Chapter 1 Introduction
The fingerprint reader can work with GeoVision access controllers and GV-ASManager
software to create a complete access control system. Three types of operation modes are
supported: Card + Fingerprint, Fingerprint Only, and Card Only.
Card + Fingerprint Mode
With the fingerprint reader only, you can enroll and manage users using the supplied
Manager Enroll Card and Delete Card, along with optional MIFARE cards.
The fingerprint templates are stored in the user card. The user gains access by scanning
both his/her finger and the card. The reader compares the presented finger with digital
template stored in the card. When the finger is successfully authenticated, a signal is sent to
activate the door relay of the controller.
Fingerprint Only Mode
The fingerprints are enrolled through a fingerprint reader installed on the GV-ASManager
server via RS-485 or a USB cable, or through a fingerprint reader via network. The
fingerprints are then distributed through GV-ASManager to the fingerprint readers installed
on GeoVision access controllers.
Card Only Mode
The mode requires users to present their cards only to be granted access.
Note: GV-GF1921 / 1922 / 1922 V2 can also work as a standalone device. For details, see
Chapter 6 Standalone Mode.

one.
3.1 Enrolling Fingerprints
There are two options for enrolling fingerprints: locally and remotely.
To enroll fingerprints locally, connect a GV-GF1911 / 1921 / 1922 / 1922 V2 reader to GV-
ASManager and register fingerprints at the GV-ASManager’s site.
To enroll fingerprints remotely, first enroll blank fingerprints for a user in GV-ASManager.
The user can then register fingerprints on a connected GV-GF1921 / 1922 / 1922 V2 reader
using a given card. This function is helpful when the user is not at the GV-ASManager’s
location.
Note: Local fingerprint enrollment at the GV-ASManager's site requires a separate GV-
GF1911 / 1921 / 1922 / 1922 V2 reader.
