9 The DETEXI Reliability System minimizes the risk of system failure and
associated down-time.
2. System Health Monitoring
In the default setup the DETEXI NVR is working in an unattended mode, this means it is up to the local
administrator to check the status of the programs and related hardware manually. However, in most cases
a PC Server accommodating the DETEXI software is in a remote location with no local human interaction,
therefore a designated person or persons should be aware of the DETEXI NVR status at any given time.
You may not need the recorded video for weeks or even months, but if something happened (camera
failure, power failure, network failure etc.) during that time it is possible that the NVR does not have some
or any recorded video at all and the required evidence may be lost.
There are several areas that should be checked to insure that you have a healthy and functioning system:
• Is the NVR running at all (power is OFF or ON)
• Are all selected NVR services running
• Are all cameras with an active schedule functioning and being recorded
• Is there enough space to make a recording
• Are there enough system resources to make a recording
• Is the NVR Domain Controller network and all it’s child NVRs healthy and running
To address these issues the Reliability System is embedded into the DETEXI Network Video
Management software. To monitor the health of the NVR services you need to assign a predefined task
that will be executed in a case of failure to each service you wish to monitor. Predefined tasks to be
executed on check status/ health consist of one or more actions/notifications:
• Network Client notification
• E-mail notification
• Phone notification
• Speak notification
• Execute program action
