The DVR/NVR software saves the footage on external hard drives, USB Stick, and SD card of different sizes that enables you to save and view the videos later. But sometimes, hardware or software issues might occur that can lead to DVR/ NVR video corruption or footage loss. The CCTV security camera video loss issue can be related to:
Surveillance or CCTV camera videos and images are automatically recorded and archived via DVR/NVR in the hard drive, SSD, memory cards, USB drives, Cloud, or portable media players.
