It might be worth it just to learn what you really need and want. Just like you can't recognize someone from a convenience store security camera, your IP cameras won't be any better unless they're HD. Ideally, you'd have 720p or 1080p video cameras as well as still cameras capturing at a high megapixel resolution, both interior and exterior.
