Although I kinda knew going into it that I would not rely on the iPads video camera, people can get caught up with the shiny bright advertising game that kind of leads you to believe that that this iPad with this I sight camera will kick butt!
Plus when you read below (from the Apple store) maybe the OP might have thought otherwise.
Just my 2 cents.
Megapixels matter. But the quality of a photo is determined by other things, too — like the camera’s optics, image signal processor, and software. The iSight camera uses advanced optics to give you the best picture possible. With an ƒ/2.4 aperture and a five-element lens, it captures light efficiently to produce a sharper overall image. And the hybrid infrared filter — typically reserved for expensive SLR cameras — keeps out harmful IR light for more accurate, uniform colors.
