    • A power monitoring section detects the interruption of AC electric power from a power line, and switches operating power within a camera to power from a battery. A control section sets control of the camera to a different mode at the power stopping time. The operation is controlled to pick-up one static image at constant time intervals, and sequentially stores the static image to a data storage section. A voice section stops collecting sounds. The control section stops communication with a master set. When the AC electric power is restored the operating power is switched to the electric power from the power line. When a user utilizing the master set knows the restoration of the power, the user gives commands for reading image information stored during the power stoppage to the camera, and monitors the state during the interruption of the AC electric power.
    • 电力监控部分检测来自电力线的AC电力的中断,并且切换相机内的操作电力以从电池供电。 控制部在停电时将摄像机的控制设定为不同的模式。 控制操作以以恒定的时间间隔拾取一个静态图像,并将静态图像顺序地存储到数据存储部分。 语音部分停止收集声音。 控制部分停止与主机的通信。 当AC电力恢复时,工作功率从电力线切换到电力。 当利用主机的用户知道电源的恢复时,用户给出了在停电期间存储的图像信息读取到摄像机的命令,并监视AC电力中断期间的状态。
