I have been looking into wireless home security camera systems and am not really getting anywhere. What I am looking for are 100% wireless systems. I want WIFI battery powered cameras. Where I am wanting to put them would be a real chore to run power cables. I can find the wifi systems all over the place but am having a hard time finding the battery powered ones. Anyone out there have this type of system, and if so what brand are you using and how do you like it? Any help would be appreciated.
