Event logic

The Event Logic dialog provides two independent logic events (EL and EL2) that provide means for testing the order of occurrence of the selected events. Using the event logic, the camera can detect direction of motion or other combinations of events, thus reducing false alarms as much as possible

Note:	If the logic events EL and EL2 should be used for filtering actions and messages, you should not use any "regular" events (Event Settings dialog), but only the logic events EL or EL2, respectively.

General Settings

Event Dead Time

The Event Dead Time will prevent new events from triggering after an event has been detected. This deadtime only governs the two logical events EL and EL2 defined on this dialog.

Defining Logical Events

The event logic provides two independent logic events (EL and EL2), each of which can be tested for the order of occurrence of the selected events. The event is triggered if one of the events selected in Event List A and one of the events selected in Event List B occur within the specified Maximum Time Window. The order of occurrence is optional; it does not necessarily be part of the evaluation (see below).

Note:	Events in the event lists that are displayed gray and in brackets are deactivated; if you intend to use them, configure the desired events in the Event Settings dialog.

The EL event (or EL2, respectively) will only be triggered if the interval set in Minimum Delay passes between the occurrence of events specified in the two Event Lists.

When used in conjunction with the VM and VM2 video motion detectors or other suitable sensors, the camera can start actions, send messages and record images depending on the direction of motion, for example.

Parameter

Description

Event Logic Enable

Activate the event logic if you would like to trigger alarms and recording using this event. The event logic checks if one of the events selected in Event List A and one of the events selected in Event List B occur with the specified Order of Occurrence.

Maximum Time Window

Set the maximum length of the time window in which one of the events selected in the second event list has to occur.
Values: 1 second to 15 minutes

Event List A

Highlight the desired events in the Event List. Hold the [Ctrl] key pressed to select more than one event.

All selected events are AND-linked, i.e. only one of the selected events has to occur for an event list to become true.

Order of Occurrence

Set the desired order in which one of the events selected in Event List A and one of the events selected in Event List B should occur to trigger the event:

A -> B	Triggers the logical event only if one of the events selected in Event List A occurs first and (after the Minimum Delay has passed) one of the events selected in Event List B occurs.
A <-> B	Triggers the logical event (regardless of the order in which the events occur) if one of the events selected in an event list occurs and (after the Minimum Delay has passed) one of the events selected in the other event list occurs.

Minimum Delay

Set the minimum delay, which has to pass before one of the events selected in the second event list is accepted.
Values: 0 to 20 seconds

Event List B

Highlight the desired events in the Event List. Hold the [Ctrl] key pressed to select more than one event.

All selected events are AND-linked, i.e. only one of the selected events has to occur for an event list to become true.

Storing the Configuration

Click on the Set button to activate your settings and to save them until the camera is rebooted.

Click on the Close button to close the dialog. While closing the dialog, the system checks the entire configuration for changes. If changes are detected, you will be asked if you would like to store the entire configuration permanently.
