CEM Systems intelligent IP and Serial door controllers offer a high level of system resilience and intelligence for use with the AC2000 access control system.

Did you know that CEM was first to market with its Power over Ethernet plus (PoE+) door control!

DCM 400 Four-Door Intelligent Encrypted IP Controller

The CEM Systems DCM 400 (Door Control Module) is an intelligent four-door controller designed to directly interface CEM Systems AC2000 access control system (version 10.2 and higher) with Wiegand or CEM Systems approved and supplied Open Supervised Device Protocol (OSDP v2) smart card readers.

DCM 200 Intelligent Two-Door IP Controller

Intelligent True Two-Door Controller - The DCM 200 (Door Control Module) is an intelligent two-door controller designed to be highly secure and directly interface with CEM Systems AC2000 access control software (version 10.2 and higher). It also supports up to four Wiegand or CEM Systems approved Open Supervised Device Protocol (OSDP v2) smart card readers. These OSDPv2 compliant readers can be used (Entry/Exit configuration) for bi-directional control on two doors.

DCM 350 Encrypted Two-Door Controller For sPass Readers

The CEM DCM 350 is a low cost, intelligent two-door controller range that interfaces to CEM sPass DESFire smart card readers (sPass).  By utilizing encrypted RS485 serial communications between the DCM 350 controller and the sPass reader, the threat of Wiegand controller signal cloning is effectively eliminated.

eDCM 330 Power Over Ethernet Two-Door Controller

The CEM eDCM 330 is a low cost, two-door controller designed to interface third-party read heads with the CEM AC2000 range of access control systems.  It utilizes Power over Ethernet Plus (PoE+) connectivity and has the benefit of eliminating the need for an external local mains power supply at the door. 

AC2000 (RTC) Ethernet Controller

The AC2000 RTC (Real Time Computer) is a software controller required for use with Ethernet based CEM readers and devices as part of the core AC2000 access control system and the AC2000 Airport access control system.

AC2000 Super RTC (sRTC)

The AC2000 super RTC (sRTC) is a PC server hardware unit designed to host multiple AC2000 Ethernet Reader Controllers. The sRTC hardware unit is capable to host up to a maximum of 2048 access doors or addressed AC2000 devices, this total is equivalent to eight standard RTC units.

Ethernet Communications Module (ECM)

The ECM (Ethernet Communication Module) is a powerful serial to Ethernet converter that enables CEM serial communication devices to connect to the CEM AC2000 access control system via an Ethernet LAN.
