Provided is a monitoring device which can be easily installed in various locations and with which it is possible to adequately respond to unforeseen circumstances. A monitoring device 1 that can be installed in a desired position, wherein the monitoring device 1 comprises: a monitoring camera 11 capable of photographing an object to be detected; a detection sensor 14 that detects the presence of the object to be detected within a prescribed detection range; a GPS sensor 13 that acquires current position coordinate values for the GPS sensor 13; and a control unit 30 that receives and processes a detection signal from the detection sensor 14 and a current position coordinate value signal, and transmits a control signal to the monitoring camera 11; the control unit 30 being configured so as to: store an initial installation coordinate value when the monitoring device 1 is installed in the desired position; receive a detection signal detecting the presence of the object to be detected; determine, on the basis of a disparity between the initial installation coordinate value and the current position coordinate value, that there is a high possibility of an abnormal state caused by a main unit being moved by a person; and transmit to the outside.
