“Camera resolution is one of the most important specifications to consider when purchasing a security camera or video security system. The right camera resolution can be the difference between identifying and apprehending a criminal or letting them walk away with justice having not been served.
The resolution of a security camera is indicated by the number of horizontal TV lines that make up a picture. Each individual horizontal TV line is made of a number of pixels and the total number of these lines makes up the full picture you see on your screen. The more lines of resolution per picture, the clearer the overall picture will be.
Security camera resolution is not the only factor that determines the resolution you will get as the end result. When choosing a video security system for your home or business, consider the resolution of each individual component comprising your system so you can select devices with similar resolution, and attain the highest picture quality as a result.”
