A few commenters pointed out that the guest was in the wrong, for having a pet over, not the renter for having security cameras. The first thing to point out is these are not mutually exclusive, I think both parties have broken some moral boundaries. More importantly though, if we accept that this guest´s bad behaviour justifies the use of a camera to detect it, does it also justify the owner (presumably) spying on every guest? Even those who don´t break any rule at all? Do we consider that okay - the ends justify the means, the owner has the right to monitor for house rule violations? If so, where´s the difference between this and being spied on by Facebook or other communication platform? You rent your "online presence" from them, pay them by having ads shown, a contract like any other. Why then shouldn´t they spy on you to monitor for breaking any arbitrary rules?
