<p>PURPOSE:To expand a detection area by constructing the title apparatus so that a detecting device can be moved by devices for rotation, declination and elevation and running. CONSTITUTION:Far infrared rays recognized by a sensor element 22 of a pyroelectric infrared sensor 21 are transmitted as information to a terminal and the whole of a monitoring apparatus is moved by a running device 25. When a rotation instruction from the terminal is transmitted to a rotating motor 27, the rotating motor 27 rotates in the direction of instruction under a speed control. Moreover, the instruction from the terminal is received by a declination- elevation control unit 34. The declination-elevation control unit 34 extends or contracts a shaft 32 for moving the sensor vertically. Since the pyroelectric infrared sensor 21 is fitted to the shaft 32 by a plug 31 for fixing the sensor, it is declined and elevated with the shaft 32 for moving the sensor vertically.</p> |
