9. How to backup video in NVR hard disk

①For the NVR host with two USB interfaces, directly insert the external hard disk or USB flash disk; if the NVR host only has one USB interface, you need to remove the hard disk, and then connect it to the computer for backup

②Go back to the main interface of the NVR system, open the video recording function, click the video backup, and then select the video to be backed up to export

(Users need to buy or have a USB splitter to facilitate the above operations)

Note: The NVR video cannot be downloaded on the SriHome App
