For example, a PSIM can use event data and correlative intelligence to raise alerts to operators only on events that are identified as important. When operators are not burdened with responding to false alarms or minor alarms, they can concentrate on real-time events. In addition, correlative intelligence and business logic simplifies the work of the operator, while providing data-driven consistency and removing human error and/or anecdotal interpretation from the response to events.
An example of a PSIM’s intelligence in action is in an airport setting, where multiple intrusion systems may be in use to protect the perimeter around a runway. Vibrations in the fence surrounding the runway from jet takeoffs might create a high volume of nuisance alarms.
A PSIM system can correlate the vibration alarm with video analytics of someone scaling the fence and flag the event as an alarm requiring response. The ability to set rules and correlate events greatly reduces false alarms and improves the workflow of the security personnel on staff, whether it’s the operator in the command center or a security guard who is being asked to physically check a location when an alarm sounds.
Another defining characteristic of a PSIM is the breadth of potential integrations. PSIMs can integrate not only with physical security systems, but also with other enterprise or operational systems present in a facility, such as a geographical information system (GIS).
A utility company may, for example, use GIS integration to view map information, detailed floor plans, heat maps and perhaps even crime statistics in the area in which an alert is received. Mass notification systems may also be integrated with a PSIM.
In such a scenario, the operator might receive notification of an impending hurricane through an ATOM feed, view the forecasted storm track and identify facilities in its path with GIS maps, and then send automated warnings via multiple channels to employees in these facilities. This could all be accomplished by the operator through the single PSIM interface.
Multiple Uses for PSIMs
PSIM solutions have traditionally been implemented in such environments as public utilities, government and nuclear facilities, mainly due to the solution’s ability to provide situational awareness and a higher level of security. The PSIM’s design center is that of an operator receiving multiple alerts and alarms, understanding situations based on information from the PSIM and then taking action, which is a good match for these environments.
