Low power video surveillance system

Longwatch introduces XLP Low Power Video Surveillance System for remote areas.

Norwood, Mass., November 19, 2010—Originally developed for a major oil and gas company to monitor remote wells in North America, the Longwatch XLP Low Power Video Surveillance System can be applied anywhere a company needs video surveillance in remote locations far from utility electric power—such as water and wastewater pumping stations, lagoons, electrical transformers, power lines, offshore platforms, gates, fences, pipelines, etc.

Powered by solar cells and batteries, the system hibernates in a low-power standby mode until an external sensor, such as a motion detector or intrusion alarm, or a command from the central control room sends it a signal to wake up. The system immediately records a short “video alarm clip,” transmits it to a remote operator at a central HMI/SCADA system, and continues to record video on its disk until commanded to return to hibernation.

The XLP system can transmit its video clip to the control room using an RF data link, where it can be viewed using the Longwatch Viewer or integrated into the HMI/SCADA system. The Longwatch software makes minimal use of the available bandwidth, so it does not interfere with control and instrumentation data. The XLP can also use Ethernet, wireless, cellphone or satellite communications when power consumption or bandwidth is not a concern.

Once the operator sees the alarm video clip and message on the HMI screen, he or she can then command the Longwatch system to transmit live video, and remotely pan, tilt and zoom the site cameras to further investigate process or intrusion alarms. This allows the operator to see exactly what is happening at the remote location and determine the next course of action, such as dispatching a maintenance crew to repair a leak or summoning the local police to deal with intruders. Video enables the operator to quickly decide the best action to take to provide safety and reduce downtime or environmental impact.
