Nova Scotia Bridges Deploy Video Surveillance from PureTech Systems (6/21/12)
PureTech Systems installed its wide-area video surveillance system on both the Macdonald and the MacKay Bridges. The bridges, maintained and operated by Halifax Harbour Bridges (HHB), accommodate almost 34 million crossing each year.
The bridges provide transportation between Halifax and Dartmouth in Nova Scotia and are a critical part of the area's business and social livelihood. HHB's mission is to provide safe, efficient, reliable cross-harbor transportation infrastructure at an appropriate cost. Part of that mission included a security upgrade, including more than 100 surveillance cameras augmented with intelligent video analytics for detection and analysis.
The system includes integration of both fixed and pan-tilt-zoom (PTZ) camera types from companies including Bosch and FLIR. Nova Scotia's changing weather conditions and the unique aspects of a bridge environment drove decisions to use multiple technologies including thermal imaging and short- and long-range camera options.
In addition to video surveillance, the new system includes integration with the Johnson Controls P2000 access control system and accommodates the ability to manage both bridges simultaneously or address each independently. It also includes point-and-click camera control and geospatial map-based user interface. Although the initial deployment focuses on security of the bridges and surrounding area, the system will also have the ability to aid in safety situations, such as detecting dropped objects or stopped vehicle.
