Home Surveillance Guest Etiquette

You have quite a lot of cameras on your property recording things. Nothing invasive or intentionally meant to spy upon people like bathroom/guest bedroom cameras but more just general security.

Driveway, dock, garage, entrances, yard, etc.

What obligation, if any, do you have to disclose to your guests.

Let's say you're throwing a bbq in your yard and the entire thing will be captured on security footage.

Babysitter

Dog walker

Gardener

etc

do you disclose, should you disclose, how do you disclose?
