Direct access by scanning the QR-Code
The Foscam “Plug-n-Play” cameras can be used almost immediately on a smartphone or tablet by simply scanning the QR code on the camera with the Foscam App.

Someone with little IT experience can install the camera and can approach the camera from anywhere, even from the Internet.
