Selecting the right cameras for your video surveillance system is critical to the success of your system. First, you need to determine what you want the camera to capture for you. Here are some things to consider: Do you want to see a scene and know if something is happening? Do you want to see an event and determine exactly what is happening? Do you want to see the individual and determine exactly who is involved? Your answers to these questions will begin to affect the type of cameras you need.
