Abstract

When a device management server requests obtainment of recorded video at the time of an error in an image forming apparatus, a device management client confirms that there is a request for obtainment of recorded video, and makes a request for desired recorded video to a camera management server. The device management server receives recorded video from the camera management server through the device management client.

Claims

1. A network system comprising a management system, in which network devices are managed, a client, and a camera system having a network camera,

the management system including:

a first memory storing instructions; and

a first processor which is capable of executing the instructions stored in the first memory causing the management system to;

manage device information of each of the network devices, wherein the device information includes device identification information of each network device;

manage camera identification information of a network camera in association with the device identification information of a managed network device which the network camera is capable of monitoring;

receive error log records recorded by a function of each network device;

store the received error log records into a database, wherein the camera identification information is not included in any error log record and the device identification information and time of error occurrence are included in each error log record;

provide an error device list screen based on the device information of each network device and the stored error log records;

designate a period of recorded data to be requested to the camera system, wherein the period of recorded data is designated by selecting a time backward from an error occurrence in a network device selected on the error device list screen; and

manage a first request including camera identification information and the designated period, the camera identification information being managed in association with the device identification information of the network device selected on the error device list screen, and

the client including;

a second memory storing instructions; and

a second processor which is capable of executing the instructions stored in the second memory causing the client to;

perform confirmation for existence of the first request to the management system;

obtain, as a result of the confirmation, the first request including the camera identification information and the designated period from the management system;

make a second request for recorded data to the camera system, using the camera identification information and the designated period;

receive recorded data in response to the second request from the camera system; and

transmit the recorded data to the management system.

2. The network system according to claim 1, wherein the instructions stored in the first memory further cause the management system to manage the camera identification information of a plurality of network cameras capable of monitoring the network device, a time zone during which each network camera monitors the network device, and image quality.

3. The network system according to claim 1, wherein the first request includes the camera identification information of a plurality of network cameras capable of monitoring the network device selected on the error device list screen.

4. The network system according to claim 1, wherein the instructions stored in the second memory further cause the client to:

make a recording request for recording by the network camera to the camera system, and

make a request for recorded data that is recorded in response to the recording request to the camera system.

5. The network system according to claim 1, wherein the recorded data that is transmitted to the management system is, with regard to a period during which recording by a plurality of network cameras overlaps, recorded data captured by one network camera selected based on image quality.

6. A device management method that is used by a network system including a management system, in which a network device is managed, a client, and a camera system having a network camera, the method comprising:

managing, by the management system, device information of each of one or more network devices, wherein the device information includes device identification information of each network device;

managing, by the management system, camera identification information of a network camera in association with the device identification information of a managed network device which the network camera is capable of monitoring;

receiving, by the management system, error log records recorded by a function of each network device;

storing the received error log records into a database, wherein the camera identification information is not included in any error log record and the device identification information and time of error occurrence are included in each error log record;

providing, by the management system, an error device list screen based on the device information of each network device and the stored error log records;

designating, by the management system, a period of recorded data to be requested to the camera system wherein the period of recorded data is designated by selecting a time backward from an error occurrence in a network device selected on the error device list screen;

managing, by the management system, a first request including identification information and the designated period, the camera identification information being managed in association with the device identification information of the network device selected on the error device list screen;

performing, by the client, confirmation for existence of the first request to the management system;

obtaining, by the client, the camera identification information and the designated period from the management system;

making a second request, by the client, for recorded data to the camera system, using the camera identification information and the designated period;

receiving recoded data in response to the second request from the camera system; and

transmitting, by the client, the recorded data to the management system.
