What action is needed to record a video using the device?

To record a video using the device, pressing and holding the button on the handle for approximately 2 seconds is the correct action. This method typically ensures that the device recognizes the command clearly and helps prevent accidental activations, which can occur if the button is pressed too quickly or inadvertently. Holding the button for a set duration allows the device to transition into recording mode, ensuring that the video captures the intended moment without interruptions.

Other methods, such as tapping the display or clicking the record button once, might be associated with different devices or modes but are less intuitive and can lead to missed recordings due to the immediacy required in starting a video. The option involving triple-tapping is also unconventional for initiating video recording, as it can be overly complicated and prone to errors. Thus, using a sustained press is generally the most reliable approach for beginning video capture.
