The iSentry rules engine plays the role of an operator, insofar as it can autonomously decide if an alert should be forwarded as an alarm, or dismissed. This decision is based on factors like the type and number of objects present in an alert scene, as well as the time of day, and likelihood of a classification. The inherent risk of automation in this regard is largely mitigated by several logic mechanisms including targeted rules, where rules are only applied where their outcome is highly certain.
Where a rule is not applied or the rules engine is unable make this decision, the alert is simply forwarded to an operator for further investigation. At sites with no control room, and no operators, the rules engine can be used to identify important or potentially dangerous situations and then notify the system owner of their presence, adding monitoring to otherwise unmonitored video.
