All-in-one camera refers to an all-in-one camera with built-in lens and auto focus. There are many types of integrated cameras, and the current market players can be divided into color high-resolution type and day-night conversion type, with the maximum magnification of 16, 18, 20, 22, and 27 times. In general, the trend of the all-in-one is that the illumination is getting lower and lower, and the multiple is getting higher and higher.
