@Lenore22,
Put surveillance equipment only outside. It's against Airbnb policy to have cameras inside of the listing. In addition to checking the box for cameras during the listing setup, be sure to specifically state on the listing page and house rules that there are security cameras. "For the security of our guests and the property, there are cameras located XX."
We don't provide cable service either, but the TV is connected to rooftop aerial antenna, and we connected a Roku streaming device for guests to use. It has been my experience that most guests will login with their own accounts, and we do not offer any streaming services. I prefer Roku vs. the Firestick, because there buttons on it for popular apps.
You can publicize the listing at any time, and block the dates on your calendar until you're ready to take guests. Do not turn on instant book, regardless of the suggestion from Airbnb. New hosts are targets for some of the worse types of guests. Have guests send you booking requests, and through communication find out why they are traveling, who is staying, and what they plan to do while at your place. You will also have more time to read their reviews (the ones left for them and the ones they left for hosts). If they don't have any reviews, really stress that they acknowledge reading your house rules, and ask them several times if they have any questions. Be ready to update your house rules as you go along, because something will always come up that you didn't think of.
I have have a separate website, a Google website, and a Facebook page, as well as listing my properties on other reservation platforms. They all take some work to setup, and maintain. It just depends upon how much effort and time you have to manage them all.
