I was reading some of the reviews, and I dont understand why people say that you have to pay to use it. The free version works just fine for me on my "local" network. I think you have to purchase the full version to use on "external networks" like when you leave the house. But for the price,the results are more than expected and awesome! I have my laptop setup right now as an impromptu babycam. Yes there is a lag, but its not a big deal, im not trying to have a conversation with anyone. The picture is color, and the audio works. This product makes me love my iphone and my mac even more!
