The size and quality of your video are determined by the camera’s lines of resolution. Television lines (TVL and LENS) are typically used to reference to analog video quality while pixels are used to refer to digital resolution (IP Cameras). TVL specifies the amount of vertical lines (= Horizontal Resolution) that are able to be seen. The standard National Television System Committee (NTSC) analog video is made up of 480 interlaced horizontal lines. Theoretically horizontal resolution can be increased infinitely but hardware restrictions such as the maximum count of pixels on a chip restrict this.
