Has Anyone Added a Deadbolt to the Bottom of the Door?

A thief walking around with a step ladder draws attention. Most modern unit windows are well off the ground. I guess they could bring a buddy to hoist them, but then they have to split the meager profits earned from the crime. All they want is the TV, they seem to know what units they won't hit with the slides in blocking access to the TV. Outdoor kitchens with TVs are easy pickings.
