Looks good on paper but have not tried it but seems pricey at $75 each (you need 2).
What I use is the Trendnet kit, comes with two Powerline adapters and they have outlets on the front, costs about $70. Then I use a wall plug injector, plug it on the back of the Powerline adapter and attach with a short 1' cable. Not saying the other one is not better, just haven't tried it. What was nice with my setup is I ended up putting two cameras there, so I was able to replace the PoE injector with a PoE switch which I can't do if the PoE is built into the Powerline adapter..
