    What is a AHD System?

    AHD means Analog high definition.AHD technology is able to realize long distance on a transmission based on the existing analog; the adoption of advance Y/C signals separation and analog filtering technology can effectively reduce the color noise on hign frequency area with better real images. Compared to traditional analog HD product, AHD monitor image quality has a qualitative leap and ascension


    8 Features of HD Products

    1. Clearer - advanced bright color saparation,signal filtering, 3D noise reduction technology,higher image resolution, better image reductibility
    2. Longer transmission - Coaxial trasmission coommon 75-3 cable upto 500meters
    3. Zero Delay - Front-end data without coding compression to the back-end,real time high fidelity
    4. Good Compability - Compatible with ordinary D1/960 h, compatible with analog peripherals (including distributors, matrix, etc.)
    5. Easy Operation - Support OSD menu design, with what you want, you need
    6. Cheap Price & High Quality - common simulation, HD quality products
    7. High Integration - AHD front-end chip prices, high quality products
    8. Open Standards
    How Does AHD Image Quality Compare to HD IP & HDCVI Cameras?

    AHD Camera can be directly connected to the CRT display through coaxial cable, image display properly. HDCVI camera connect the monitor directly by coaxial cable , no image (black screen). HDCVI camera by connecting HDCVI VCR, HDCVI hardisk video recorder HDMI output to the LCD display, the image is normal. So it seems, AHD the camera has 960h output modes, very convinient for debugging. And 1mp AHD camera image effect and analoh cameras effect is not abvious defference, so AHD camera output 960h signal can reflect the effect of 720p
