She said she had to think about something sad to calm herself down so the camera would accept her face. 

Smart locks and security cameras (outdoor only) add an extra layer of control.

Communicate expectations upfront—because once they start double-parking or treating the place like a frat house, it’s game over.Cameras, Cameras EverywhereYou’d think adults wouldn’t steal each other’s food, right?

I currently have cameras, but they don’t give audio.  

The sellers had put so much pots, plants, planters and shrubs out that I thought there were too many plants/planters that would require a new owner to upkeep.After a few potential buyer tours/showings, the owner heard all the comments (via the security cameras) about how there was a "lot going on with the plants and stuff out front".

Squatters break into vacant homes, can present fake leases, and are a valid problem, but if you have cameras on the house, you will be able to get them out right away and you will see them going in.

Yes, i have ring cameras etc.Excellent suggestions. 

Looking for some advice.A prior tenant did some malicious damage to my property.I called police, they attended and the report said they were wearing body worn cameras.

All for a sign as long as the property looks occupied...leave shoes near the front door, have exterior lighting, and at least a RING camera. 

I also have camera's on many of my multi-families so that helps(only on exterior)Keep pushing man!
