FMC920 Manual Geofence Settings

Geofence Basics

The Teltonika FMC920 device supports up to 50 configurable geofence zones. These zones allow for the generation of events when a defined geofence zone border is crossed.

A Frame Border is an additional boundary around the geofence zone. Its purpose is to prevent false events that can occur when a tracked object stops near the border, causing GNSS errors to register records both inside and outside the defined area. An event is triggered only when both the primary geofence border and the frame border are crossed.

Visual representation indicates that a blue track signifies entry into the geofence area, while a red track signifies it is not within the area.

The Shape of a geofence zone can be defined by the user as either a rectangle or a circle.

Geofence events are categorized into priority levels: Low, High, or Panic. These levels dictate the urgency and priority of the event information transmitted to the server. For more details on priorities, refer to the I/O settings section.

Event Generation and Record Handling

The Generate Event setting determines the specific condition under which a record will be created.

Eventual Records control the visibility of scenario status values:

• When disabled: The status value will be present in every AVL record.
• When enabled: The status value will be appended only to specific eventual records, reducing data volume for non-critical events.

Overspeeding Configuration within Geofences

The FMC920 allows for the configuration of Overspeeding scenarios independently for each geozone. Regular overspeeding configurations and geozone-specific overspeeding functions operate separately.

However, if digital output control is enabled in a regular overspeeding scenario, the geozone overspeeding scenario can also influence it. Specifically, if the device is located within one or more geozones and overspeeding is detected in any of those zones, the digital output will activate. This output will only deactivate when overspeeding is no longer detected in any active zone.

Geofence Coordinate and Shape Parameters

The definition of geofence zones requires specific coordinate inputs:

For Rectangular Zones:

• X1: Sets the X-coordinate (longitude) for the bottom-left corner of the geofence zone.
• Y1: Sets the Y-coordinate (latitude) for the bottom-left corner of the geofence zone.
• X2: Sets the X-coordinate (longitude) for the upper-right corner of the geofence zone.
• Y2: Sets the Y-coordinate (latitude) for the upper-right corner of the geofence zone.

For Circular Zones:

• X1: Sets the X-coordinate (longitude) for the center of the circular zone.
• Y1: Sets the Y-coordinate (latitude) for the center of the circular zone.
• R: Sets the radius of the circular zone.

Teltonika Configurator Interface

The Teltonika Configurator software facilitates the setup of these geofence parameters. The interface typically includes:
