NVP2431 + AR0141 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 - NVP2431H + AR0141. This AHD board adopts with Aptina 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



Aptina AR0141 CMOS Overview :

This color image sensor is a 1/4-inch CMOS digital image sensor with an active-pixel array of 1280Hx800V. It captures images in either linear or high dynamic range modes, with a rolling-shutter readout. It includes sophisticated camera functions such as in-pixel bin ning, windowing and both video and single frame modes. It is designed for both low light and high dynamic range scene performance. It produces extraordinarily clear, sharp digital pictures, and its ability tocapture both continuous video and single frames makes it the perfect choice for a wide range of applications, including surveillance and HD video.


  • High-performance 1/4" CMOS image sensor, with megapixels of resolution
  • HD video, coaxial transmission control signal
  • Support Common 75-3 coaxial category lossless transmission up to 500 meters, stable performance, easy wiring
  • High-speed, long-distance, real-time transmission
  • AHD front end of the chip ISP and TX combined, with economic stability, lower power consumption
  • High-performance 3D noise reduction algorithm, superior low light performance
