One alternative idea I've had is to actually use a wifi video camera that records the meters -- however that is not the most streamlined approach.So is anyone using connected water submeters and how have they worked for you?

One of the camera batteries was dying so I didn’t want to drain it completely by repeatedly checking the rings.

I ended up buying a professional snake (one of those thousand dollar+ jobs) from a retiring plumber for $400 that I talked down to $200.I did used to pay for professional servicing, in fact had jetting/cutting/camera done just 6 months prior to this incident which I now think half of the job wasn't even done at all let alone correctly.

They also have hybrid class online and as I understand it, you have to log in and be on camera at specific times.I'm guessing in person or live classes are proably about $1000 for the basic license...and maybe another $200-$300 over the next couple of years to take your additional SAE.Our brokerage KW also has a free online course, self paced all on your own if you are good at reading the material and then taking the quizes all on your own. 

Would you recommend installing a camera in attempt to catch and prosecute whoever is taking the money if someone is in fact doing this?

Stand right next to the guy as the camera shows the pipes - that way you can see with your own two eyes what he is actually seeing.

I'm primarily looking for a cost effective solution for potential cost segregation on a property bought about 3 months ago to see potential savings for all the dirt work/gravel/fence/gate/cameras.

The house is SMALL and the neighbors have cameras.

Also bad was the nanny's bathroom. 

It syncs with payment processors, and other vendor software (gates, kiosks, cameras, etc.).
