How many mega pixels is analog 800tvl?

Analog cameras with 800 TVL (TV lines) typically do not have a direct megapixel equivalent, as they use different methods of measuring resolution. However, 800 TVL is roughly comparable to a resolution of about 0.4 to 0.5 megapixels, which corresponds to a resolution of 640x480 pixels. Therefore, while not directly comparable, 800 TVL can be understood in the context of lower-resolution digital cameras.
