CMOS Explosion-Proof Camera refers to the CMOS sensor, each pixel will be adjacent to an amplifier and A / D conversion circuit, the data is output in a similar memory circuit, so the data of the CMOS process will be generated when the transmission distance is long. Noise, therefore, it is necessary to first amplify and integrate the data of each pixel, but since each pixel of the CMOS sensor is composed of four transistors and one photodiode, the photosensitive area of each pixel is much smaller than the surface area of the pixel itself. Therefore, in the case of the same pixel size, the sensitivity of the CMOS sensor is lower than that of the CCD sensor, but the cost of the CMOS is lower due to the process gap.
