After an IP camera detects intelligent alert events, the IP camera uploads images and video files to IoT Platform. This topic describes how to configure the intelligent alerting feature.
Prerequisites
An IoT Platform instance of the video type is purchased, and a video device is connected to IoT Platform. For more information, see Device Connection.
Device-side development
Device-side development is required when your IP camera is directly connected to IoT Platform. For more information, see Device-side development.
Cloud-side development
If you want to perform cloud-side development, you can perform one or more of the following operations supported by LinkVisual on intelligent alert events:
View the type of an intelligent alert event
Log on to the IoT Platform console. On the Overview page, click the name of the video instance that you created.
In the left-side navigation pane, choose Devices > Products.
On the Products page, find the product for which you want to add features, and click View in the Actions column.
Click Define Feature. In the Default Module section of the Define Feature tab, click View in the Actions column of IntelligentAlarm.
In the ViewSelf-Defined Feature dialog box, click View in the Output Parameters section.
In the View Parameters dialog box, click View in the Parameter Name: Alert Type row of the JSON Objects section. All types of intelligent alert events are displayed in the View Parameters dialog box.
Query intelligent alert events that are uploaded by a camera
You can call the QueryDeviceEvent operation to obtain intelligent alert events that are uploaded by a camera.
Query images that are related to intelligent alert events
You can call the QueryDeviceEvent operation to obtain intelligent alert events that are uploaded by a camera.
You can call the QueryDeviceEventPicture operation to query the related images by using the IDs of the intelligent alert events that are returned from the QueryDeviceEvent operation in Step 1.
Query videos that are related to intelligent alert events
You can call the QueryDeviceEvent operation to obtain intelligent alert events that are uploaded by a camera.
You can call the QueryDeviceEventRecord operation to query the related videos based on the IDs of the intelligent alert events that are returned from the QueryDeviceEvent operation in Step 1.
Application-side development
Before you use image-related features, you must complete application-side development. For more information, see Application-side development.
