All-in-One Solution

GV-CR420 is a card reader with a built-in 4 MP wide angle IP camera. The card reader recognizes identification cards and grants access accordingly. The wide angle camera captures all angles of the entrance and transmits live view to GV-ASManager and GV-System through network connection. The all-in-one solution eliminates the need of installing and maintaining a separate camera in addition to the card reader.

Card and Face Mode

In addition to granting access after a card is presented, the integration of card reader and wide angle camera allows you to enable the Card and Face Mode, where the camera reader needs to be able to both recognize the card and detect a face before access is granted.

Web Interface

Using a browser, you can watch live view and utilize functions such as motion detection, privacy mask and alert notifications through the Web interface.
