I think it would be pretty nice to have com systems setup in front of your house. This one looks like it also has a door lock to it which would be perfect for a gate or front door. I want to get something like this for my gate to make my house a little more safe than it was before.
I love this website, they have lots of old looking hardware for doors that actually works like the originals. For example the door locks come with a skeleton key that locks the door from both sides. So cool!!!
