i believe the device can be used within the US, as long as there is someone who can install it.SO, my question is? For anyone that are more familiar with this device, since the website didn't help much. Is this device only available and viewed within California - Minnesota area or is anyone from any state able to order this device and watch it from where ever they're from? Because at first, I thought, well, if I order it and I'm from North Carolina, I can watch it. But then, someone said something about having an installer come and install it for you...who are the installers?
