A particular demand from some of the cities is that airBNB should collect certain types of information at the time of the booking, rental address, name of renter etc.. and transmit this information or make it available to the cities somehow, so the cities can utilize for checking against a database or registry of some sort to better monitor compliance etc... 

Nowadays you can even get them that transmit the data through WiFi so you don't have to physically read them.

I've worked for Barnes and Noble, Hearst, NBC/Universal, USA Networks, and Random House and have freelanced for many other bold-faced companies.I'd love to trade my skills, experience, contacts, creativity, and eagerness for a chance to mentor/partner with an experienced S/MFH investor.Though I eventually plan to move out of the area (not for at least a year), I will always have connections here and many friends.

If the cameras are going to alert them every time someone is coming over and they are going to bother you about who is there and why, I would suggest looking into more traditional cameras that are recording/transmitting without sending alerts.

It may be a little messy the way it transmitted through.

For instance say there was a DB for people with a transmitted disease.
