7. Smart Locks
Another nice accessory to have at your front door (and all doors) is a smart lock. Now, it might seem excessive to want to unlock your door from your smartphone when it is so easy to do it by hand. But the benefit is that you can unlock the door from anywhere. That can come in handy when the cable guy finally showed up but you had to run down the street for milk.
Smart locks also have other handy features. You can set individual codes for different people so as to track their comings and goings. Some smart locks even allow you to program windows of time where a particular code will work. Even cooler, some kinds allow you to set up a perimeter around your house. Once you leave the perimeter area, the door automatically locks.
