When you are choosing a type of home security system, you have to ask yourself a few questions. What is it that you really need? How much are you able to spend? Are you going to do the installation yourself? Different people are going to have all manner of different answers. You might need to have a large system for your massive property. You might only need a single camera, or perhaps two, to watch over your home. Choose the system that makes the most sense to you.
