Reduced cost: The platform based development model reduces the cost of development of camera products considerably. Nowadays offshore companies can even lower the cost of development especially if they are developed from scratch.
Application Support: Support at the application level is crucial especially in context with image processing algorithm development. Years of expertise and experience in imaging and image processing boil down to the efficiency rendered during support. Also a company with resources who have previous system integration experience would relate with customer needs and pain points too.
