概述

What is Redundancy Service? There may be situations where the NVR server may become inaccessible, and the cameras have no recorder to send the video stream to. It could happen due to the network failure, data switch failure, power outage, human error or due to any other reasons. Even though such incidents are very unlikely to happen, the mission critical solutions should have a protection against that.

The seamless service can be achieved by using NVR Redundancy Service. It would ensure that whenever the original NVR is not accessible, the alternative system will immediately step in and start recording the video streams of the cameras belonging to the original NVR.

ACTi offers two kinds of Redundancy Service solutions: N+1 and N-to-N.

N+1 冗餘 N+1 冗餘是一種監控解決方案，包含一個額外的閒置 NVR 伺服器，當主要 NVR 無法連線時，此伺服器能夠處理攝影機。 閱讀更多。

N-to-N 冗餘 N-to-N 冗餘是一種監控解決方案，包含一組 NVR 伺服器，除了執行其主要錄影任務外，還能相互監控並接管無法連線的 NVR 的攝影機錄影任務。 閱讀更多。

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.
