Analog resolutions are usually referred to in TVL (TV Lines). 420 TVL, 480 TVL, 540 TVL, 600 TVL, 700 TVL, 1000 TVL - What are TV-Lines really? It is easier to see the difference between analog and mega-pixel using a picture showing the same scene at different resolutions.
The QVGA image is 1,228,800 megapixels just less than the 1.3mp or 720P. By comparison a 700TVL camera has about 480,000 pixels.
The 1.3mp is 3X the quality of a 700TVL camera and the 2mp is about 5X the resolution.
These resolutions give a wider viewing area and allow greater distortion free digital zoom.

High-Write Workloads While PC data workloads require storage biased for read capability and small-block, random data transfers, video storage must be engineered for writing and large, sequential data blocks.
