1# Requesting Camera Development Permissions 2<!--Kit: Camera Kit--> 3<!--Subsystem: Multimedia--> 4<!--Owner: @qano--> 5<!--SE: @leo_ysl--> 6<!--TSE: @xchaosioda--> 7 8The main process of camera application development includes development preparations, device input management, session management, preview, photo capture, and video recording. 9 10Before developing a camera application, you must request camera-related permissions (as described in the table below) to ensure that the application has the permission to access the camera hardware and other services. Before requesting permissions, ensure that the [basic principles for using permissions](../../security/AccessToken/app-permission-mgmt-overview.md#basic-principles-for-using-permissions) are met. 11 12- To use the camera for photo capture, request the ohos.permission.CAMERA permission. 13- To use the microphone to record audio, request the ohos.permission.MICROPHONE permission. 14- To display location information in photos or videos captured, request the ohos.permission.MEDIA_LOCATION permission. 15 16All these permissions must be authorized by users through a dialog box. For details about how to request and verify the permissions, see [Declaring Permissions](../../security/AccessToken/declare-permissions.md) and [Requesting User Authorization](../../security/AccessToken/request-user-authorization.md). 17 18- To read images or videos, you are advised to use the media library [Picker to access them](../medialibrary/photoAccessHelper-photoviewpicker.md). 19- To save images or videos, use the [security components to save them](../medialibrary/photoAccessHelper-savebutton.md). 20 21> **NOTE** 22> 23> When the application needs to clone, back up, or synchronize images and videos in users' public directory, request the ohos.permission.READ_IMAGEVIDEO and ohos.permission.WRITE_IMAGEVIDEO permissions for reading and writing audio files. For details, see <!--RP1-->[Requesting Restricted Permissions](../../security/AccessToken/declare-permissions-in-acl.md)<!--RP1End-->. 24
