security alarm monitoring
Once you start enjoying the security provided by your spanking new CCTV system, you will enjoy the option to add more cameras. But if you want that luxury, plan ahead. Do you want automatic redundant storage?Most NVRs can record only to one hard disk. 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.
