1080P effective pixels AHD Technology ( Only support AHD monitor ) In the product, filled with silicone, super waterproof 4 PIN connector, easy to install DC:9V-14V Starlight Night Vision. The visible distance is 20 meters, automatic gain control, auto white balance, auto backlight compensation Starlight night vision:As long as there is light, it can intelligently fill in the light, suitable for installation inside and outside the car.(The product does not include a display, the display shown in the picture is for reference only). AHD technology can realize reliable transmission of ultra-long-distance (500 m) high-definition video signals on analog transmission lines; it adopts advanced Y/C signal separation and analog filtering technology, which can effectively reduce color noise in high frequency region and image reduction. better. Compared with the traditional CVI signal, AHD's surveillance image quality has a qualitative leap and improvement, and the resolution can be equal to the HD 1080P level. AHD-M(TVL): Clearer and advanced bright color separation, signal filtering, 3D noise reduction technology, higher image clarity and better image reproduction. transmission far from the coaxial transmission of ordinary 75-3 line up to 500 meters zero-delay front-end data is not encoded and compressed to the back end, full real-time, high fidelity Highly integrated AHD front-end chip, high-definition quality products.
