nDVR has a recording limit of 30 hours. When checking, if it exceeds 30 hours, the saved file is no longer correct. I have to delete the old ones to save new files. But how to delete those old dvr, Is there any function or API that can delete them. Because it can’t be deleted manually. ---

Unfortunately, there is no way to do that through the API and it would require custom work. You could write a bash script or you could create an archive strategy.
