  • MONITORING APPARATUS WITH A SENSOR UNIT
    Publication number: 20090322539
    Abstract: A monitoring apparatus includes a process unit, a sensor unit, a transmission unit and an illuminator unit. The sensor unit for detecting moving approaching objects is electrically connected to the process unit to send signals to the process unit. The transmission unit is electrically connected to the process unit for receiving signals from the process unit and adapted to be connected to a backend central control system for transmitting signals from the process unit to the backend central control system. The backend central control system sends a mode signal to the process unit via the transmission unit. The illuminator unit is electrically connected to the process unit and is controlled by orders from the process unit when the process unit determines status based on signals from the sensor unit and the mode signal.
