Video Management System Upgraded

The Longwatch Video System Version 5.2 upgrades include a value edition of the console recorder, a low-power XLP version of the video system that delivers surveillance in remote areas with limited power budgets, and improved database functions.
The Longwatch Console Recorder acts like an airplane’s flight recorder, because it stores all the screens that operators saw before, during and after a critical event, and it records every action the operators took during that time. Playing back the operator’s display can help solve problems faster and more accurately, because the display correlates other plant data in an intuitive way. The value edition of the console recorder allows users to install the terminal monitoring software at a low entry cost.
The value edition of the console recorder monitors and records all activities at up to six operator consoles, including screen displays and operator actions via the keyboard and mouse, so engineers and supervisors can replay an “event.” By replaying the event, engineers and supervisors can see what the operators saw and did, and determine if the operators were given the proper information and took the appropriate actions. The recorded data can be saved and used for training purposes, process improvement, justification to various regulatory bodies the correct actions were taken, and detailed “post mortems” of events.
When part of a Longwatch Video Surveillance system, the enterprise edition of the console recorder can also synchronize with video taken in the plant from multiple cameras, and with real-time and historical process data (including trends and alarms) from existing process automation systems, This allows engineers and supervisors to completely reconstruct an event, using video from the plant, data from the historian, and the operator displays and actions from the console recorder.
The value edition of the console recorder captures data from six operator terminals, but it can be upgraded later to the Enterprise Edition Console recorder and Video Historian. Click here for a free demo version.
Version 5.2 also includes an extreme low-power (XLP) option, where video cameras and the Longwatch Remote Video Engine can operate from solar power and batteries. The XLP system “hibernates” until a signal from an intrusion alarm or motion detector or operator wakes it up. The system then begins recording live video immediately, sends a short “alarm clip” to a remote operator at a central HMI/SCADA system, and continues to record data until commanded to return to hibernation.
The XLP system works well at well sites, pumping stations, pipelines, offshore platforms or other remote areas where 120Vac line power is not available. These sites typically have some form of RF data link, and use solar power for their instrumentation. The Longwatch XLP system uses very little power during hibernation, yet provides these remote sites with video monitoring capabilities. Longwatch communicates from the remote station using virtually any network provided, ranging from low-speed radio modems to satellite and cellular links.
