MONITORING APPARATUS, MONITORING SYSTEM, AND MONITORING METHOD
A monitoring apparatus is connected to a shutter which opens and closes to limit a capturing area of an image capturing device. The monitoring apparatus detects an event indicative of a closing event or an opening event, and controls the shutter to open and close based on a given time schedule and the detected event, where the time schedule determines each period for opening and closing the shutter. The monitoring apparatus controls the shutter based on the opening event in response to a detection of the opening event, and controls the shutter based on the time schedule in response to a detection of the closing event when the opening event is last detected before the detection of the closing event.

7 . The monitoring apparatus according to claim 1 , wherein
the first controller is configured to control the shutter to close in response to the detection of the closing event by the event detector when the shutter is in an opened state based on the given time schedule, independently of the opening event.
8 . The monitoring apparatus according to claim 1 , further comprising:
a second controller, configured to record images captured by the image capturing device in a memory, wherein
the second controller is configured to start or stop recording the images in response to the detection of the event by the event detector.
9 . The monitoring apparatus according to claim 1 , wherein
a sensor is connected to the monitoring apparatus, and
the event detector is configured to detect the event based on information sent from the sensor.
10 . The monitoring apparatus according to claim 1 , further comprising
a communication unit, configured to receive information, wherein
the event detector is configured to detect the event based on the information received by the communication unit.
11 . The monitoring apparatus according to claim 1 , further comprising:
a third controller, configured to record a sound collected by a microphone provided in an area in which the image capturing device is disposed, wherein
the third controller starts or stop recording the collected sound in response to the event detected by the event detector.
12 . The monitoring apparatus according to claim 1 , further comprising:
a second controller, configured to record images captured by the image capturing device in a memory; and
a third controller, configured to record a sound collected by a microphone provided in an area in which the image capturing device is disposed, wherein
the first, second and third controller are operated in accordance with an operation mode indicated by the given time schedule.
13 . A monitoring system comprising:
