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.

The former is a wireless connection to the monitoring station, making it immune to power outages or someone cutting a cable. It is limited, however, with regard to transmitting large quantities of video, so many cellular primary systems incorporate broadband for video. Broadband primary services, on the other hand, have cables running down the side of a house that can be cut, thereby disabling the system. Some services offer cellular back up should this occur.
