The batteries last about 6 months in each camera before recharging (aka no wiring either). 

You might find the property you buy is landlocked and your first job as the new owner is getting legal access.As for access to the interior of the house, if you have a battery powered drill you can get access. 

It would be better to see if it is possible to legally rent out a part of your home to your LLC and charge rent.  

@Zachary DealIn the Tahoe Reno, NV market we are seeing more interest in MTR because of the influx of tech and manufacturing jobs with Tesla building the Semi-truck factory, Panasonic building batteries, and Redwood Battery recycling the batteries.

Guardian EV is a truck yard that has installed chargers, we'd be open to installing them on our yards, but not without a 100% subsidy

Batteries in those units last much longer than WiFi due to the wattage of the radio.

If you are in a heavy sun, high cost of electricity and high rate of usage market, and you buy the panels, and you can resell to the provider rather than maintain your own batteries, you probably will make money especially if you hold long enough.

We both got in trouble for simple battery.

I think this technology will continue to improve over time giving more battery power and additional capabilities.Even the less expensive brands have worked well in our communities, I guess we will see how they compare over the next few years.

Batteries last for years and I've never had one fail.
