Parameter | Type | Required | Example | Description |
---|---|---|---|---|
Action | String | Yes | TriggerCapturePicture |
The operation that you want to perform. Set the value to TriggerCapturePicture. |
ProductKey | String | No | a1BwAGV**** |
The ProductKey of the product to which the IP camera belongs. You can view the information about all products within the current account on the Products page of the IoT Platform console or by calling the QueryProductList operation. Notice If you specify this parameter, you must also specify the DeviceName parameter.
|
DeviceName | String | No | camera1 |
The DeviceName of the IP camera. You can view the DeviceName of the IP camera on the Devices page of the IoT Platform console. Notice If you specify this parameter, you must also specify the ProductKey parameter.

IotId | String | No | zLZyi6aOLyOSHa9hsPyD00**** |
The ID of the IP camera. IoT Platform allocates an ID to each IP camera to uniquely identify the IP camera. You can call the QueryDeviceDetail operation of IoT Platform to query the ID of the IP camera. Notice If you specify this parameter, you do not need to specify the ProductKey or DeviceName parameter. The IotId parameter specifies a GUID of the IP camera, which corresponds to a combination of
the ProductKey and DeviceName parameters. If you specify both the IotId parameter and the combination of the ProductKey and DeviceName parameters, the IotId parameter takes precedence.
