Your recorder’s hard drives are what keep your surveillance system useful. This guide explains how SureVision storage works, how to think about recording schedules and retention, and how to check the health of your NVR hard disks. Set when cameras record and how long footage is kept based on your storage capacity and retention needs. Configure image snapshots by schedule, motion, alarm, or event trigger, with adjustable image quality and intervals. Manage disks, storage allocation, disk groups, and advanced settings, and review HDD status directly from the NVR. SureVision includes built-in hard-drive health checks. Under maintenance, you can review HDD Status, run a S.M.A.R.T. Test, and start Bad Sector Detection to identify disk problems before they affect your recordings. Start the test and watch the live progress in the Status column. Results are reported as Healthy, Failure, or Bad Sectors. SureVision can scan a drive in read-only mode to find damaged areas. Good sectors and damaged sectors are shown differently on the results screen. If the system reports Failure or shows bad sectors, replace the disk as soon as possible to avoid losing recordings. The manual also covers RAID arrays, disk groups, space allocation, redundant recording, and redundant snapshot support on certain models. These features are useful for larger systems that need better data protection and organized storage management.SureVision Storage & HDD Health Guide
