Switch to Redundancy Storage
An NVR server can serve as Redundancy Storage for other NVR servers. It records all
surveillance videos directly from camera devices, logs and performs actions for real-time event
notifications on behalf of the NVR server during system downtime. Authorized users may also
access the Redundancy Storage when it is in use for live-monitoring or playback options. After
the NVR server becomes available, the Redundancy Storage service will then automatically
synchronize all recorded video and events back to the NVR server.
Before you start,
1. Prepare a specific computer to be dedicated to carrying out the redundancy tasks.
2. Purchase the redundancy storage service license from ACTi sales representative.
One redundancy storage computer will require one license, which can serve maximum
sixteen (16) NVR servers.
3. If your are going to install the redundancy storage on a computer, please go to

the computer.
Remember, by switching an NVR server into a redundancy storage, the original settings and
recordings of it will all be overwritten.
