Just as Industry has benefitted from being able to integrate wide ranging instrumentation, sensors and actuators within a common control philosophy; the same is now achievable within the field of Digital Security. Cause and effect logic, applied to autonomous systems such as CCTV, Intrusion Detection, Access Control, allows each system to become a sensor or actuator for the others. This further level of system intelligence means possibilities are limited by only imagination and budget. A simple example is would be to trigger a camera owned by an Autonomous CCTV system to move to a preset position – the related door – and record in high resolution for 10 seconds before and 30 seconds after a message was received from the respective door controller that forms part of the autonomous Access Control system.
