I don't think Blink is quite the same, as they have their own IC, whereas I'm pretty sure Netgear is using something "off the shelf" and just tuned it to be mostly off.
Blink seems to have designed their hardware from the ground up to be low power, whereas this simply turns everything off until there's a motion. This also means that the Netgear hardware will run out of power really quick if there's a lot of things going on.
I'm not trying to knock them and the ease of placement/installation is great, but I don't believe current technology is quite there as yet for something like this.
