What are the differences between CCD and AHD reversing cameras?
1 Answers
The differences between CCD and AHD reversing cameras mainly lie in five aspects: design, video resolution, noise level, sensitivity, and power consumption. The specific differences are as follows: Design differences: In terms of design, CCD cameras use a single photosensor, while AHD cameras use a photosensor connected to an amplifier. Video resolution differences: CCD cameras have lower connection complexity and higher resolution, whereas AHD cameras have lower resolution. Noise level differences: CCD cameras have an advantage in single amplification, allowing noise to be minimized. However, AHD cameras show significant noise after amplification, which is relatively more pronounced. Sensitivity differences: CCD cameras vary in sensitivity depending on the machine standard under the same area. Compared to AHD, AHD cameras have smaller light-sensitive apertures and lower sensitivity. Power consumption differences: CCD cameras require additional voltage, resulting in higher power consumption. In contrast, AHD cameras directly amplify the signal, leading to lower power consumption. Generally, reversing radars and reversing cameras in cars are interactive. Currently, all cars are equipped with reversing radars, but only some low-end models lack this feature. A reversing radar is an audio-sensing device that helps determine the distance between the car and obstacles through sound or virtual images, working in conjunction with the reversing camera to avoid scratches during reversing. Some cars come with built-in reversing cameras, while others require aftermarket installation. For novice drivers, this is a highly practical device. Reversing cameras provide drivers with sufficient visibility, allowing them to accurately judge the distance between the car and obstacles with the help of the camera and rearview mirrors. During reversing, the camera offers a more intuitive view of the rear situation, making it one of the most practical safety features for reversing, ensuring accurate distance control.
