NVP2441 + SONY 323 AHD Board (32 or 38)




Haussworld, a professional designer and manufacturer of innovative, high-performance CCD boards & CMOS boards, today announces a new model FOUR-IN-ONE AHD/TVI/CVI/CVBS board - NVP2441H + SONY IMX323. This board adopts with SONY CMOS sensor Exmor technology and with Nextchip NVP2441H standard transmission technology which can reach to 1080P HD resolution (2 million pixels).


Coaxial HD & AHD Overview :

  • Reliable Long-Distance Transmission

With this new AHD technology, 720P signal can be transited to 500 meters distance and 1080P signal can be transited to 300 meters with 75-3 coaxial cable. By comparison of SDI HD technology, 200 meters is the transfer limit through better materials cable and 100 meters is the transfer limit through ordinary coaxial cable.

  • Real time HD Transmission Technology

Non-latency reliable video transmission without additions of relay devices. It is free from IP hassles and also features a no-latency reliable video transmission without additional relay devices for real-time performance.

  • Composite Signals In 1 Coaxial Cable For Simple Installation

AHD composites video, audio and control signals together and then transmits them over one coaxial cable. Because of this nature of AHD, it eventually simplifies the installation for upgrading analog HD seamlessly with the low-cost conventional analog system topology. At the same time, it supports reverse control that can simulate the camera OSD menu from the front-end equipment.

  • Anti-interference Capability

Strong anti-interference capability & solid interface protection that can avoid space high frequency electromagnetic radiation to ensure a constant signal transmission of high definition video display without problems as frame drop and lock loss occurred.

  • Good Compatibility & Different Specifications All In One AHD DVR

Competiable with normal D1 / 960H, and analog peripherals (including distributors, matrix, etc.). Switch AHD, IP and Anolog video signal from AHD DVR in no time.

  • Cost Advantage

More cheaper than CVI & SDI solution,  ordianary analog price, but with high-definition quality


 SONY IMX323 CMOS Overview :


The release of IMX323 CMOS sensor enables manufacturers to produce cost-effective high quality HD video products without adding extra cost. 




IMX323 is a 1/2.9 inch 2.19 megapixel CMOS image sensor, it achieves a compact package size by utilizing WLCSP (Wafer level chip size package) technology. However, IMX323 still can maintain low illumination performance equal to that of the predecessor SONY IMX222 that offered ehanced sensitivity in the near IR region for video surveillance & security applications.
