Little or no typing is required to operate the system. Our product works with touchscreens as well as with a mouse and keyboard. Just tap on an icon representing a residence unit and all the information about that unit will instantly appear on the screen. Tap a name on the preauthorized visitors list and the guest is instantly logged in with the date and time automatically inserted. The system is specifically designed for intuitive operation, so training time for all users is minimal — about 5 minutes.
