A method of communicating between an operator server and a user device for recording audio and/or video data includes the operator server receiving video data and/or audio data from the user device; the operator server initiating a session with an operator interface, wherein the session is initially in a pre-interaction mode and in response to receiving an instruction from the operator interface to change the session to an interaction mode, control the operator interface in order to change the session to an interaction mode, wherein, when in the interaction mode, a user of the user device and an operator of the operator interface are enabled to communicate with one another. The operator server is configured to begin recording of the video data and/or audio data before controlling the operator interface to change to the interaction mode and to continue recording received video data and/or audio data after said change.
