+# Distributed Camera Development
+
+## When to Use
+
+You can call the APIs provided by the **Camera** module to develop a distributed camera that provides the basic camera functions such as shooting and video recording.
+
+## How to Develop
+Connect your calculator to a distributed device. Your calculator will call **getCameras()** to obtain the camera list and traverse the returned camera list to check **ConnctionType** of the **Camera** objects. If **ConnctionType** of a **Camera** object is **CAMERA_CONNECTION_REMOTE**, your calculator will use this object to create a **CameraInput** object. The subsequent call process is the same as that of the local camera development. For details about the local camera development, see [Camera Development](./camera.md).
+
+For details about the APIs, see [Camera Management](../reference/apis/js-apis-camera.md).
+
+### Connecting to a Distributed Camera
+
+Connect the calculator and the distributed device to the same LAN.
+
+Open the calculator and click the arrow icon in the upper right corner. A new window is displayed. Enter the verification code as prompted, and the calculator will be connected to the distributed device.
+
+### Creating an Instance
+
+```js
+import camera from '@ohos.multimedia.camera'
+import image from '@ohos.multimedia.image'
+import media from '@ohos.multimedia.media'
+import featureAbility from '@ohos.ability.featureAbility'
+
+// Create a CameraManager object.
+let cameraManager
+await camera.getCameraManager(globalThis.Context, (err, manager) => {
+    if (err) {
+        console.error('Failed to get the CameraManager instance ${err.message}');
+        return;
+    }
+    console.log('Callback returned with the CameraManager instance');
+    cameraManager = manager
+})
+
+// Register a callback to listen for camera status changes and obtain the updated camera status information.
+cameraManager.on('cameraStatus', (cameraStatusInfo) => {
+    console.log('camera : ' + cameraStatusInfo.camera.cameraId);
+    console.log('status: ' + cameraStatusInfo.status);
+})
+
+// Obtain the camera list.
+let cameraArray
+let remoteCamera
+await cameraManager.getCameras((err, cameras) => {
+    if (err) {
+        console.error('Failed to get the cameras. ${err.message}');
+        return;
+    }
+    console.log('Callback returned with an array of supported cameras: ' + cameras.length);
+    cameraArray = cameras
+})
+
+for(let cameraIndex = 0; cameraIndex < cameraArray.length; cameraIndex) {
+    console.log('cameraId : ' + cameraArray[cameraIndex].cameraId)                          // Obtain the camera ID.
+    console.log('cameraPosition : ' + cameraArray[cameraIndex].cameraPosition)              // Obtain the camera position.
+    console.log('cameraType : ' + cameraArray[cameraIndex].cameraType)                      // Obtain the camera type.
+    console.log('connectionType : ' + cameraArray[cameraIndex].connectionType)              // Obtain the camera connection type.
+    if (cameraArray[cameraIndex].connectionType == CAMERA_CONNECTION_REMOTE) {
+        remoteCamera = cameraArray[cameraIndex].cameraId
+    }
+}
+
+// Create a camera input stream.
+let cameraInput
+await cameraManager.createCameraInput(remoteCamera).then((input) => {
+    console.log('Promise returned with the CameraInput instance');
+    cameraInput = input
+})
+```
+For details about the subsequent steps, see [Camera Development](./camera.md).
