Remote property access and cameras for self-guided tours?

[Madelyn Felix]

Are any property managers (with 20+ doors) controlling access for all of their properties under management remotely with smart locks-in one system?

  Does anyone have a recommendation for a service for property managers that integrates the use of motion activated cameras to monitor self showings or vacant properties?

It seems like the cost of smart locks, WIFI, cameras and installation would be about $600.  Who is offering a solution, or is there one? 

Trying to figure out how to minimize the upfront costs for each door.  

Any help, input or advice is appreciated!!
