The Longwatch Video Historian now features Canary Labs’ Trend Historian and Trend Link software, enabling users to link video with plant data.

This is the result of a bi-directional OEM agreement between Canary Labs and Longwatch.

Together, the two systems archive all relevant information – video and real-time data – from a process or automation system, making it easier for plant operators and engineers to analyse events, alarms and actions.

When video cameras monitor process or automation operations – such as assembly lines, inspection stations, machine tools, pumping stations, tanks or similar systems – footage from the cameras is stored along with real-time data from the process.

If an alarm occurs, or operators want to analyse problems with a system, both the archived trend data and video can be simultaneously replayed and displayed using the Longwatch Viewer software.

This allows operators and engineers to see all of the pertinent process data from the historian and view footage of the process equipment at the same time.

The Longwatch system can acquire footage from both analogue and digital cameras throughout the plant.

Footage can be sent over existing plant networks, or wireless or cellular links to a central server in the control room, where it can be viewed on HMI/Scada workstations.

Footage 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 synchronisation of trend charts and video, can interface to other historical data archives using OPC-HDA.

Similarly, the Canary Labs Trend Historian collection engine can obtain real-time data directly from PLCs, RTUs, data-acquisition systems, PC-based control systems and other smart systems via OPC interfaces.

Video footage makes analysing past events and trends much easier than simply looking at raw data and reports on a screen.

The Canary Labs historian and trending component is part of the Starter Pack of Longwatch’s Video Historian software.
