The G2-4G is access control for the world we live in today. Powered by mobile technology, it offers handsfree, touchless and even automated access control complete with remote user management. The G2-4G is a GSM access control powerhouse offering access control for any secure entry/exit application. The G2-4G can be used with existing access panels so incoming phone numbers' Caller ID are passed to the access panel as a ‘virtual card no.’.

As a standalone access control unit, no additional parts are required if Caller ID is the only required method of access. The controller supports a complete range of access control options by simply connecting the chosen components to the controller.

The G2-4G supports a range of optional add-on components to create the access control functionality required.
