The Longwatch Video Historian enables users to link video with plant data. The Canary Labs Trend Historian and Trend Link software systems archive video and real-time data from a process or automation system, making it easier for plant operators and engineers to analyze events, alarms and actions. The video system can acquire video from both analog and digital cameras. The data can be sent over existing plant networks, wireless or cellular links to a central server in the control room, it can be viewed on HMI/SCADA workstations. The video can be viewed live, attached to an alarm message as a short "snippet," or archived in the server along with real-time process data. Canary's Trend Link chart object, integrated into the Longwatch Video Historian for automatic visual synchronization of trend charts and video, can interface to other historical data archives using OPC-HDA. The Trend Historian collection engine can obtain real-time data directly from PLCs, RTUs, data acquisition systems, DCSes, PC-based control systems, and other smart systems via OPC interfaces.
