Can the property monitoring video automatically delete the review?

The storage medium of surveillance video is constantly erased, and it is difficult to recover the automatically deleted property surveillance video.

There are two common storage methods of monitoring system: memory card storage and hard disk video recorder storage. Memory card video file backup is relatively simple. You can remotely retrieve the monitoring video through the monitoring APP, and then download or record it. You can also take out the memory card and directly back up the video files in the memory card.

The copying and backup operations of monitoring video files of hard disk video recorder are the same. First, insert a U disk or a mobile hard disk into the USB port on the hard disk video recorder, then enter the hard disk video recorder and click the main menu-Backup, and then select the channel and specific time of the video file to be backed up. Then click Search, and the filtered surveillance video will be checked in the pop-up interface, and then click Backup.
