Network Distribution of Messages

Open the Network Distribution of Messages dialog to configure the message transfer between cameras. Currently, you can use up to 32 cameras for one physical network for such a message system. This restriction does not apply when using the Broadcast distributor type.

General Interface Setup

Parameter

Description

Network

Activate/deactivate the transfer of messages between cameras over the network.

Password

A password (symmetrical key) of at least six characters, which is used to encrypt the transferred messages.

Distributor type

Two message distribution types are available:

  • Broadcast does not guarantee that the messages are actually received by the recipients ("Fire And Forget"). Transmission errors are not corrected by resending the messages. Messages are not sent to the recipients in a specific order. Note that there is not limitation regarding the number of message system users in a network.

  • Multicast reliably guarantees that the messages are actually received by all recipients in the same order. Transmission errors are corrected by resending the messages. A message is distributed to either all recipients or − if transmission errors are persistent − to no one at all. Note that number of message system recipients in a network is limited to 32.

Settings Depending on the Distributor Type

Depending on the distributor type chosen (Multicast, Broadcast, see above), you can set different options.

Distributor type

Description

Multicast

  • Multicast Port: The messages are transferred using UDP Unicast and Multicast on the specified port and the preceding port. If you want to run several independent message systems on your network, assign different ports to the systems. Make sure that you use ports that are different by at least two numbers.

Broadcast

  • Broadcast Port: The messages are transferred using UDP Broadcast on the specified port. If you want to run several independent message systems on your network, assign different ports to the systems.

  • Recurrence: This parameter specifies how often in total the message will be resent. Many resends increase the probability that the message is actually received, but they also create heavier network load.

  • Poll Frequency: This parameter specifies how often per second the messages will be sent. A higher frequency reduces latency, but creates heavier network load.

  • Max. Time Difference: Maximum difference between the message timestamp and the system time. Messages with a greater difference are discarded. It is highly recommended to synchronize the system time of all message system components using NTP (in the Date and Time dialog).


Konfiguration sichern

Klicken Sie auf Setzen, um die Einstellungen zu aktivieren und bis zum nächsten Neustart der Kamera zu sichern.

Klicken Sie auf Voreinstellung, um diesen Dialog auf die werkseitigen Voreinstellungen zurückzusetzen (dieser Button wird nicht in allen Dialogen angezeigt).

Klicken Sie auf Wiederherstellen, um alle Änderungen seit dem letzten permanenten Speichern der Konfiguration zu verwerfen.

Beenden Sie den Dialog durch Klick auf Schließen. Hierbei wird geprüft, ob Änderungen der Gesamtkonfiguration vorliegen. Ist dies der Fall, werden Sie gefragt, ob die Gesamtkonfiguration dauerhaft gesichert werden soll.
