NVP2431 + OV9712 AHD Board (32 or 38)


Haussworld, a professional designer and manufacturer of innovative, high-performance CCD boards & CMOS boards, today announces a new model AHD board - 9712 + 2431. This AHD board adopts with OmniVision OV9712 CMOS sensor technology and with Nextchip NVP2431H standard transmission technology which can reach to 720P HD resolution.


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
