Instek Digital™ NVR Failover server is a redundant NVR server - which automatically takes over operation of the NVR server in case of a malfunction. Ensuring non-stop NVR recording - Instek Digital™ designed the NVR Failover server.


Instek Digital™ system architecture has been designed to eliminate single point of failure and allow maximum uptime. The distributed architecture of Instek Digital allows any failover NVR to take over the operations of a failover NVR. Even a failing NVR FO can be taken over. In contrast with a central architecture - which requires a central server and risk single point of failure. Instek Digita™ distribute architecture provides flexibility - without any risk of video-loss.

Instek Digital™ distributed architecture - multiple NVR’s are connected to the network and in any case a failure occurs - Instek Digital’s NVR Failover server (NVR-FO) will take over the functionalities of the original failing NVR. This results in a seamless operation without any interruption. N represents the operation of the host and S represents the standby host.
