Computer people? Webcam question.

On my next grow I would like to set up a webcam attatched to my old laptop in my grow room and i would like it to take a picture every hour during the veg phase (when lights are 24/0) then once and hour for the 12 hours of light during flowering. Anyone know of a webcam program that can do this? I need it to be mostly automated cause I'm not gonna be around every hour to take a picture. duh.
Thanks guys!

If you are using a Mac:
Apple - Downloads - Video - Periscope

(and many others)

For PC, you can start here:
Security Video Camera Surveillance Software - CrazyPixels

(again, many others)
just google webcam control or something like that.
