Task Triggers

In the NVR a trigger is a set of criteria that, when met, starts the execution of a predefined task. In order to get advantage of receiving a notification and/or executing action defined in the task this task should be assigned to a specific alarm/event in the NVR Control Center.

The following alarms/events can be raised in the NVR and start execution of assigned tasks —

System Health Alarms/Events

General

NVR Status Task —(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.
NVR Service Health Status — when any of the individual NVR Services encounter problems, this event is raised.

NVR Storage Errors

Archive Storage Writing Error — when video cannot be stored to the designated archive path due to a writing error, such as insufficient permissions to write to the drive or if the path is invalid, this event is raised.
Archive Storage Drive Limit Reached — when the drive limit defined in the If free space is less than [XX] MB parameter is reached, and the Stop Saving option is set, this event is raised. This alarm automatically causes the recording service to stop. User intervention is required to restart the service when appropriate resources are available.

IP-Device Status

Check Alive service task — the Check Status Task can be triggered if the IP-device fails to answer on the Check Alive service request.
Recovery Procedure tasks — when NVR loses connection to a camera it is scheduled to record, it enters into a recovery procedure. Tasks can be executed at different points within the procedure. Task on First Error can be triggered when NVR first loses connection; Task on Recovery Procedure Failure — initiates if all the attempts of recovery procedure have failed; Task on Restore initiates in case the IP-device comes back online.

NVR Network (Domain) Alarms

When NVR does not respond — the task should be setup for each child NVR in the NVR network (domain) to be aware weather a child NVRs are alive and properly respond to the NVR Domain Controller.

General User Login/Logout

Login/Logout Task — when any user logs in or logs out, the event is raised with information indicating the user and the action (login/logout).

Specific User Login/Logout

Login Task — this event indicates that a specific user has logged in. Used instead of or along with the general login/logout event, allows different tasks to be assigned individually to users of interest.
Logout Task — this event indicates that a specific user has logged out. Used instead of or along with the general login/logout event, allows different tasks to be assigned individually to users of interest.

IP-Device Alarms/Events

IP-Device Status — System Health Monitoring Alarms/Events

Check Alive service task — the Check Status Task can be triggered if the IP-device fails to answer on the Check Alive service request.
Recovery Procedure tasks — when NVR loses connection to an IP-device it is scheduled to record, it enters into a recovery procedure. Tasks can be executed at different points within the procedure. Task on First Error can be triggered when NVR first loses connection; Task on Recovery Procedure Failure — initiates if all the attempts of recovery procedure have failed; Task on Restore initiates in case the IP-device comes back online.

IP-Device FTP Alarm

FTP Alarm— in some wireless configurations, and other environments where constant streaming is not possible, video can be uploaded via FTP based on decision making within the IP-device. When video is uploaded to the DETEXI NVR FTP Server, the video is merged into the archives as alarm video, and this event is raised.

IP-Device Alarm on Motion

Input Alarm — if an IP-device supports external I/O, the Check Alarm (IO Listener) service can monitor the status of the camera’s inputs. This event is raised when an IP-device’s defined input is in an active (non-normal) state. A separate event is raised for each IP-device input that has this feature enabled.
Soft Motion Alarm — when motion detection is enabled in the IP-device recording schedule, an event is raised each time motion is detected on an IP-device by the DETEXI software. A separate event is raised for each IP-device recording schedule if Alarm on Motion is configured.

User Triggered Task

User Triggered Task (from Remote Client) — task execution can be added to a user’s permissions, by assigning users the specific tasks they are allowed to trigger manually from the remote DETEXI Client.

Each individual event can only have one task assigned to it.
Any task can include one or more actions/notifications, allowing for multiple things to happen when a single alarm or event is raised.
An event can also have a composite task assigned to it. Any composite task consists of several predefined tasks of the user’s choice. And what is more, a composite task has embedded schedule.
