Abstract

A monitoring system includes a plurality of image-capturing apparatuses each including an event detector that executes on a corresponding captured image at least one of a plurality of processing algorithms for detection of a monitor event, and a transmission controller that outputs to a network only a processing result of the executed processing algorithm when a monitor event is not detected and that outputs to the network at least the captured image when a monitor event is detected; and a management apparatus managing the plurality of image-capturing apparatuses via the network and including an event determination unit that determines occurrence of a monitor event in accordance with the received processing result and a record controller that records the received captured image.

Claims

1. A monitoring system comprising:

a plurality of image-capturing apparatuses including

an event detector configured to process first event detection on a corresponding captured image for a first event, and

a transmission configured to output to a network a processing result of the first event detection without the image when a request for the image is not received and to output to the network a processing result of the first event detection with the captured image when the request for the image is received; and

a management apparatus including

a receiving unit that receives data from the plurality of image-capturing apparatuses via the network,

an event determination unit that determines occurrence of a second event in accordance with the received processing result of the first event detection, and

a request sending unit that sends the request for the image to the image-capturing apparatus when the second event occurs,

wherein the second event is at least one of moving object detection and non-moving object detection.

2. The monitoring system corresponding to the claim 1, wherein

result of the first event detection at the event detector includes information indicating intrusion of a moving object into a set area.

3. The monitoring system corresponding to the claim 2, wherein

result of the first event detection at the event detector includes position information relating to the detected moving object.

4. The monitoring system corresponding to the claim 1, wherein

result of the first event detection at the event detector includes information indicating existence of a non-moving object in a set area.

5. The monitoring system corresponding to the claim 1, wherein

the event detector configured to integrate plural areas, wherein motion is detected in each moving object.

6. The monitoring system corresponding to the claim 1, wherein

the management apparatus further includes a record controller that records the received captured image.

7. An image-capturing apparatus comprising:

an event detector configured to process first event detection on a corresponding captured image for a first event, and

a transmission configured to output to a network a processing result of the first event detection without the image when a request for the image is not received and to output to the network a processing result of the first event detection with the captured image when the request for the image is received; and

wherein a management apparatus configured to determine occurrence of a second event in accordance with a received processing result of the first event detection and send the request for the images to the image-capturing apparatus when the second event occurs;

wherein the second event is at least one of moving object detection and non-moving object detection.

8. The monitoring apparatus corresponding to the claim 7, wherein

result of the first event detection at the event detector includes information indicating intrusion of a moving object into a set area.

9. The monitoring apparatus corresponding to the claim 8, wherein

result of the first event detection at the event detector includes position information relating to the detected moving object.

10. The monitoring apparatus corresponding to the claim 7, wherein

result of the first event detection at the event detector includes information indicating existence of a non-moving object in a set area.

11. The monitoring apparatus corresponding to the claim 7, wherein

the event detector configured to integrate plural areas, wherein motion is detected in each moving object.

12. A monitoring system comprising:
