Frequently Asked Questions - GV-GF1922 Geovision

How do I enroll fingerprints on the GV-GF1922?

Fingerprints can be enrolled locally via a connected reader to GV-ASManager or remotely by first creating blank fingerprints on the server. For local enrollment, connect the reader to GV-ASManager via LAN, go to Personnel > Users, select a user, click the Features tab, choose a finger, and select Enroll Fingerprints. Scan the finger twice. For remote enrollment, create blank fingerprints and upload to the reader; the user then presents a card and scans their finger on the reader.

How do I connect the GV-GF1922 to a controller?

The GV-GF1922 supports TCP/IP connection. Connect the reader to the network via Ethernet, then access its web interface to set the IP address. On the GV-AS Controller web interface, go to Extended Reader, enter the reader's MAC address, select a door function, and click Submit. Alternatively, configure the controller's IP on the reader's Other Settings page.

What is the maximum distance for Wiegand and RS-485 connections?

For models supporting Wiegand (GV-GF1911/1912), the maximum distance is 30 meters (98.43 ft). For RS-485 (GV-GF1911/1912), the maximum distance is 600 meters (1968.50 ft) using a twisted pair of 24 AWG wires. The GV-GF1922 uses TCP/IP and is not limited by these distances as long as the network reaches.

How do I reset the GV-GF1922 to factory defaults?

Locate the Default Button on the rear panel. Use a pin to press and hold the button until the purple LED flashes red and blue. When you hear a beeping sound, release the button. The light will return to a steady purple, indicating the device has been reset to factory defaults.

What do the LED indicators mean?

Solid blue: ready; flashing blue: waiting for fingerprint/card during enrollment; green flash: access granted; red flash: access denied; red flashing: waiting for deletion; purple solid: not connected to controller (GV-GF1922); yellow flash: fingerprint not found; white solid: IP/gateway mismatch.

Can the GV-GF1922 work without a controller?

Yes, the GV-GF1922 supports Standalone Mode. Enable it via the web interface under Other Settings > Local mode configuration. Connect input/output devices (door sensor, exit button, door lock) using the provided data cable. Enrollment and deletion are done using the Manager Enroll/Delete cards.

What cards are supported for Card + Fingerprint mode?

The reader works with GeoVision GV-AS ID F cards and tags (serial numbers starting with 'F'). Third-party MIFARE cards can be used in Card Only mode or for standalone enrollment. In Card + Fingerprint mode, set card identification to GeoVision Card (UID) or GeoVision Card (GID) via the web interface.

How do I delete a user from the GV-GF1922?

For Card + Fingerprint mode, use the Manager Delete Card. Present the Delete Card to the reader (red blinking), then present the user card twice. The fingerprints stored on the card are erased. For Fingerprint Only mode, deletion is done via GV-ASManager by selecting the user and removing their fingerprints.

How do I upgrade the firmware on the GV-GF1922?

Firmware can be upgraded via the web interface or GV-IP Device Utility. Download the latest firmware from the GeoVision website. On the web interface, go to Firmware, select the file, and click Upload. The reader will reboot automatically after completion. Alternatively, use the utility to select the device and firmware file.

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.

Chapter 3 Fingerprint Only Mode

The Fingerprint Only mode must be used in conjunction with the GV-ASManager software and the GV-GF1911 / 1921 / 1922 / 1922 V2 reader to enroll fingerprints. You first enroll fingerprint data in GV-ASManager before uploading it to the fingerprint readers installed on GeoVision access controllers. To get access, the user's fingerprint must match the registered 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.

3.1.1 Enrolling Fingerprints Locally

To connect the reader to GV-ASManager:

• GV-GF1911: RS-485 or USB Connection with GV-ASManager

Connect GV-GF1911 to the GV-ASManager server via RS-485 or USB connection. To establish a connection, a RS-485 to RS-232 converter, such as GV-COM, GV-Hub, GV-NET/IO Card, or the USB cable in PC Service Package (optional accessory), is required.
