Rental guard
We have heard of security you can rent for events and other gatherings or places, but we didn’t know this was a thing. Apparently, you can just rent a doll and place it somewhere to fool people into thinking you have heavy security. We’re not sure if this is actually effective, we’ve never tried it before.
We think that anyone who is committed to stealing something would figure out fairly quickly that this house’s entire security system is a farce. The sunglasses and video cameras were a nice touch though, it would probably trick anyone who didn’t care to look closely. Maybe they named the guards as well just to add to the realism.
