Question: Can we use a digital camera as a web cam? 

Answer: Some cameras do support this, but it's not a very common feature.  The only one that had decent features that I was able to find without too much trouble was the Creative Labs PC-880.\nhttp://us.creative.com/products/product.asp?category=218&subcategory=221&product=308\n\nIf you already have one and want to know if it has that functionality, it would be very helpful if you could tell us the model and we can help you research it.
