If you're super paranoid, you watch the camera and count people.

As we know the type of person she is, we put cameras on the driveway to have proof that this other person was living with her. 

The property must have been under some kind of surveillance. 

Use 360 camera.

We’ve practice this with several other of our multi family clients and found that the most important factor in the rehab that enabled us to up the rents was to install wrought iron fencing, security cameras, new parking lot and key card access.

Also keep in mind I would be fully insured up to $10 Million in Property Damage and also FAA Certified to fly drones for commercial use.​It includes:5 Drone Videos at 4 Different Locations/Properties per monthEach Drone video is 1-2 Minutes of Edited Drone Footage in 4K and also features copyright free audio5 VR Tours/Month of the same location captured by 360 Degree Cameras with embedables to place on your site​So, assuming real estate agents like yourself were to see my demo reel (and see how great the footage is) my questions are these...For $2,500/month is this really a bargain for you Real Estate Firms?

But I keep a camera watching the door from the inside. 

If you can get into the sewer line with a camera.....bonus.  

Mine can set door codes, message (or call) guests, schedule cleaners, adjust the thermostat, monitor my cameras, & call a plumber just as easily as a local PM can, for 1% of the costI wrote much more about leveraging offshore assistants in this post here.

If you don't already have cameras and/or an alarm, that may be a worthwhile investment.
