Megapixel : 1,000,000 pixels and also the measure of the amount of display elements in digital display or camera. Megapixel and multi-megapixel security cameras capture video footage at a significantly higher resolution than their analog counterparts, i.e. a 1.3 megapixel IP camera captures 1,300,000 pixels in a single frame (1280×1024), 2 megapixel captures 2,000,000 pixels in a single frame (1920×1080) etc.
