CCD Explosion-Proof Camera refers to the sensor using CCD, and the CCD sensor transmits the charge data of each pixel in each row to the next pixel in turn, from the bottom part, and then through the edge of the sensor. The amplified output is made, so the CCD Explosion-Proof Camera ensures that the data is not distorted when transmitted, so the data of each pixel can be aggregated to the edge for amplification.
