The sensitivity of a CMOS sensor is usually 10 times lower than that of a CCD sensor. The human eye can see the Targets below 1 lux illumination (night of the full moon). The CCD sensor can usually see the Targets below 0.1 ~ The target with less than 3 lux illumination is 3 to 10 times the sensitivity of the CMOS sensor.The sensitivity of the CMOS sensor is generally within the range of 6 to 15 lux. The CMOS sensor has a fixed noise 10 times higher than that of the CCD sensor, fixed pattern noi
