Battery powered WiFi cam, it can't be this exotic
 

I have been trolling google and amazon for a Wifi Cam that can stream to the Internet and be accessible via DDNS and is battery powered.

The only product that seems to does this is the Vuezone, but they want you to subscribe to them for smartphone stream!

Amazon.com: VueZone System with 2 Indoor Motion Detection Cameras (SM2700): Camera & Photo

Is there some sort of 5V 1 to 2A DC jack battery pack that can act as the power source instead of the included power cord?

All I want is a battery powered Wifi cam capable of streaming via DDNS, it can't be this exotic of a requirement.

Anyone?

I just got a Foscam unit.
Not battery powered but pretty cool.

Looked at that one too, seems nice. But for crying out loud, how difficult would it be to have some kind of provision for cordless power source.

I don't want to depend my stream on some subscription, which is why I have not bought the Vue unit. I realize that I might have to because there doesn't seem to be any alternative.
