Access the Page
Enter the above address in the browser, ensuring the URL contains the correct deviceId, channelId, startTime, endTime, and token parameters.

View Historical Video List
After the page loads, it will automatically query the historical video files based on the provided time range, and list all eligible video segments in the table below. Each segment shows the start time ~ end time (only hours, minutes, and seconds) and the channel number.

Play Historical Video
Click the play icon (▶) to the right of any historical video segment in the list. The page will start playing that segment. The player area will display the video stream.

The token is sensitive information. Please keep it secure and do not disclose it to others.

Loading the historical video list and starting playback may take some time; please be patient.

If playback fails or there is no historical video data, check whether the device is online and whether there are videos within the time range, or contact technical support.

VI. Obtaining Token

Refer to the "How to Obtain Token" section in the original document. Generate the token by calling the createToken interface using the API key and API Secret from the Developer project.
