The imaging devices each capture an image of an imaging area including the detection target to generate captured image data indicating a captured image. The storage stores therein a detection range in the captured image. The controller detects a change to the captured image in the detection range based on the captured image data. The controller determines one of the imaging devices that has provided a captured image whose image exhibiting a portion of the detection target has a larger area among the captured images to be a main imaging device. Upon detecting a change to a captured image in the detection range captured by the main imaging device, the controller changes the detection range of the main imaging device so that the detection range encloses the detection target image. ## Claims ### Claim 1 A monitoring system for detecting an event happening to a detection target, comprising: a first imaging device configured to capture an image of a first imaging area including the detection target to generate first captured image data indicating a first captured image; a second imaging device configured to capture an image of a second imaging area differing from the first imaging area to generate second captured image data indicating a second captured image; first storage configured to store therein data indicating a detection range; a controller configured to detect a change to the first captured image or the second captured image in the detection range based on the first captured image data or the second captured image data; and a notification device configured to notify a user of information, wherein the detection range includes a detection target image exhibiting the detection target, in a situation in which the first captured image and the second captured image respectively include images exhibiting different portions of the detection target, the controller determines one of the first and second imaging devices that has provided a captured image whose image exhibiting a portion of the detection target has a larger area among the first and second captured images to be a main imaging device, in a situation in which the first captured image or the second captured image includes an image exhibiting a portion of the detection target, the controller directs the notification device to notify the user of a message prompting the user to move the detection target so that one imaging device of the first imaging device and the second imaging device that captures the image exhibiting the portion of the detection target captures an image of an entirety of the detection target, and determines an imaging device capturing the entirety of the detection target to be a main imaging device, and upon detecting a change to a captured image in the detection range captured by the main imaging device, the controller changes the detection range of the main imaging device so that the detection range encloses the detection target image. ### Claim 2 (depends on 1) The monitoring system according to claim 1, wherein the controller acquires a change in size of the detection target image and changes the detection range depending on the change in the size of the detection target image. ### Claim 3 (depends on 1) The monitoring system according to claim 1, further comprising: second storage configured to store therein a recognition image of the detection target, wherein in a situation in which a percentage of match between the recognition image and the detection target image is lower than a threshold, the controller directs the notification device to notify the user of a message prompting the user to change orientation of the detection target be changed. ### Claim 4 (depends on 3) The monitoring system according to claim 3, wherein the recognition image is an image indicating a shape of the detection target. ### Claim 5 (depends on 3) The monitoring system according to claim 3, wherein the recognition image is an identification image that identifies the detection target. ### Claim 6 A monitoring system for detecting an event happening to a detection target, comprising: an imaging device configured to capture an image of an imaging area including the detection target to generate captured image data indicating a captured image; first storage configured to store therein data indicating a detection range in the captured image; and a controller configured to detect a change to the captured image in the detection range based on the captured image data, wherein the detection range includes a detection target image exhibiting the detection target, the controller determines whether or not any portion of an outline of the detection range falls outside of the captured image, and in a situation in which a portion of the outline of the detection range falls outside of the captured image, the controller changes a position of the detection range so that an entirety of the outline of the detection range is located within the captured image. ### Claim 7 (depends on 6) The monitoring system according to claim 6, wherein the controller acquires a change in size of the detection target image and changes the detection range depending on the change in the size of the detection target image. ### Claim 8 (depends on 6) The monitoring system according to claim 6, further comprising: a notification device configured to notify a user of information; and second storage configured to store therein a recognition image of the detection target, wherein in a situation in which a percentage of match between the recognition image and the detection target image is lower than a threshold, the controller directs the notification device to notify the user of a message prompting the user to change orientation of the detection target be changed. ### Claim 9 (depends on 8) The monitoring system according to claim 8, wherein the recognition image is an image indicating a shape of the detection target. ### Claim 10 (depends on 8) The monitoring system according to claim 8, wherein the recognition image is an identification image that identifies the detection target.
