Geovision 55-RE251-110 125KHz RFID Reader
Overview
The Geovision 55-RE251-110 is a 125KHz RFID reader designed for proximity-based access control integration with Geovision GV-series access control panels. This reader handles standard low-frequency RFID credentials (cards, fobs, wristbands) and connects directly to the panel's reader input, eliminating the need for separate authentication infrastructure. Deploy this where you need fast, non-contact credential presentation — loading docks, server rooms, emergency exits, or any door requiring quick identity verification without keypads or biometrics.
Compatibility
The 55-RE251-110 pairs with Geovision GV-series access control panels that support 125KHz reader inputs. Confirm your specific panel model accepts standard Weigand protocol (26-bit) reader connections before ordering. The reader connects via standard reader cable to the panel's input terminal — no special drivers or software configuration beyond standard Geovision panel setup.
Installation Notes
Mount the reader within 4–6 inches of the credential presentation area for reliable detection. Avoid placing metal objects or electrical equipment directly behind the reader face, as these degrade RF coupling and increase read time. Ensure the panel's reader input is powered and configured to accept Weigand data before testing. Wire the reader using shielded twisted-pair cable to prevent EMI-induced read failures in noisy electrical environments.
