Before you actually invest in a security camera system, you need to think about what you'll be watching and what you need in order to watch it. The number of cameras you want is probably the first question that should come to mind. Are you focusing on one room in the house, or do you need to keep an eye on several different parts of the house? Will you need to monitor outdoor activity as well as indoor? If you're simply watching over one room, you'll probably need just one camera, but including more areas requires a bigger camera system.
