CEM Systems, part of Tyco Security Products, has released a DESFire two-door access controller.
Andrew Fulton, Business Development Director for CEM Systems, said: “With the threats of card cloning and the vulnerabilities of Wiegand controller signal cloning growing strong within the security market, CEM is delighted to announce the release of the new sPass reader and DCM 350 two-door controller with secure RS485 encrypted communications.”
CEM describe the sPass reader is a contactless smart card reader with 3DES (Triple DES) encryption. Available as a keypad or non-keypad option, the reader connects to the new DCM 350 intelligent two-door controller, which uses highly encrypted RS485 communications to the sPass reader. This the makers say eliminates the threat and vulnerabilities of controller signal cloning. The DCM 350 (Door Control Module) features an intelligent database for offline card validation. Operating in off-line mode, the DCM 350 can hold up to 200,000 cards. It can be configured to support two sPass readers on two separate doors with optional exit push buttons, or can be configured to support two sPass readers on a single door for entry/exit control. It is available in two options – the sDCM 350 supports serial devices or the eDCM 350 supports IP devices.
The company has also introduced a new contactless 13.56 MHz DESFire smart card to eliminate the threat of card cloning. Each card has different sets of encrypted keys that are securely stored on the card. CEM pre-personalises the card memory. The CEM DESFire smart card can hold up to 28 different security applications such as access control and cashless vending, and 32 files per application.
