Video stream from Android phone to laptop over the internet
I guess there is: WebCam Free consists of an app for your Android device, plus a server component to be put on your computer. From the apps description, this could do what you want (didn't try it myself, but it's certainly worth a look). I linked the free version; a paid version is available for about 1.50 Euro.

If that doesn't do (or you don't like the idea of a PC component), you might give a try to Cloud Spy Cam (it also has a demo available on the play store). Sounds even more promising (I'd say this is exactly what you're looking for).

But since all good things are three, a third option is IP Webcam, which "Turns your phone into a network camera with multiple viewing options."

So now, happy play!
