Integriti's high-level interface with Milestone's ACM is IP-based and bi-directional. The ACM integration allows Milestone to be the single master 'head end' security management platform, whereby Integriti functions as an access control and security sub-system. Cardholder information, alarms and events, as well as door and area statuses in Integriti are sent in real-time to Milestone. Operators are therefore empowered to effectively manage their security operation by seamlessly monitoring Integriti alarm and access points through Milestone. Operators may also unlock and lock doors, and control areas with the added ability to associate doors and areas to cameras in Milestone, thus facilitating efficient situational awareness and immediate visual verification of alarms.
