Abstract
There is provided a device in which surroundings of a building can be monitored using a sensor; when detecting an intruder, an object can be detected even in the case of bad weather; and a predetermined area can be monitored using as few sensors as possible. The device includes a security system which emits a radio wave from a building to a predetermined area outside the building to detect an object, and on the basis of output of the object detecting unit, a judgment is made as to whether or not the object will intrude into the predetermined area.
