11.4.3 Access control
Integrating a video management system with a facility’s access control system allows for facil-
ity and room access to be logged with video. For example, video can be captured at all doors
when someone enters or exits a facility. This allows for visual verification when exceptional
events occur. In addition, identification of tailgating events can also be made. Tailgating occurs
when, for instance, the person who swipes his/her access card knowingly or unknowingly
enables others to gain entry without having to swipe a card.
11.4.4 Building management
Video can be integrated into a building management system (BMS) that controls a number of
systems ranging from heating, ventilation and air conditioning (HVAC) to security, safety,
energy and fire alarm systems.
The following are some application examples:
> An equipment failure alarm can trigger a camera to show video to an operator, in addition
to activating alarms at the BMS.
> A fire alarm system can trigger a camera to monitor exit doors and begin recording for
security purposes.
