Event Settings

 

The Event Settings dialog contains all events that can trigger a camera action. Except for the event counter, you can combine the event sensors freely.

Note: Click on the More button to display all options of the dialog.

Event Sensor Description

Event sensor Description
Passive Infrared Detector (PI)

The passive infrared detector registers warm moving objects within the sensor area. The sensor reaches about 10 meters (34 ft.) and has a field of view of ± 15°.

Use the trigger level to define when an event is triggered.

Activate the level meter in the Text and Display Settings dialog and select PIR Detector as source. The level meter helps you find the best possible trigger level for your application.

Video Motion Window (VM)

The video motion sensor reacts to movements in certain image areas, called "video motion windows". You can define one or more independent video motion windows for each image sensor (camera lens).

A video motion window defined for the left image sensor will still be active, even if you only see the image from the right lens of the camera. This means that events detected by the (invisible) image sensor are recognized as well.

Note: When you have activated the Night Camera Level option, only the motion windows of the currently active image sensor are evaluated.

Every line in the definition box (e.g. 0,270,190,100,100,2) represents one window. The image coordinates' origin is the lower left corner of the image.

Hint: If you would like to define a new or additional window, open the Event Settings dialog and follow the instructions in the Graphically Entering Image Areas online help topic.

Format of one line:
Image sensor, pos. x, pos. y, width, height, sensitivity, area[, max. area]

Parameters of one configuration line:

Image sensor 0 = right camera lens
1 = left camera lens
Pos. x Number of pixels from the left edge of the image to the left edge of the window
Pos. y Number of pixels from the lower edge of the image to the lower edge of the window
Width Width of the window
Height Height of the window
Sensitivity Values: 0-99%
The smaller the value, the higher the sensitivity of the video motion sensor.
Area Values: 0-99%
The smaller the value, the smaller the area that needs to change.
The percentage of the window area that needs to change in order to trigger an event.
Max. area Values: 0-99%
The maximum percentage of the window area that is allowed to change in order to trigger an event. This is an optional parameter.
Microphone (MI):

The camera's integrated microphone reacts to noises in the camera's perimeter.

When the trigger level is exceeded, an event is triggered, provided that the noise exceeds the minimum period of time defined.

Activate the level meter in the Text and Display Settings dialog and select Microphone as source. The level meter helps you find the best possible trigger level for your application.

Note: This feature is not available for Basic cameras.
Signal Input (SI):

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

Options:

Off The event is deactivated.
Closed (low) An event occurs, when the switch is closed.
Open (high) An event occurs, when the switch is opened.
Note: This feature is not available for Basic cameras.
Periodic Event (PE): The periodic event is a simple variant of a time-controlled event. Use this event when you intend to trigger events at an interval of less than one minute.
  • Select an interval unit.
  • Set the duration of the interval.
  • The second interval is relevant only when you have activated the Stop Actions (SP) option. Once the stop condition has occurred, images will still be stored while the delay is active.
Time Task (TT)

Time tasks are controlled by tasks that you can create and manage in the Time Tasks dialog.

Activate this option in order to execute time tasks.

User Click (UC)

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

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

Buttons (BT)

Press one or both of the keys on the camera's front labeled R and L to trigger events manually.

Define which camera key or which key combination will trigger an event.

IR Remote Control (IR)

The camera can trigger an event when it recognizes any signal from an IR remote control.

Activate this option to trigger an event for any code received.

Note: This feature is not available for Basic cameras.
IP Receive (RC) The camera can trigger an event when it receives an IP notification via TCP/IP:
  • Set the port at which you expect the notification.
  • Select the type of check:
    String Compare The event is triggered when the received text is identical to the text entered here.
    Regular Expression The event is triggered when the received text matches the regular expression entered here.
  • Enter the text or the regular expression.
Note: This feature is not available for Basic cameras.
COM In (CI) The camera can trigger an event when it receives a message via the serial interface (RS232).
  • Select the type of check:
    String Compare The event is triggered when the received text is identical to the text entered here.
    Regular Expression The event is triggered when the received text matches the regular expression entered here.
  • Enter the text or the regular expression.
Note:

When you perform a binary comparison, you need to enter special characters as hex notations according to the ASCII code.

Example:

Character Hexadecimal notation
? %3F
= %3D
Note: This feature is not available for Basic cameras.
Temperature (TP)

The integrated temperature sensor can trigger an event when the actual temperature is higher or lower than the value entered here:

  • Specify whether the event is to be triggered when the the actual value is higher or lower than the entered value.
  • Enter the temperature that is to trigger the event.
  • Select the unit.
  • Define how often the event is to be triggered:
    First The event is triggered only once, i.e. when the condition is first detected.
    Every The event is triggered every time as long as the condition is true.
Note: This feature is not available for Basic cameras.
Random Event (RD)

The camera can trigger an event at a random point in time.

Enter the number of random events per hour. This value represents the average number of events to be triggered per hour for a longer period.

Note: This feature is not available for Basic cameras.
Event Counter (EC)

The event counter prevents events from being triggered immediately. It only triggers an event when a certain number of events within a defined period of time has been exceeded/reached or not reached, respectively.

Each event image will increase the event counter by one, even if multiple event sensors are active at the time.

The event counter can be used, for example, for monitoring a conveyor belt in a production scenario. When fewer events occur than expected during the defined period of time, a malfunction is recognized and the camera triggers an alarm.

  • Activate the event counter.
  • Define the period of time.
    Values: 1 .. 3600 seconds
  • Enter the number of expected events.
    Values: 1 .. 3600
  • Define the condition to trigger an event:
    More/equal An event is triggered when the expected number of events has been reached or exceeded.
    Less An event is triggered when the expected number of events has not been reached.
  • Define how often the event is to be triggered:
    Every The event is triggered every second as long as the condition is true.
    First The event is triggered only once, i.e. when the condition is first detected.
Note: When the event counter is active, all events are only triggered when the condition defined here occurs.

Store 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.
