TVL Resolution

Resolution is one of the most confusing topics in the world of CCTV. The majority of people have a digital camera or a video camcorder. Almost everyone has probably heard the term megapixel as the common type of resolution comparison between the various makes and models. The larger the number is the better the picture quality is going to be, but a lot of people do not understand why that is exactly. Most of the cameras are still run on analog and the resolution is actually measured different than what everyone is used to, in the world of CCTV security cameras. Even though this is slowly changing, there is still going to be that need for people to understand what exactly the terms and technologies mean.
