I just received and installed in my home. It was rather simple to hook up. I am not sure if it will work on the second floor as I couldn't set it up on my second floor but was able to when I was a few feet from my router. So as of right now I'm a little concerned if the 2nd camera will work when it's further away then my first camera which is within 50 feet of the router. I do have a call into tech support to ask some questions but it seems they prefer emails then returning phone calls
