Health Advisory
Due to the nature of this content, which allows users to freely control the camera, it is produced in accordance with international safety standards and guidelines regarding visual display (such as flicker frequency and changes in brightness levels).
However, certain user actions may still produce unexpectedly strong visual stimuli.

[Rapid Camera Movements]
Rapid and intense camera movements—such as panning quickly from side to side, tilting up and down, or repeatedly zooming in and out—may cause fast motion across the screen and strong flickering.

[Sudden Approaches to Light Sources]
Suddenly moving the camera close to bright lights used in the live performance (such as stage lighting, lasers, fireworks, or effects), or filling the screen with a bright light source, may cause abrupt changes in brightness.
If you experience strong visual stimulation, dizziness, nausea, convulsions, or any vision abnormalities while viewing this content, stop immediately, look away from the screen, and take a break. If symptoms do not improve, promptly seek medical attention.

Please view this content at your own risk with thorough understanding of the above potential hazards. We kindly ask for your understanding and cooperation to ensure safe usage.
