Boston’s Logan International Airport is working with Atlanta-based VistaScape to implement a new perimeter security system based in part on VistaScape software.

The Massachusetts Port Authority said the system, which now is in a pilot and testing phase, is designed to detect threats automatically and reduce response times to those threats.

VistaScape’s SDMS software program is integrated with infrared cameras from FLIR Systems. The system is designed to provide early warning coverage at all hours in all weather conditions. Its proprietary algorithms are used to identify abnormal movements or objects and alert airport authorities. Alerts, including real-time positioning of threats, can be forwarded directly to the PDAs carried by State Police security personnel.

The implementation is part of Logan’s increased security efforts since the terrorists attacks of 9-11-01.
