The DHI-ASC3202B provides a single-interface access control solution that is accessible anywhere there is an internet connection. The controller has two modes: the main mode and the sub mode. The main mode allows the controller to serve as central management for all access control devices in a building or area. The sub mode allows additional controllers to be pooled into the main controller device list and networks card readers together. Each controller controls up to two (2) doors but can be scalable up to 40 doors. The controller can be powered via PoE+ (IEEE802.3at), added to DMSS for remote door control, and ONVIF compliant to allow for third-party reader management.
