    Thermal Network Multi-spectral Pan & Tilt Camera

    Stock Code: TPC-PT8641D-B21105Z56-DC-DC48

    4-MEGAPIXEL
    CMOS
    IP CODE 66
    Brings thermal, color and infrared channels into one housing and sorts events by type.
    An uncooled thermal detector and a 4 MP visible channel work in the same pan and tilt housing. The camera supports heat, smoke and boat detection, separates human from vehicle on tripwire and intrusion events, and tracks the target automatically.

    Key features
    640 × 512pixels
    Thermal detector
    A detector with 12 µm pixel pitch covers the 8 µm–14 µm band behind an F1.0 aperture.
    56×
    Visible optical zoom
    The 6 mm–336 mm lens works across an F1.5–F5.3 aperture range.
    300m
    IR LED Distance
    The camera drives the illuminator in auto or manual mode.
    7inputs
    Alarm wiring
    Two alarm outputs drive external sirens and relays.
    99W
    Peak consumption
    Basic draw is 39 W and reaches 76 W with the illuminator alone on.
    IP66rating
    Outdoor endurance
    The housing operates from -40 °C to +70 °C and carries CE and FCC certification.
    DAY-TO-DAY USE
    Events sorted by typeThe camera tells heat, smoke and boat movement apart and follows the target on its own.
    Wide vertical sweepThe housing sweeps a wide angle upward and keeps the nearby surroundings in view.
    Remote managementONVIF, CGI and DaHuaSDK interfaces connect the camera to recording and management software.
    Usage AreaPort and coastal surveillance·Perimeter security·Smoke and heat based early warning
    The Micro SD card is optional.

    Note:
    ① Detection Distance: Detects objects, but cannot recognize their characteristics (objects must cover more than 3.6 pixels of the image).
    ② Recognition Distance: Classifies objects into general categories, such as human, vehicle (the object must cover more than 14 pixels of the image).
    ③ Identification Distance: Classifies objects into specific categories based on their characteristics, such as engineering truck, car (the object must cover more than 28 pixels of the image).
