Concerned About Access Reader Security and Encryption?

When your customers require OSDP for their next install, you’ll be ready. In addition to Wiegand readers, all DMP 734 Series access control modules support OSDP readers, making them among the most secure access control modules available.

What is OSDP?
OSDP stands for Open Supervised Device Protocol — it was developed by the Security Industry Association in 2011 and is now widely considered the gold standard for access control installations. For increased security, OSDP supports high-end 128-bit AES encryption to more effectively prevent the interception of data between modules and readers.

In addition to the selection of Wiegand card readers, all of the Farpointe readers that DMP offers are fully tested and compatible with our OSDP-capable modules. To connect to compatible OSDP readers, DMP access control modules use RS-485, which provides bidirectional two-way communication to acknowledge messages between the reader and module. This two-way supervised communication allows the system to monitor readers and more easily diagnose issues remotely. Also, with standard wiring, it extends the range of data transmission. With the proper RS-485 cable, the range can expand even more, up to 4,000 feet.

Financial and government customers were the first to express interest in DMP developing a product that transmits data using OSDP protocol. As the demand for OSDP expands to other applications. DMP along with Farpointe are in a unique position to meet demand by serving customers better.

16-Character Customizable Secure Key
Namely, only DMP allows customers to create their own alphanumeric secure keys, which can contain up to 16 characters. This customized secure key permanently bonds OSDP readers to modules, further protecting access control systems against tampering and reader swapping. In the field, it also gives customers greater flexibility, Norris added.

Since DMP’s modules allow users to create their own secure key, this means you can swap out modules as needed without having to swap out the reader and still be able to connect encrypted.

No Price Increase
There is no price increase to the 734s to take advantage of OSDP. The price points on the 734s will remain the same as what your used to.

Along with increased security and advanced functionality, OPDP delivers other benefits. To learn more, please review the spec sheet (LT-1208) for DMP’s access control modules. If you have any questions, please contact DMP Inside Sales at 877-757-4367 or at
