Though there are lots of tools- plumbing digital cameras to see inside of everything for example; however, I don't see machines doing stick built houses in a myriad of a million situations, yet.

Mine are in a third world country so for $4/hr they’ll set door codes, message (or call) guests, schedule cleaners, adjust the thermostat, monitor my cameras, call a plumber, etc.I too often spend around $99/mon per property but I can’t imagine you’d get the same level of quality & service that I do for that $99/mon price domestically

And then there were cameras. 

Keep a camera handy to take pictures of problems as they come up during the reno to post here.

The police even took the SD card out of my Harbor Freight camera set up to cover their actions crazy right?

She sent me RING camera footage, and I can see over 15 people running back into the house after a MASSIVE fireworks explosion goes off at ground level.

I am now looking for an outdoor security camera that doesn't require wi fi. 

You don't need security cameras to monitor them.

Steel doors and frames; Gated perimeter and main entry access with high security keys that cannot be copied (not just stamped "do not copy") or an access control system that uses rfid proximity readers, with remote access; excellent dusk to dawn lighting with poly-carbonate and/or protective screens outside; timed led interior lighting common areas; a quality, well featured and easy to use remote access security camera system; card operated laundry equipment in well lighted, space with folding tables and vending machine(s); establish "House Rules" for all with a stepped schedule for fines, use the camera system and access system to identify violators (including those dumping trash in the alley) and assess fines (or report to PD) promptly and consistently; do not hesitate to get rid of any troublesome tenants...DO hesitate to accept questionable prospects.

I would appreciate any recommendations from those of you who use cameras for security purposes.
