6.4 Cluster Service
The cluster function, also known as cluster redundancy, is a kind of deployment method that can
improve the reliability of the device. In the cluster system, there is a number of main devices and
another number of sub devices (the N+M mode), and they have a virtual IP address (the cluster IP).
When the main device fails, the corresponding sub device will take over the job automatically. When
the main device recovers, the sub device will transmit the configuration data, cluster IP address and
videos recorded during the failure to the main device which then takes over the job again.
In the N+M cluster system, there is a management server, the DCS (Dispatching Console) server,
which is responsible for timely and correct scheduling management of the main and sub devices.
When you create a cluster, the current device is used as the first sub device and the DCS server by
default.
This function is available on select models.
6.4.1 Configuring Cluster IP
When the main device malfunctions, the sub device can use the main device configuration and
virtual IP address to replace the work (monitor or record) accordingly. When you use the virtual IP to
access the device, you can still view the real-time video and there is no risk of record loss.
