A Major Gas Pipeline Company Requires Redundant Video Recording A major gas pipeline company needed a surveillance solution for monitoring remote pumping stations from a central location. The requirements included control of pan tilt and zoom (PTZ) cameras as well as video recording at each field station and at the central location.  IPVideo Corporation’s proposal of a two-tier video surveillance design fully meets the customer’s requirements by providing for redundant recording at each remote location and also at the central location. Viewing of cameras will also be provided at the central location in a Security Operations Center (SOC) style display.   Since the only components shared by the remote systems and the centralized system are the cameras/video servers and the local network at each pumping station, this two-tier system provides the redundancy and reliability required by this application. The built in remote system control includes the ability to force a full power cycle reboot of any part of the system enabling remote maintenance and problem correction as long as the WAN link is functional. Manual operation of the PTZ cameras from the command center (SOC) can temporarily interrupt the automatic pre-defined camera patrol of any PTZ camera. Once manual control returns to an inactive state, control will automatically be returned to the pre-defined patrol operation for each camera. Since the available bandwidth is a limiting factor for the operation, the IPVideo increases reliability by making two parallel camera connections with one of those connections being transmitted over the WAN for centralized recording and viewing and the other being restricted to the individual pumping station’s LAN for local recording and viewing.  This design also means that an outright failure of a WAN link does not compromise local recording.   Each remote location includes a DynaView/Edge-8 NVR with 1TB of storage capable of recording 24/7 at 3 FPS CIF resolution for 30 days. The cameras being used are Pelco Spectra series PTZ cameras connected to Axis 234Q Video Servers. A DynaView Enterprise-50 NVR with 8TB of storage is located at the central location providing for continuous recording of as many as 50 cameras for up to 60 days at 2 FPS CIF resolution. There is a high performance viewing station and twin 28” high resolution LCD monitors at the central station. These provide for live viewing of up to 32 or more cameras, multiple views, syslog views of all remote system power status, and archive playback.
