NVP2440H/2441H are newly developed chip-set to its AHD portfolio. Similar to its predecessor (NVP2430H/NVP2431H), NVP2440H/2441H can work with progressive scan CMOS image sensor to delivery up to 2.0 megapixel (1920x720p) full HD resolution images with impressive image quality.

During old traditional surveillance system's upgrading and replacing, can't balance between achieving high definition surveillance and combining old traditional analog system become headache for users. In standard analog surveillance system, 960H is the highest resolution, to achieve much higher resolution becomes impossible mission for traditional surveillance system since its limitation from its technology.

If adopts all high definition (HD) IP camera, the entire system need to replace, this will not only generate high labor cost, but also significantly increased the project budget.

AHD (Analog High Definition) is new HD solution, AHD technology can transmit video signal over traditional coaxial cable up to 500 meters; it adopts advanced Y/C signal separation and analog signal filtering technology, which can effectively reduce color noise, and with better image reproduction. Compared with traditional analog cameras, AHD technology has significant improvement on imaging. Similar to IP camera, AHD's maximum resolution can reach up to 1080P.
