There are a lot of developers who try to integrate web cam interaction capabilities in their applications. During my work as an administrator on an online developer community, I encountered many question regarding this topic. The variety of implementations is huge – some people recommend using SDKs provided by the camera manufacturer, some advice using the WIA (Windows Image Acquisition) layer. It can work in specific situations, however, these are in no way universal solutions. From my own experience, I can say that not every camera manufacturer provides a SDK. Also, many of the new cameras (especially those integrated in laptops) aren’t WIA-compatible, so this is also not a choice.
