Thanks for reaching out to us. Video files cannot be downloaded from the publish link, but since this is a camera of your own, you would just need to login to your account. From the my cameras page, you can access the folder list under the camera thumbnail to download specific clips. If you are planning to download many video clips, you should use FTP rather than the web browser to complete the download tasks.
Please reach out to email@example.com if you need further assistance.
