9 If you know for a fact that the site is temporarily down for maintenance or

other issues, simply uncheck the Check Alive check box. In this case the

system will NOT initiate unnecessary tasks for a known problem and will return

to monitoring only after you check the box again.

Domain Database Synchronization

When a registration request from a child NVR is accepted — the NVR Domain Controller imports the NVR

cameras settings to the domain database held on the NVR Domain Controller. After that the domain

database will be synchronized automatically — any updates made in the cameras settings on the

NVR Domain Controller will be automatically propagated to the child NVRs and vise versa. However, the

synchronization could be lost if the connection between a child NVR and the domain controller is

temporary broken.

1. If the Connection Is Temporarily Broken

Notice that the DETEXI NVR domain continues to work in full configuration even if the connection

between a child NVR and the domain controller is temporarily broken. However, the updates for the domain

database at that time will be rejected; while the updates for a child NVR data from its own NVR Control

Center will be still allowed. If a child NVR cameras settings were updated during a connection failure the

synchronization with the domain database will be lost. However, child NVR users list is used by this NVR

only and its updating can not cause a synchronization failure.

y The synchronization must be restored when the connection is established.

y To synchronize the domain database with the child NVR updated settings the NVR data should

be imported to the domain database.

y The Domain Controller users list, its own cameras and tasks could be updated at any

circumstances.

2. Synchronization Failure Message

If a child NVR cameras settings were updated during a connection failure the synchronization with the

domain database will be lost. The synchronization must be restored when the connection is established by

importing the child NVR updated settings.

y The synch failure message will appear in the child NVR Control Center — General — Global

Settings under the NVR Controller Settings for HOST at the bottom.

y The message will also appear in the Domain Controller NVR Control Center — General — NVR

Locations.
