Cloud Storage

Tuya-enabled IP cameras (IPCs) support the cloud storage service that allows users to save video footage on the IPCs to the cloud.

Cloud storage process

• Determine whether a device supports cloud storage. If so, proceed with the process.

• Determine whether the cloud storage service is activated. Then, proceed with subsequent steps based on the service status.

  • If the cloud storage service is inactivated or has expired and all cloud-stored video files have been deleted, the cloud storage service must be purchased to enable the cloud storage service. After the cloud storage service expires, the existing cloud-stored video files will be retained for a period, seven days in most cases.

  • If the cloud storage service is within the validity period, get the date when the cloud-stored video files were created, and get the data of the specified date, including cloud storage events, timeline data, and authentication information. Then, a cloud storage event or a time point can be selected to start cloud-stored video playback.

  

Support for cloud storage

ThingSmartCloudManager provides a collection of cloud storage APIs, including those used to check the support for cloud storage capabilities.

API description

+ (BOOL)isSupportCloudStorage:(NSString *)devId;

Parameters

Parameter	Description
devId	The device ID.

Get key information

API description

+ (void)fetchSecretKeyWithDevId:(NSString *)devId completion:(ThingFetchSecretKeyCompletion)completion;

Parameters

Parameter	Description
devId	The device ID.
completion	The callback method.

Subscribe to cloud storage

To enable subscription to the cloud storage service, the Cloud Storage UI BizBundle must be integrated. This component provides the H5 pages and order display features for the subscription.

Parameters

Parameter	Description
devId	The device ID.

Configure cloud storage

After the subscription to the cloud storage service, users can upload video footage on an IPC to the cloud. Then, they can view and play back cloud-stored video footage based on the IPC SDK. Cloud storage is implemented with the class ThingSmartCameraKit in ThingSmartCloudManager.

Classes and protocols

Class name (protocol name)	Description
ThingSmartCloudManager	Cloud storage service status, video maintenance, and cloud-stored video playback
ThingSmartCloudManagerDelegate	Cloud-stored video playback, callback delegate for video frames

Initialize cloud storage

API description

To initialize ThingSmartCloudManager, pass in the device ID.

- (instancetype)initWithDeviceId:(NSString *)devId;

Enable encryption of cloud storage event images

You can set the image encryption state to YES, so the images in cloud storage events will be encrypted. In this case, the component ThingEncryptImage is used to display images.

API description

@property (nonatomic, assign) BOOL enableEncryptedImage;

Delegate callback for cloud-stored video data

The cloud storage delegate ThingSmartCloudManagerDelegate provides only one delegate method to return YUV data and frame data of each video frame. You can render video images with your own method. For this purpose, set the autoRender property of ThingSmartCloudManager to NO (default value: YES), and implement the delegate method to get YUV data of video frames. This way, the IPC SDK does not automatically render video images.

API description

- (void)cloudManager:(ThingSmartCloudManager *)cloudManager didReceivedFrame:(CMSampleBufferRef)frameBuffer videoFrameInfo:(ThingSmartVideoFrameInfo)frameInfo;

Parameters

Parameter	Description
cloudManager	The object ThingSmartCloudManager to play back cloud-stored video footage.
frameBuffer	The YUV data of video frames.
frameInfo	The information about video frames.

Load cloud storage data

Before cloud-stored video playback, cloud storage data must be loaded. The returned cloud storage data include the current status of the cloud storage service, encryption key, authentication information, and more.

API description

- (void)loadCloudData:(void(^)(ThingSmartCloudState state))complete

Parameters

Parameter	Description
complete	The success callback. The current cloud storage service status is returned.

Enum values of ThingSmartCloudState

Enum value	Description
ThingSmartCloudStateNoService	The cloud storage service is not activated.
ThingSmartCloudStateNoData	The cloud storage service is activated, but no video is available for playback.
ThingSmartCloudStateValidData	The cloud storage service is activated and videos are available for playback.
ThingSmartCloudStateExpiredNoData	The cloud storage service has expired, and no video is available for playback.
ThingSmartCloudStateExpiredData	The cloud storage service has expired, but videos are still available for playback.
ThingSmartCloudStateLoadFailed	Failed to load cloud storage service status

Query video recording date

After the cloud storage data is returned, if cloud-stored video footage can be played back, the cloudDays property indicates the date on which cloud-stored video footage can be played back.

API description

@property (nonatomic, strong, readonly) NSArray<ThingSmartCloudDayModel *> *cloudDays;
