The purpose of this work is to show, how to build surveillance system with the web-page interface. The webcam can be turned in the vertical or horizontal direction throught the interface, but only in the area that border sensors will allow. The control page is secured with login system, where the user types in an username and a password.
On the control page the user can control how the webcam will turn and how many steps it will run. The user can also turn the webcam on and off via web interface. Information about the states will immediately update to screen. User can also turn the motion detector online, if the camera detectd motion, it will automatically save the frames. Naming of the pictures is done with "timestamps", so it is possible to find out when the picture was taken.
The camera interface is coded by using PHP and XHTML programming languages. The micro controller is programmed by using C-language. System works on Linux operating system.
