If you do go, I would look at smartthings. They do not have a FREE camera option however, they have linked up with dropcam which requires a fee for video storage.
I am seriously considering them for a vacation home. I am going to stick with Vera since I have it working now and it is meshed with my Concord 4 panel.
I have spent hours on the smartthings forums trying to determine if their product is more “finished.” My initial opinion is for basic functionality it appears to work better out of the box.
I still may go with vera for the vacation home since I am going total z-wave…but smartthings is giving me pause. Also, smartthings can work with both zwave and zigbee.
