GV-CR420 is a perfect convergence of intelligent video surveillance and access control. It is a card reader built-in with a 4-megapixel wide angle IP camera, giving a clear wide angle space imaging at point of entrance, thus extending the field of view for more background information. With the built-in face detection function, the camera reader captures only accurate face images, filtering those faces hidden by masks or helmets!
Reader with camera built-in
Advantage of the built-in camera, aside from easy installation, is that it is ensured to capture the face of front view. As seen in following comparison, when camera is not built-in within reader (and normally camera is installed away from the reader shooting from a higher point), it is difficult to get a front view face shot. Face images can be even more accurately captured if face detection mode is enabled.
When camera is not built-in with reader. The face can be more blur if not using IP camera (vs. GV-CR420 is built-in with a 4-megapixel)

Wide angle camera, more background information
GV-CR420 uses wide angle lens, providing extra space imaging in compare to traditional camera. The advantage of this is that it catches full face images disregard of their heights. It is also possible to include images more than just the card user, for example, tailgaters may also be included in the camera view.
Without the wide angle function, it is difficult to determine a position to catch face images from all heights.
With GV-CR420, face images can be captured at human heights including background views, thanks to the wide angle function.
Fully integrated with video surveillance
GV-CR420 captures and transmits live view to GV-ASManager, GeoVision’s access control management solution, and GV-System, company’s surveillance video management solution, through network connection.
Advanced authentication mode – Card and face detection mode
GV-CR420 enhances security through the special authentication mode – card and face detection mode. The mode grants access only when the card and a face are both presented. This is to ensure face images are correctly captured as intended at entrance, for retrieval as needed later. Face detection mode may be enabled by schedule to increase overall security at times needed.
