    Dahua Wireless External PIR-Camera (Only compatible with ARC3800H series)

    Stock Code: ARD2251E-W2(868V)

    Detects motion with PIR and microwave and verifies the event with an image.
    A wireless PIR-camera detector for outdoor and indoor use. It combines a PIR sensor with microwave detection; on alarm it sends a JPEG frame and confirms the event with an image.

    IP66Protection Grade
    Key features
    15m
    Wide detection range
    The PIR and microwave sensor scans at a 90° angle and reaches this range at an installation height of 1 m.
    1280 × 960pixels
    Image with the alarm
    It sends a JPEG frame at the moment of triggering, and infrared illumination covers the night.
    40kg
    Pet immunity
    Pets up to 80 cm tall do not trigger the alarm.
    24G
    Microwave support
    The microwave sensor measures alongside the PIR sensor and reduces false alarms.
    5years
    Long battery life
    CR123A × 4 batteries last up to this long in a scenario of 10 alarms per day.
    EVERYDAY USE
    Stable wireless linkTwo-way communication and frequency hopping keep the connection to the alarm hub.
    Remote updateIt refreshes the firmware from the mobile app, and dual backup recovers an interrupted update.
    Flexible mountingIt fits wall and pole mounting, and the adjustment switch on the housing sets the detection range.
    Usage AreaOutdoor·Indoor
    Works with the ARC3800H series only; the ARC3000H and ARA43 series are out of scope.
