2023 Update AHD Digital Wireless Backup DVR Record Camera 4CH Kit with 9 Inch AHD Monitor for Truck/Trailer/Bus/Pickups/Trailer - Clear Images

This kit uses AHD technology to deliver dependable, ultra-long-distance HD video transmission over analog lines (up to 500 m). It employs advanced Y/C signal separation and analog filtering to substantially cut color noise in the high-frequency band and reduce image degradation. Compared with traditional CVI signals, AHD provides a noticeable jump in surveillance image quality and supports resolution on par with HD 1080P. The AHD-M(TVL) format adds clearer, brighter color separation, enhanced signal filtering and 3D noise reduction technology for improved clarity and more accurate image reproduction. Built around a highly integrated AHD front-end chip, this solution offers high-definition performance while allowing coaxial transmission on ordinary 75-3 line distances up to 500 meters.
