1.1. Camera device

After get the device list in home, you can determine whether it is a smart camera device based on the type of device. If it is a smart camera device, you can create a camera object based on the information in TuyaSmartDeviceModel.

1.1.1. Determine if it is a smart camera

You can determine the type of device according to the category property ofTuyaSmartDeviceModel. The category of the smart camera is sp.

Example

ObjC

[[TuyaSmartHomeManager new] getHomeListWithSuccess:^(NSArray<TuyaSmartHomeModel *> *homes) {
        [homes enumerateObjectsUsingBlock:^(TuyaSmartHomeModel * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
                TuyaSmartHome *home = [TuyaSmartHome homeWithHomeId:obj.homeId];
                [home getHomeDetailWithSuccess:^(TuyaSmartHomeModel *homeModel) {
                        [home.deviceList enumerateObjectsUsingBlock:^(TuyaSmartDeviceModel * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
                    if ([obj.category isEqualToString:@"sp"]) {
                        NSLog(@"%@ is a smart camera", obj.name);
                    }
        }];
        } failure:^(NSError *error) {

        }];
    }];
} failure:^(NSError *error) {

}];

Swift

let homeManager = TuyaSmartHomeManager()
homeManager.getHomeList(success: { homeList in
    homeList?.forEach({ homeModel in
        let home = TuyaSmartHome(homeId: homeModel.homeId)
        home?.getDetailWithSuccess({ _ in
            home?.deviceList.forEach({ deviceModel in
                if deviceModel.category == "sp" {
                    print(deviceModel.name!, "is a smart camera")
                }
            })
        }, failure: { error in

        })
    })
}) { error in

}

Note that the sample code here is only to show the simplest process of filtering out the camera device. In actual development, the device should be displayed and managed according to the logic of UI interaction.

1.1.2. Camera configuration information

After filtering out the smart camera devices, you can get the camera configuration information according to the device id, that is, the devId attribute ofTuyaSmartDeviceModel.

Configuration information needs to be obtained through Tuya open api.

Declaration

API Version Description
tuya.m.ipc.config.get (Deprecated) 2.0 Get p2p configuration information of camera
tuya.m.rtc.session.init 1.0 Get p2p configuration information of camera, and Tuya Cloud will send a offer to device, speed up the connection process

Parameters

Parameter Type Description Required
devId String Device id Yes

You need to use the TuyaSmartRequest class to request the Tuya open api, refer to the document Common Interface.

1.1.3. Camera instance

The SDK provides factory methods for creating camera configuration objects and camera control objects.

Class and Protocol

Class (Protocol) Description
TuyaSmartCameraFactory Utility class for creating camera configurations and camera objects
TuyaSmartCameraConfig Camera configuration class, developers do not need to care about its properties
TuyaSmartCameraType Camera interface protocol, there are different specific implementations depending on the type of camera firmware
TuyaSmartCameraDelegate Camera delegate, the result feedback of camera function method will be callback through delegate method

According to the data returned by the interface, use the TuyaSmartCameraFactory to create aTuyaSmartCameraConfig object as a parameter for creating a camera object. TuyaSmartCameraFactory related interfaces are as follows:

Declaration

Create camera configuration object.

+ (TuyaSmartCameraConfig *)ipcConfigWithUid: (NSString *) uid localKey: (NSString *) localKey configData: (NSDictionary *) data;

Parameters

Parameter Description
uid User uid, [[TuyaSmartUser sharedInstance] .uid
localKey Device key, TuyaSmartDeviceModel.localKey
data Configuration information obtained through the tuya.m.ipc.config.get api

Return

Type Description
TuyaSmartCameraConfig Camera configuration object

Declaration

Create a camera instance object.

+ (id<TuyaSmartCameraType>)cameraWithP2PType:(id)type config:(TuyaSmartCameraConfig *)ipcConfig delegate:(id<TuyaSmartCameraDelegate>)delegate;

Parameters

Parameter Description
type P2p type of camera
ipcConfig Camera configuration object
delegate Camera delegate

Return

Type Description
id The concrete implementation object of the camera interface

1.1.4. P2p type

The IPC SDK supports three p2p channel implementation. The SDK initializes different camera specific implementation objects according to the p2p type.

ObjC

id p2pType = [deviceModel.skills objectForKey:@"p2pType"];

Swift

let p2pType = deviceModel.skills["p2pType"]

Example

ObjC

id p2pType = [deviceModel.skills objectForKey:@"p2pType"];
[[TuyaSmartRequest new] requestWithApiName:@"tuya.m.ipc.config.get" postData:@{@"devId": deviceModel.devId} version:@"2.0" success:^(id result) {
    TuyaSmartCameraConfig *config = [TuyaSmartCameraFactory ipcConfigWithUid:[TuyaSmartUser sharedInstance].uid localKey:deviceModel.localKey configData:result];
    id<TuyaSmartCameraType> camera = [TuyaSmartCameraFactory cameraWithP2PType:p2pType config:config delegate:self];
} failure:^(NSError *error) {

}];

Swift

let p2pType = deviceModel.skills["p2pType"]
TuyaSmartRequest().request(withApiName: "tuya.m.ipc.config.get", postData: ["devId" : deviceModel.devId], version: "2.0", success: { result in
    let config = TuyaSmartCameraFactory.ipcConfig(withUid: TuyaSmartUser.sharedInstance().uid, localKey: deviceModel.localKey, configData: result as? [AnyHashable : Any])
    let camera = TuyaSmartCameraFactory.camera(withP2PType: p2pType!, config: config!, delegate: self)
}) { error in

}

Note that in the above code, the self passed in the delegate parameter needs to implement the TuyaSmartCameraDelegate protocol.
