Event List

How to add an event:

Right-click the Event list and then click Add or click the icon in the toolbar. The added event has 5 entries that you can edit.

Parameter	Function
Recording tasks Default task	Default setting for recording when event occurs
StartBy	Event is started by ...
StopBy	Event is stopped by ...
OnStart	At the start of the event ... is executed
OnStop	At the stop of the event ... is executed

Right click on one of the entries to open the Actions pop-up window. You can view all actions (default setting) or select the desired thematic group from the list.
Click on the desired action to add it to the selected entry.
Select the added action and configure the action parameters in the setup area.

In the this example, settings were defined for Event 001, however when an event takes place, images are only recorded if settings were defined in the Media Channels tab (see Media Channels Tab).

How to copy an action from PLC simulator:

You can also copy actions and the associated parameters from the PLC simulator and paste them directly into G-Set.

In the PLC simulator, copy the action string.
In G-Set, select respective event entry, e.g. StartBy, and paste the action from the clipboard. The action and the associated parameters are added to the event entry.

You can also add several actions and their respective parameters at once. To do this, paste the action strings from the PLC simulator into a text file and then copy all the actions strings from this file to the clipboard.

Event

When you select the event, the Event tab opens.

You can assign a name and a description to any event.

Assigning a name makes it easier for you to find the desired event again when parameterizing G-Core. Names like "Event 01" quickly become confusing when you have defined more than half a dozen configured events.

The event you created is only activated when you check Active. In this way, you can also predefine events that you only activate when necessary.

Archive Level

Select the desired archive level. The first archive level applies for the permanent record. You can use the default archive levels or may specify your own archive levels for each ring.

More on archive levels and dynamic management of the database can be found in the chapter Database.

A check in the Persistent selection field ensures that the recordings in the rings are kept as long as possible.

Retrigger Mode

After selecting the ring, set the trigger, i.e. specify how the event should react when it is triggered again while it is still activated. There are four choices.

Parameter	Description	Function
Start new instance	Start a new instance
Ignore action	Ignore the action	All set actions are ignored
Retrigger	Trigger again	The event is retriggered. This means that the event configuration runs again.
Order dependent	Dependent on the order	The event settings run in the order of configuration.

Event Run Time

When you enable Event run time, you can set the entire run time of the event in seconds.

Prehistory

The prehistory is the video footage before the start of an event that is associated with the event. There is the static Event prehistory and the Dynamic prehistory .

Static Event Prehistory

The event history is static. It is not triggered by a specific parameter, but always corresponds to the specified duration.

Specify the duration of the Event prehistory in seconds. When an event prehistory is set, the Link prehistory range to event option is enabled with which you have the possibility to link the prehistory to an event.

Dynamic Prehistory

The dynamic prehistory is triggered by an action that has a generic prehistory parameter with it. If the Dynamic prehistory option is enabled, the parameters are used to calculate the dynamic prehistory. If the option is disabled, the parameters are ignored.

Specify the duration of the maximum dynamic prehistory. If the calculated prehistory is longer than the specified duration, the prehistory is truncated to the maximum dynamic prehistory.

The static prehistory and the dynamic prehistory can be active at the same time. In this case, the dynamic prehistory overrides the static event prehistory, if the triggering action has a dynamic prehistory parameter.

For dynamic history, there are two mutually exclusive generic action parameters that can be attached to an action. Either a time or an offset is transported, from which the dynamic prehistory is calculated.

DynamicPrehistoryTimeStamp: A DateTime value that specifies the start time of the dynamic history. It has the same format as the GeneralProcessingTimeStamp, DateFieldA or DateFieldB parameters.
DynamicPrehistoryMilliSeconds: An offset in milliseconds used to calculate the start of the dynamic history. The value is expected to be positive. The DynamicPrehistoryTimeStamp is calculated using the formula [EffectiveEventStartTime - DynamicPrehistoryMilliSeconds].

This dynamic prehistory of an event enables the correct temporal linking of video material with metadata from external systems, regardless of when the data is received by G-Core due to a time offset.

For example, when a package is scanned by a static barcode scanner, there is sometimes a delay between the time of scanning and the G-Core event, so the camera image of the event does not show the scanned package. However, if the event is started by an action that has a dynamic prehistory parameter, the prehistory is dynamically calculated so that the time of scanning is used as the prehistory and is displayed in the camera image of the event.

Time Ranges

By including time ranges in the control scheme, events can be switched on and off. Multiple designations are possible. If none of the time ranges set under time ranges are selected, they are not taken into account.

When Stop on leave valid time range is selected, when the time range expires, the event is stopped.

Example The time range Week goes until 7:30:00 pm. After that, the time range Rest of Time applies. If the event occurs at 7:29:55 pm and the duration is longer than the remaining 5 seconds of the time range, it is stopped with the change to Rest of Time if Stop on Leave Valid Time Range is selected.

Recording Task

Clicking on Recording Task – Default Task opens the settings. This recording task is the default setting for the event [Default Task]. The name for the recording task can therefore not be changed.

You can only assign a name for the recording tasks when you add one or more new recording tasks to the recording task of the event in the event list.

Event Transcoder Settings

The transcoding settings in the area Event -> Recording tasks make it possible to overwrite the transcoding settings of the permanent recording for the event recording when the transcoding is activated in permanent recording.

IMPORTANT: Transcoding cannot be activated for event recording; this is only an option for permanent recording.

The options are:

Option	Function
Override transcoder settings	When this option is activated, the permanent transcoder settings for the recording are ignored and the event transcoding settings for this channel are used.
Quality level	Defines the new quality level of the channel after transcoding.
Fixed max resolution	When this setting is activated, the channel is transcoded in the defined resolution; otherwise the channel retains the resolution defined by the video profile.
Width/Height	Defines the output resolution of the channel after transcoding.

Media Channels Tab

Every Recording Task can be assigned media channels. The record mode and the recording time can be assigned for each of the assigned media channels.

In addition, the default mode can be set for recording and the settings for the activity mode can be specified. You can activate the privacy zones and regions of non-interest as desired.

The default mode settings do not show the values set under Media Channels for the selected channel, instead they show the default settings of the media channel for recording when an event occurs. The profiles configured under QUALITY PROFILES are available.
if activities continue to be registered when an event has occurred (AD), these activities are recorded as specified under Activity Mode. The profiles configured under QUALITY PROFILES are available.
After the recording time expires, all triggered actions are stopped! Exception: You change the settings in the Override Event Run Time tab.

Under Advanced settings, you have three options to control the Record mode for the added :media channel:

Option	Function
Record channel	Record media channel.
Do not record channel	Do not record media channel.
Leave channel in its current state	Leave the media channel in its current state. If this setting is selected, the event is not linked to the video stream event if it is recorded permanently. These events are only recorded in the SQL database (event database). In G-View, you can see a marker in the timeline, but you cannot jump to such events. You always jump to the previous or next event that is set to Record event.
In addition:
Recording time	Setting for the duration of the event in seconds

Note that these settings, as previously described above with respect to the default mode settings, only apply in case of an event and also only for the event for which you use advanced settings. Other events and the default settings of the media channels are not affected by this.
In addition, the settings only make sense when you have created additional Recording Tasks in addition to the Default Task. You can then control the corresponding media channels using the advanced settings.

Override Event Run Time Tab

In this tab you specify the behavior the event triggers at the start of recording:

Override event run time
Disable event run time
Do not change event run time

Events and Sensors

General

The sensors are given special attention when configuring the sensors. Anyone who has worked with other software from Geutebrück should read the following note. The configuration of AD and VMD events and alarms has been considerably simplified.

If AD is used on a media channel with DVSP8 hardware, Sensor Video Alarm (with the sensor type AD) is no longer used, instead the action G-Tect/AD Alarm is used! Accordingly, for the stopping action, Sensor Alarm finished (with the sensor type AD) is longer used, but rather G-Tect/AD Alarm finished is used. The same applies for VMD.
In addition, it is not necessary to activate AD in the VCAEditor for this channel, or even to use the G-Tect service! The analysis of the image changes is performed within the DVSP8 card.
The action Sensor Video Alarm with the sensor type AD and IP-AD, are now only required by IP camera plugins for triggering events by the camera-internal sensors.

In the action list, we find the sensors in the group of actions in video alarms and settings:

There a large number of sensors are available: AD, VMD, VMX, SV and others.

Video Sensor

If you have selected a sensor alarm (in the figure of G-Tect/AD alarm), open the shown configuration dialog by clicking on the sensor alarm.

The dialog provides all sensor messages until "Sensor Alarm Finished". To evaluate the end of a sensor alarm, select (in our example) the action G-Tect/AD alarm finished.

Parameter	Function
Channel	If you select Channel, you can select the media channel for which you want to evaluate the assigned sensors
AD ID	Selection of AD ID
Object direction	Selection of configured direction of movement
Alarm area	Selection of the alarm area

Refer to the settings under Activity Detection (AD) for information on the meaning of the individual configuration options.

Sensor alarm finished

This action is started when a sensor alarm has ended.

If no sensor type is selected, this action evaluates each finished sensor alarm (video or audio/AD or VMD). If no media channel is specified, this applies for all sensors across all channels.

Audio Sensor

If you have selected Sensor Audio Alarm, open the configuration dialog by clicking on Sensor Audio Alarm. Here you can select the media channel whose audio transmission will be evaluated.

If no channel type is selected, this action evaluates each audio sensor alarm (AD or VMD).

To evaluate the end of an audio sensor alarm, use the action Sensor Alarm Finished. See above and under Configuration.

Configuration

You may have already read some about the philosophy of the G-Core events (Understanding events …). Then it will not surprise you that by simply adding a sensor alarm action, an event configuration has been performed.

How Does This Work?

If sensor systems (AD, VMD and/or VMX) were configured, then sensor alarm messages are also sent when an alarm occurs.

If no specific media channel is selected, all channels are evaluated for the event, and similarly if no sensor type is selected, all sensor types are used for the event.

This means that when an action is added to the event configuration, the widest possible scope is used for the evaluation of the sensor alarms: That is: the evaluation of all (video) sensor messages! (The same applies for audio).

In the following configuration, only AD alarms are used for the event, but this applies for all media channels!

Alarm

In the Alarm tab you can assign a name to the alarm and activate the alarm (Active checkmark).

Settings Tab

Below you will see a slider which allows you to assign the alarm one of three priorities:

Red	= highest priority
Orange	= medium priority
Yellow	= low priority

In G-View under Options you can configure the display and the behavior of the three alarm priorities.

If you have also configured alarm scenes there, instead of the default setting (Default Alarm Scene is activated), you can also select a different display configuration.

Now assign the triggering event to the alarm by selecting the event from the list of configured events.

And if you want an alarm text, which will be displayed when the alarm occurs, enter this text under Alarm Message.

If you activate the alarm for a configured event, the event is provided with the background color of the alarm priority and the icon changes from event to alarm.

Media Channels Tab

If you enter one or more media channels in the Media Channels tab, you can specify the Play Mode for the media channel.

Play Mode	Function
Show first alarm picture only	Only the first alarm picture (still image) is shown in the configured alarm viewer
Live replay	The live video is activated in the configured alarm viewer
Replay event pictures	The configured images of the event video recording are shown once in the alarm viewer
Continuous event replay in a loop	The configured images of the event video recording are shown in a loop in the alarm viewer

If you tick Play Audio, the associated sound will be transmitted.

Include Prehistory ensures that the additional prehistory is included.

Alarm Push Function Tab

Make settings in the Alarm Push Function tab when you want to forward the alarm to one or more G-View workstations in the network.

To do so, under Alarm Push Function Target click on the add icon to create a new target. Then apply the settings you configured in the selection menu under APF Connections. You can also create alternative connections.
