Geovision 520-RKR1355-000 Desfire Osdp Smart Card Reader

Product Description

The GEOVISION 520-RKR1355-000 is a DESFire OSDP smart card reader designed for access control applications. It reads MIFARE DESFire encrypted credentials and communicates over the Open Supervised Device Protocol (OSDP), a modern bidirectional serial standard that supports supervised wiring and encrypted reader-to-controller communication. This reader is installed by security integrators and low-voltage technicians as part of a broader access control system, typically at door entry points in commercial or institutional facilities.

This reader is suited for commercial access control deployments where credential security and controller interoperability are priorities. OSDP-capable controllers support two-way communication with this reader, enabling real-time status monitoring and firmware updates over the RS-485 bus. DESFire card technology provides AES-based encryption at the credential level, making it appropriate for higher-security installations such as office buildings, healthcare facilities, and government sites.

Key Features

• DESFire credential support with AES-based encrypted card communication
• OSDP protocol for bidirectional, supervised RS-485 communication with access controllers
• Designed for commercial and institutional access control door deployments
• Sold as an individual unit (each)

Compatibility

Designed as an OEM-style replacement or new-installation smart card reader for OSDP-compatible access control panels and controllers supporting DESFire encrypted credentials.

Installation Notes

Installation should be performed by a licensed low-voltage or security systems technician in accordance with applicable local codes and the controller manufacturer's wiring specifications. Power down the access control panel before wiring the reader to the RS-485 bus. Verify OSDP addressing and baud rate settings on both the reader and the controller before commissioning. Do not connect or disconnect wiring while the panel is energized.
