They're looking at Zillow on their cell phones). 

If the wall of a home or building constitutes part of the pool enclosure, the above fencing requirements may be substituted with one of the following:A wall, fence, or barrier that is at least four feet high; A motorized safety pool cover that requires a key switch, which must meet standards published by the American Society for Testing and Materials;A self-latching device on any doors with direct access to the pool area.

So, over the past year I’ve been using a proprietary software that allows me to collect data of commercial property owner: Name, cell and home phone number, email address, home address.

Adjust the cells for your area of course.I’d be glad to email or give the link - lmk Good luck and have fun!

Cell phone service coverage, etc. 

I've been looking into companies like True Submeter and Metron meter for water which were mentioned on BP previously but they seem to be just meters connected on each device that measure all the water usage so thinking that could be an easier alternative? 

I'm needing cameras and video to my cell phone and my property manager's cell phone.   

Did you simply tell the tenants that you'd like to connect a few devices to their WiFi router? 

I went the submeter route and am very happy with True Submeter, they send you the kit to have installed by plumber. https://truesubmeter.com/Then they monitor usage via the cell network and send you the bill (or your PM) to then bill the tenant.

Just put a family member or yourself for the landlord and put your cell on there.
