Ok, I have an had an idear. What I want to do is buy a web cam, now here is the kicker, do some web cams come with motion activatiation? (i.e.) When the camera senses motion it starts recording, when it stops senses motion it stops recording. Does anyone know if they do that?

If not, is it possible to write a vb program to do so, I guess the prog could take a picture every second and compare with the one before, if it is different then have the cam start recording, and record for a specified amount of time and/or the pictures start being the same. Anyone think this is feasible to do?
