just to understand; if the minimum illumination is low, it means that the camera can handle better at night time (avoiding other camera's parameters)? - if this correct, then 0.001 is better (in that sense) than 0.002?That's a CVI, composite video information, camera in the "Lite" series. Look at the minimum illumination spec of .001 LUX. A 5442, 4MP camera and a PoE camera, has a minimum LUX rating of .002. The spec saying 5MP for the sensor says nothing about how big it is.
