Cylon
The Cylon controller is built on the Open Supervised Device Protocol (OSDP), a communications specification developed by the Security Industry Association (SIA) and industry providers to encourage interoperability between access control devices and platforms. Cylon’s support of OSDP and its flexible open architecture enable the controller to exceed comparable devices’ life cycles. It also offers an easy upgrade process to further streamline usability and long-term value.
