The Face-out* utility in CyberLink YouCam can auto protect your computer when your face exits the webcam image, by locking it, or by making it hibernate or sleep.
To set up and enable Face-out, do this:
Note: if you previously enabled Face Login, CyberLink YouCam will use the same image. Select the Show all faces link if you want to view and remove any of the captured images of your face.
Note: to disable Face-out, just reenter Face-out settings and then deselect Enable Face-out when I am not in front of the PC item.
For further detail instructions, please refer to YouCam user’s guide.
