The difference between CCD and AHD cameras 1. These two cameras are used on different screens. CCD is a high-definition camera, which can be used in the general Android navigation and the original DVD navigation screen, but AHD is used on the current IPS screen, and the definition is good. If the AHD is loaded on the ordinary screen, it cannot be use. 2. The biggest difference between the Ahd camera and the ccd camera is the difference in image clarity between them. Because the signal output method used by the AHD camera is digital signal, the loss of the image in the process of image transmission will be relatively small, while the CCD camera uses analog signal output, so in the process of image transmission compared to For AHD, the distortion of the image will be higher. 3. In addition, the AHD camera has some other advantages, such as its relatively low price. The price of most AHD cameras is similar to that of ordinary analog cameras, but the image quality is much higher. At the same time, it has no delay when transmitting images, because its data will not be encoded and then compressed before transmitting, so many procedures are omitted, so the pictures transmitted by ahd are real-time.
