Can anyone share or recommend a fairly boiler plate disclaimer / advisement to include in our "guest book" and also check-in instructions for the STRs that we own? 

Context: I am also a Realtor in CO and for us it's become important to disclose to would-be-buyers touring our seller listings when there is audio and video recording equipment in use. It's occurred to me that it's probably not a bad idea to include this in our check-in instructions and guest book for our own protection. After all, there is a impact on guest privacy.

Note: we do not actively monitor guests / activity. However, it's important to have cameras for a few reasons, to verify check-ins, security when vacant, evidence in the event of an incident, violations of pet policy, etc.
