The Smartphone (with Windows Mobile 6 OS) can run as web server with capture ability and send the picture to the client via internet. Other features of this circuit is the Smartphone can also moved and controlling motors with his speaker, emitting the correct dial tones in relation to GET requests from internet client. It's not necessary to make any connection from the phone to the circuit, because the phone connects "wireless" using the sound.
