To do.
[0017]
In the present embodiment, since the intrusion detection unit 9 of the terminal 2 is provided with a reed switch, an unsteady signal indicating that an intruder has occurred when the window or door is opened or closed is transmitted. Even if 9 is an emergency button and the button is pressed, a non-stationary signal, that is, information indicating an emergency state is transmitted, and the same effect is obtained.
[0018]
FIG. 4 is an internal block diagram of the remote controller 3. An operation input unit 12 is a plurality of push button switches in this embodiment. The user can remotely operate the central processing unit 1 by pressing the push button switch. Remote operation here refers to controlling the central processing unit 1 to start or cancel the monitoring operation in the monitoring area. Reference numeral 13 denotes a terminal control unit, which is an operation signal from the operation input unit 12, that is, information that the user starts or stops monitoring the central processing unit 1, together with its own terminal device code. The data communication means 14 is used for wireless transmission. Reference numeral 15 denotes a display means. When the data communication means 14 receives a signal that the central processing unit 1 has confirmed that the remote control operation signal has been received, it blinks for a predetermined time or from the central processing unit 1 for a predetermined time or more.
