These guys are predicting a $1 Billion market for DIY network cameras by 2012. That works out to about 10 million cameras per year, if you assume the cameras cost about $100 each.
Gosh, sure would be nice if someone built a cloud based service that would leverage all those cameras. Wait, that's what sensr.net is about.
