Often the most confusing and difficult parts of shopping and choosing out a proper CCTV system is the resolution. We all hear about different amounts of TVL, if it is 450, 540, 600, and sometimes with Megapixel and digital CCTV, but we do not know what it is. And of course we know that a higher number can mean a better quality in recoding and with the pictures, but how does this work? When it comes to CCTV cameras and systems, we mostly use analog cameras, and with those systems, we use TVL, which means television lines.
Q: I like your explanation of this information. When is it best to use a megapixel camera over analog type? Is outdoor use ok for megapixel too?
A: Megapixel and better resolution IP cameras capture more detail in a given image than their analog cousins.
Q: Would an analog camera with 480TVL be similar to 640×480 resolution?
A: The short answer to your question is yes, but I will give you the more technical answer below.
