site, preventing the needto send someone to investigate the alarm.
