Low cost dependable webcam - PC video recording

Looking for off the shelf system or parts to build a laptop based usb
web cam slow scan to HOD and / or DVD-RW, 2-15 frames per second and 1
or more weeks of time dated images. Would also like, as a plus, to store
periodic GPS data and other data with the image data. Medium image
resolution range.

OK, VIDEO BLACK BOX for com./ mil. vehicles. Vehicle data + GPS + images
through the windshied and maybe both sides to the rear.

Thanks

Dennis
