Hi innovate, Thanks for using Zoom SDK. Do you mean you would like to ask the user for the camera permission after pressing your custom button? In our iOS SDK, we do not have a method for requesting camera permission individually. As long as you have set up the camera permission description in the `info.plist` file, you should be fine with the camera permission. Once the meeting starts, and the video is triggered, if our SDK detects that the camera is not on and not yet being asked for a permission, our SDK will ask the user for the permission. If you would like to ask for camera permission before the meeting, then you can do it without our SDK, the following links could be helpful: - [https://developer.apple.com/documentation/avfoundation/cameras\_and\_media\_capture/requesting\_authorization\_for\_media\_capture\_on\_ios?language=objc](https://developer.apple.com/documentation/avfoundation/cameras_and_media_capture/requesting_authorization_for_media_capture_on_ios?language=objc) - [https://stackoverflow.com/questions/26070393/is-there-a-way-to-ask-user-for-camera-access-after-they-have-already-denied-it-o](https://stackoverflow.com/questions/26070393/is-there-a-way-to-ask-user-for-camera-access-after-they-have-already-denied-it-o) - [https://stackoverflow.com/questions/27646107/how-to-check-if-the-user-gave-permission-to-use-the-camera](https://stackoverflow.com/questions/27646107/how-to-check-if-the-user-gave-permission-to-use-the-camera) - [https://developer.apple.com/documentation/avfoundation/cameras\_and\_media\_capture?language=objc](https://developer.apple.com/documentation/avfoundation/cameras_and_media_capture?language=objc) - [https://stackoverflow.com/questions/39631256/request-permission-for-camera-and-library-in-ios-10-info-plist](https://stackoverflow.com/questions/39631256/request-permission-for-camera-and-library-in-ios-10-info-plist) Hope this helps.

Hi, Thanks for the reply and the clarification. What kind of camera control are you looking for? We have an interface to ask/request the participant/user to start video/camera: ```auto askUserStartVideo ``` [https://zoom.github.io/zoom-sdk-ios/category\_mobile\_r\_t\_c\_meeting\_service\_07\_video\_08.html#aa4d28c13634f025d6371ea2597163251](https://zoom.github.io/zoom-sdk-ios/category_mobile_r_t_c_meeting_service_07_video_08.html#aa4d28c13634f025d6371ea2597163251) We also have an interface to stop the participant/user’s camera: ```auto stopUserVideo ``` [https://zoom.github.io/zoom-sdk-ios/category\_mobile\_r\_t\_c\_meeting\_service\_07\_video\_08.html#aab328693e8dfba7af5071fe19af035f0](https://zoom.github.io/zoom-sdk-ios/category_mobile_r_t_c_meeting_service_07_video_08.html#aab328693e8dfba7af5071fe19af035f0) We have a bunch of options that controls the videos/cameras, you can find more info here: [https://zoom.github.io/zoom-sdk-ios/category\_mobile\_r\_t\_c\_meeting\_service\_07\_video\_08.html#aab328693e8dfba7af5071fe19af035f0](https://zoom.github.io/zoom-sdk-ios/category_mobile_r_t_c_meeting_service_07_video_08.html#aab328693e8dfba7af5071fe19af035f0) Hope this helps.
