Signal Events

The Signal Events dialog contains all event sensors that can trigger a camera action based on incoming signals.

Using Meta Events to Avoid False Alarms

In order to filter events, the camera provides an Event Logic: This dialog allows linking events to create logic events only if the linked events occur in a certain sequence and within the specified time frame. Another possibility to filter events is the Event Counter: It creates an event only if a certain number of events occurs within the specified time frame.

Description

Event Dead Time

The event dead time defines a period of time (0..3600 s) after an event, during which no new events from the same profile are recognized.

By defining an event dead time you can avoid, for example, that a complex action (person walks through the active image area) triggers multiple events.

Description of Event Sensor Types

Event Sensor Type

Description

Signal Input

The camera's signal inputs can trigger events. For example, you can connect the door bell with the signal input so that an event is triggered when the bell is rung.

Options:

Open (high)

Triggers an event if the contact is open.

Closed (low)

Triggers an event if the contact is closed.

Rising (low to high)

Triggers an event if the contact is being opened (rising signal flank).

Falling (high to low)

Triggers an event if the contact is being closed (falling signal flank).

Change (Rising or Falling)

Triggers an event if the state of the contact changes (rising or falling signal flank).

De-Bounce Time

This interval prevents the signal input from switching to fast (e.g. if the bell button is being pressed in quick succession).

Note

This event sensor type contains the keys on the camera body, as well as those on connected expansion hardware. The exact inputs available depend on the camera and expansion hardware you are using.

Signal Output

The camera's signal outputs can trigger events. A door station can activate the light using several different methods, for example. This event allows reacting to the fact that the lights are switched on, without having to actually know which command switched on the lights.

Options:

Open (high)

Triggers an event if the contact is open.

Closed (low)

Triggers an event if the contact is closed.

Rising (low to high)

Triggers an event if the contact is being opened (rising signal flank).

Falling (high to low)

Triggers an event if the contact is being closed (falling signal flank).

Change (Rising or Falling)

Triggers an event if the state of the contact changes (rising or falling signal flank).

De-Bounce Time

This interval prevents the signal input/output from switching to fast (e.g. if the light button is being pressed several times in quick succession).

Note

The exact outputs that are available depend on the camera and its attached modules.

User Click (UC)

This will allow triggering events manually by clicking on the UC Event softbutton.

Activate this option if the camera should react to these events.

Memorizzazione della configurazione

Fare clic sul pulsante Imposta per attivare le impostazioni e salvarle fino al prossimo riavvio della videocamera.

Fare clic sul pulsante Default per caricare i valori di default di questa finestra di dialogo (opzione non presente in tutte le finestre di dialogo).

Fare clic sul pulsante Ripristina per annullare le modifiche più recenti che non sono state memorizzate in modo permanente nella videocamera.

Fare clic sul pulsante Chiudi per chiudere la finestra di dialogo. Durante la chiusura della finestra di dialogo il sistema verifica eventuali modifiche nella configurazione. Se le rileva chiede di memorizzare in modo permanente l'intera configurazione.
