Johnson Controls has added to its CEM Systems range of access control products with the launch of the DCM200 door control module. Designed to directly interface with CEM Systems’ AC2000 access control software versions 10.2 or higher, the DCM200 is a two-door controller which is able to support a mix of up to four Wiegand or CEM Systems approved Open Supervised Device Protocol (OSDP v2) smart card readers.
OSDPv2 is a secure access control system protocol standard developed in the United States by the Security Industry Association for peripheral devices. With secure AES 128 encryption, it provides bi-directional communications for connecting OSDPv2 compliant readers to DCM200 control panels and with its security features, eliminates the threat of Wiegand signal cloning. As for other cyber security credentials, the DCM200 uses secure TLS v1.2 communications to the host server and a Secure Element on-board for key storage, updates and boots, while offering support for 802.1x network authentication.
As for install, the installer configures the IP address by selecting DIP switches using DHCP or auto-configuration. When connected to an Ethernet network, the DCM200 will then self-configure and receive the database of up to 50,000 cardholders in under 2 minutes.
Designed with the end-user and installer in mind, the DCM200 comes with a dashboard which can assist with local and remote trouble-shooting, as well as the monitoring and configuration of the DCM200 and any equipment connected to it. The dashboard provides operators with visual indicators and data on the status of the network, power, doors, inputs/outputs and database status and lets operators remotely configure network settings and set limits for outputs, such as read heads, locks and auxiliary outputs.
Using 32-bit processors, the DCM200 gives off-line verification and decision making at the point of entry when host communication is not available, while bi-directional control on two doors can be achieved when OSDPv2 compliant readers are used in an entry/exit configuration.
With the ability to support any combination of Wiegand or OSDPv2 readers, the DCM200 offers a future-proof solution for end-users who may wish to migrate from Wiegand readers to more secure readers, the product firm adds.
