(Embodiment 4)
In the above embodiments, when the security sensor 1 detects, the notification means 10 of the security sensor 1, the notification means 12 of the corresponding notification terminal 4, or the notification means 16 of the receiver 2 is notified. However, the detection order of the district where the normal person moves home on the site and the security sensor 1 in the district is constant, but when there is a detection that deviates from this, it is reported that there is an intruder You may make it do.

That is, as shown in FIG. 9, in the normal case, the outdoor (X) crime prevention sensor 1 _{1X in the} district (A) → the shop side (Y) crime prevention sensor 1 _1Y → the indoor (Z) crime prevention sensor 1 _1Z of the place the order by the detection is made, for example, ya side (Y) security sensor 1 _1Z after operation, ya district security sensor 1 _2Y → district ya side of (B) (Y) (C ) When the detection operation is performed in an order different from normal, such as the security sensor _12Y on the side (Y), notification is performed.

In this case, for example, when the detection information of each security sensor 1 is collected and analyzed by the receiver 2 and the detection information is received in a detection order different from the normal detection order, the corresponding security sensor 1 or notification terminal device is received. The control information is sent to 4, and the notification means 10 is made to notify at the notification warning level set for each.
(Embodiment 5)
In each of the above embodiments, when the housekeeper comes home, it may be possible to instruct the receiver 2 to cancel the warning from a wireless transmitter or the like so that no warning is given when the housekeeper comes home. In order to prevent the use of a similar transmitter for canceling the warning, for example, an ID code for personal authentication is registered in the receiver 2 in advance, and an authorized person such as a household MA as shown in FIG. When the inside of the site is reached by a predetermined route while the device RC is transmitting, when the transmitted ID code is authenticated by the receiver 2, the warning state of the detection sensor or the security sensor in the area to be passed is released. Then, after the housekeeper MA passes, the control for setting the warning state again is performed based on the control information of the receiver 2.
(Embodiment 6)
By the way, although there are many cases where pets P such as cats and dogs are kept in the house H as shown in FIG. 11, there is a risk that the security sensor 1 installed indoors may detect these pets during warning. Therefore, in this embodiment, when the indoor security sensor 1 performs a detection operation, the signal processing circuit 11 of the security sensor 1 determines whether or not the security sensor 1 on the outdoor side or the shop side has already transmitted detection information. Thus, there is a feature in that a malfunction prevention function is provided so that the notification operation is not performed if there is no transmission.
