I'll not go into details of what I have in my own home, nor of those I designed and built for clients, but with anything "security" you are better with multiple layers as opposed to one device to defeat. How you stack those layers is based on budget and use.
A door that looks like a normal door, but is not, is generally a good first step. Make sure to get hinges, jambs and hardware that can not be defeated with a few swings of a 5 pound sledge and you are off to a great start. A motion detector on both sides of that door is a good second step.
