One of the first images engineers at the Madison Water Utility (MWU) in Madison, Wisconsin, saw when they were installing their new Video Surveillance System from Longwatch was a platoon of uniformed soldiers, carrying M16 machine guns and creeping across the property. The water plant survived that “invasion” and now monitors 32 remote sites with video cameras that transmit over a low-speed wireless network to Wonderware HMI/SCADA operator interfaces in the control room.

The Video Historian extension for Longwatch’s Video Surveillance System enables users to acquire and store video clips linked with process and manufacturing variables such as time of day, camera number, batch step, machine ID and other control system tags. Much like a process historian that stores information about processes, the Video Historian archives video that documents procedures in batch applications, provides visual proof of regulatory compliance, monitors machinery, observes operator actions, and helps improve quality, reduce downtime and avoid costly losses.
