We have stayed in quite a few cottages over the years and have never had security cameras on them. We are currently staying in a decent cottage hired directly from the owner and it has new security cameras on the front door and the back door and overlooking the back garden (which has an outdoor hot tub in it).
I noticed when we arrived the camera over the front door rotated to view us when we came in which I guess could be a sensor rather than a remote mechanism.
I just can't decide how I feel about this, I think I feel quite creepy especially about the camera overlooking the back garden. The owner lives nearby so could check on the property easily.
What would you think about this?
