Patricia, I have installed outdoor security cameras but still have had 3rd party bookings and in fact just got suspended because the 3rd party person stated the property didn't look like the photo, rules were too excessive, didn't like location. I asked Airbnb how I could be suspended on reviews from people who are not registered with Airbnb and the person who is registered with Airbnb did not show up on my security cameras as the person staying in my unit? I'm really hot about this so I'm searching for what other hosts are doing about these 3rd party bookings. I have called Airbnb in the past and notified them of such and they called me back and asked if the guest could stay? What? I've been a host since 2015 with two units and the guests have continued to want more for less money, but are critical of what they choose to book. Parents are using their names, but putting their child's photo on the account. When I called to verify who was going in and out of my unit because that person did not look like the profile photo, the mother just kept saying, "she's a good girl". Her profile is still this way.
