A single cylinder deadbolt lock is a lock opened with a key from outside the house or apartment. A key isn't needed on the inside - the door is locked from the inside by turning a knob.
A double cylinder deadbolt needs to be opened with a key from both the inside and outside.
So a single cylinder deadbolt is considered the safest, since you don't have to search for a key when escaping from a fire or another emergency.
However, a single cylinder lock makes it easier for a burglar. If there is a glass panel in the door or a window close by, the burglar can break the glass, and reach in and open the door by turning the knob.

It is a kind of deadbolt for an entry door in a house or commercial site. The concept is, with a standard deadbolt, you have an outside part that takes a key to unlock, and an inside part that you turn a small lever to lock (single cylinder). If you have glass near the lock, a burglar can break the glass and turn the lever and gain access. Unfortunately - if you have a key cylinder on both sides of the door (dual cylinder) you could potentially lock yourself in the house when you need to leave in an emergency (like a fire). The solution is a lock that is convertble from single cylinder to dual cylinder. A key is held "captive" in the lock until a second key releases it when you leave. This is a captive key system
