This means data storage is not redundant – a hard disk failure or theft of the NVR would mean that you lose all your recorded footage. USB backup is supported on most NVRs to mitigate against this risk but ideally the NVR should have at least 2 hard disk bays and automatically write a copy of the footage to the second hard drive. The other option to explore is whether the NVR can write the footage to a remote network location such as a NAS. To learn more about surveillance hard drives, check my latest guide.
