Signal Events

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

Avoiding False Alarms

Meta Events

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.


General Settings

Option 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.


Storing the Configuration

Click on the Set button to activate your settings and to save them until the next reboot of the camera.

Click on the Factory button to load the factory defaults for this dialog (this button may not be present in all dialogs).

Click on the Restore button to undo your most recent changes that have not been stored in the camera permanently.

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.
