They will try to make money however they can whether it be through traffic cameras or parking meters that charge 8 dollars an hour in the city.

You want to deter criminals before they get onto your property.2 - Post signage about video surveillance.

I have also only had one problem with noise and my neighbors were quick to let me know.I use an exterior camera system that I can tell if there is more people than what is allowed.I imagine there may be a wifi enabled sound meter/device that can alert you if sound is over a certain dB level, but have never had the need to look into this.I also get a copy of the renters drivers license so I know who I am renting to.I also have a minimum age requirement that helps weed out a younger group that might be more inclined to be single and throwing noisy parties.

A sewer camera inspection would have probably discovered the problem. 

There were tiles handing from the ceiling, and security cameras hanging off of them.

If you are wanting to track progress or have a way to communicate about a potential property to an out of area investor, the Ricoh Theta series of cameras will take a spherical panorama of a room.  

I liked the reverse concept because it's easier should someone want to BBQ on the rooftop deck or hang out.As for the Quad/go pro, we measured off line and marked it so that we knew at what height the camera was taking pics.

You'd have to pin that to those on the political right my friend; progressives don't approve of a corporate take-over of the government, the Supreme Court defending such policies as Citizens United, the surveillance state, torturing or drone-killing, or the failure to separate church and state.

I use Homeaway.com to advertise, take payments, manage my calendar ect.I also have an AirBNB account but it doesn't produce many vacation rentals.I have a great housekeeper that I text to schedule my cleaning.I use a Lockbox for keys.I have 2 Honeywell 9000 series thermostats to adjust temp when no one is there.I also just recently installed a camera system so I can see who arrives and make sure no one is breaking in when vacant.Very easy to manage remotely once everything is going.

I'd recommend and put up security cameras and change locks and get insurance now.That sounds super scary.
