These are 3 tools that I use to Co-Host 100% remotely 1) Smartlock - Schlage or Yale- This allows me to virtually add codes for each guest reservation and unlock/lock the door as needed2) Security Camera - Ring doorbell - This allows you to see who is actually coming into the property and confirm it is the person who booked the property.

a) A buyer must always get a sewer camera inspection.

I don't like it and will eventually find someone who likes the camera more than me, but our logo/name is on point and neutral. 

Sometimes knowing why but for silly reasons (a guest complained about a camera that was properly disclosed in the listing, etc).This is also why I don't use the same AirBNB account for my own travels as I do for my hosting. 

Security cameras imply you are providing safety.  

Wireless Cameras for vacant properties.

What surveillance system have you worked with and do you recommend. to be budget-friendly and effective (Ideally, I like to lower insurance payments by adding a surveillance system to the property)

Added security cameras and lights rented garage What was the outcome?

Bring: three spare bolt lock sets, crowbar, tool kit, cell phone fully charged, camera, lots of cardboard boxes and used bubble wrap that you glean from some furniture store that throws those out, pickup truck, gloves, apron, masks, and febreeze. 

Security cameras inside.
