What is N+1 Redundancy?
N+1 Redundancy is the surveillance solution containing an additional idle NVR server that is capable of handling the cameras when the primary NVR is unreachable.

How does it work?
There will be an additional NVR 3 server installed in the network which will stay idle and watch over the other NVR servers. By activating the redundancy service licenses (LRDS3000) in that idle NVR 3 server, it will have the capability to watch over the other NVR 3 servers. One redundancy server can monitor up to 16 other NVR servers. If any of those NVR servers becomes inaccessible, then the redundancy server will notice it and will immediately take over the camera management of the original NVR.

解决方案

The redundancy service is available for Windows-based NVR solutions, such as NVR 3 Corporate. There is no need for the additional software. The NVR 3 Corporate itself already contains all the necessary features to manage the redundancy. You only need to activate them by the licenses.
