Can I Delete Individual DVR/NVR Recordings from the Cloud or App?

No, this is not possible.
Recordings cannot be deleted individually from either the cloud or the recorder.

• Cloud recordings:
  These cannot be manually deleted. They are automatically overwritten based on your subscription plan and storage limits.
• Recorder-stored recordings:
  Individual deletion is not supported. You can only:
  • Format the hard drive to erase all recordings at once, or
  • Allow the system to overwrite the oldest recordings when the storage reaches full capacity.
