DETEXI Basic Configuration 25 - 31
Domain Configuration Health Monitoring
What Can Be Done?
What can be done to ensure the DETEXI domain configuration health? First of all, the reliability settings
should be configured for each NVR in the domain. Then — be aware weather all child NVRs are alive and
properly respond to the domain controller. And finally, the domain database held by the NVR Domain
Controller should always be synchronized with the child NVRs data.
1. DETEXI Reliability System
IP-surveillance system reliability minimizes the risk of system failure and associated down-time, therefore a
designated person or persons should be aware of the DETEXI system status at any given time. There are
several areas that should be checked to insure that you have a healthy and functioning system —
y Is the NVR running at all (power is OFF or ON)
y Are all selected NVR components running
y Are all cameras with an active schedule functioning and being recorded
y Is there enough space to make a recording
y Are there enough system resources to make a recording
y Is the NVR Domain Controller network and all it’s child NVRs healthy and running
To address the issue the DETEXI Reliability System is embedded into the software. Every NVR, including
NVR Domain Controller in the domain configuration should have its own reliability settings. In this case if
something happens to the system, hardware or one of the NVR components, certain task assigned to this
event automatically informs the system administrator about the problem.
For the detailed instructions on how to setup the system health monitoring, refer to the DETEXI NVR —
Reliability System and the DETEXI NVR — Event Management — Task Triggers — System Health
manual.
2. Child NVR Health Monitoring
Although every NVR in the domain configuration should have its own reliability settings there is a new
intercommunication layer between the NVR Domain Controller and a child NVR, which could also fail and
therefore the system administrator must be able to check its status. To be aware weather all child NVRs
are alive and properly respond to the domain controller you should launch Check Alive procedure to setup
Task when NVR does not respond for each child NVR in the domain controller NVR Control Center.
3. Domain Database Synchronization
The NVR Domain Controller supports the domain database synchronization automatically, but it can be
lost if during the system configuration the connection between a child NVR and the Domain Controller was
broken.
y The synchronization must be restored when the connection is established.
y The DETEXI NVR domain continues to work in full configuration even if the connection
between any child NVR and the Domain Controller is temporarily broken.
