Backup drives |
√ |
√ |
One or more drives may be assigned to operate as backup drives: they will be used for recording only in case of failure of all the main drives; at that, once one of the main drives becomes available, the recording to the backup drives will stop |
Cold backup of servers |
√ |
√ |
In case of failure of the server with the USB protection key, it is possible to transfer the USB key to a cold redundancy server with the pre-installed Eocortex application, then activate the current license bound to the USB key on the given server. In a multiserver system, it is sufficient to connect the new server to the system and assign the cameras of the failed server to it; at that, all the camera settings will be saved. In the single-server system, it will be required to use the camera configuration file saved before |
Self-diagnostics |
√ |
√ |
In the course of operation, the video surveillance system components perform automatic self-diagnostics, informing the users about the issues encountered and giving recommendations regarding their rectification |
Increased database reliability |

In case of a failure of the server itself or all of its drives, the cameras assigned to it will be processed by other servers, including the broadcasting of the real-time video and the recording to the archive. In case of the fast backing up, the switching to the redundancy server happens within 10 seconds from the moment of losing the connection with the main server In case of the constant backing up, connecting to cameras is performed continuously from two servers that process and archive videos from these cameras. In case one of the servers is down, the video and archive data will be available on another server |
