DETEXI NVR 49 - 169
NVR; and Domain Controller connections — connections between the DETEXI NVR Domain Controller and
child NVRs.
The DETEXI software consists of different modules/services — Monitor, Camera Server, Recorder, FTP
Server, Check Drive, Check Alive, Check Alarm, Tour, Get Shots, Port Mapper, Port Listener, Alarm
Server, Remote Server, Socket Server. Any of them could fail due to unforeseen events and therefore must
be monitored and controlled.
Several areas should be checked constantly 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 components 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
2. Task Execution Engine
The DETEXI IP-Surveillance reliability checking is based on the Task Execution Engine. If something
happens to the system, hardware or one of the DETEXI NVR components, certain task assigned to this
event is executed.
What if something happens to the Task Execution Engine by itself?
The obvious conclusion is — you will never have any task executed at all and you will never know that
something is wrong with the DETEXI NVR. To solve this issue we have developed a special NVR Status
Task which (if assigned) is executed once a day at a time you can predefine by yourself. If this task HAS
NOT BEEN executed at that time it means you have to check the system.
Tasks to be executed on
check status/health consist of predefined tasks — network client notification,
E-mail notification, phone notification, speak notification or Execute Program action. Read more in the
Event Management section.
9 Alarm Server service responsible for raising alarms via the text-to-speech engine,
telephone, and e-mail must be running and configured in order to send alert
notifications.
9 From our point of view it is most likely user will initiate the E-mail notification task
or Execute Program action.
9 Before using the e-mail notifications task the necessary settings — SMTP and e-
mail account settings must be setup in the Alarm Server.
9 The Execute Program action allows user to execute any external program and is
limited only by your imagination and the resources required to develop it.
