Message Events

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

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
Network Message 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 if the received text is identical to the text entered here.
    Regular Expression The event is triggered if the received text matches the regular expression entered here.
  • Enter the text or the regular expression.
  • Select the type of forwarding:

    The camera can forward inbound IP (network) messages to the JPEG Comment and to the Comment queue.

    Off The camera does not forward the comment text.
    Unformatted The camera forwards the comment text without any changes.
    Add date & time The camera adds the date and time to the comment text.
    Add client IP address The camera adds the client's IP address to the comment text.
    Add timestamp and IP address The camera adds date, time and the client's IP address to the comment text.

Note: This feature is not available for Web and Basic models.

Serial COM In 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 if the received text is identical to the text entered here.
    Regular Expression The event is triggered if the received text matches the regular expression entered here.
    Binary Compare The event is triggered if the received text is identical to the binary value entered here.
  • Enter the text or the regular expression.
Note:

If 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

Storing the Configuration

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