    IRIS CONTROL Fixed Iris

    In indoor environments where light levels may be constant the iris opening cannot be adjusted and is fixed at a certain f-number

    f-stop that cannot be varied.

    Manual iris

    iris can be adjusted by turning a ring on the lens to open or close the iris.

    This is not convenient in environments with changing light conditions

    Auto Iris It's motor-driven, automatically adjustable iris opening that responds to

    changes in light levels

    The ability to adjust automatically to lighting conditions.

    DVR

    Analog signal from the camera one-directional

    signal carrier

    The analog video signals travel, the weaker they

    become.

    A lot of noise might be coupled into the analog

    video signals

    NVR

    multi-directional Information transporting

    Records the images from different IP Camera

    High image quality, Storage is much moreflexible , Cost-effective

    CCTV futures whats next?

    Fusion Cameras (high-resolution and thermal)

    Intelligent Cameras with embedded software

    Enhanced CMOS cameras with higher color rendition and low-light capacity

    360 mirror cameras with intelligent software

    Smaller, lighter, wireless cameras

    Iris-based biometric devices analyze the features found in the colored ring of tissue that

    surrounds the pupil.

    recognition solutions analyze-facial characteristics with geometric point algorithms. It

    requires a digital camera to develop a facial image of the user for authentication andcompares the image to a database

    Biometric - Thermal
