Well this sounds very creepy, but imagine for a moment that the landlord might only be checking if there's child pornography going on at his house, then I guess it would be ok. Also he pinky sweared not to share those images with anyone else. Now imagine the landlord is not a person but instead a fluffy cloud...
The instructions for getting settled in the house were first how to disable the electric fence then how to unplug the surveillance system during the stay, and obviously how to reenable them all on checkout.
This is how it should be done.
