Solution description

One of the more advanced features of GPS trackers is the ability to create Geofence scenarios in a real-time with triggered alerts. Geofences are designated areas or zones that can be defined on a map or as a distance from the specific location. The feature may help to comply with some pandemic lockdown measures and greatly benefit private car owners, families, corporate fleet managers and business owners. All Teltonika GPS tracker models have Geofence as a standard feature.

What you need for a solution?

  • Geofence solution is supported by all Teltonika devices. To show this scenario, we will be using the FMM130 model.
  • The SIM card in order to receive data to your server.
  • Teltonika Configurator to make the configurations for your Teltonika device.
  • FOTA WEB to send the configurations to your device remotely.

Installation

Since Geofence can be used in all of Teltonika devices, it is important to follow your specific device mounting recommendations. This is because if you were to install the tracker following the instructions of a different one, your device may not work properly in the end. Also, we offer a wide range of trackers that have different connectors, some of the devices we offer are "Plug and Track" (devices that have OBD-II connectors), other may demand more wiring work to be done. The list of all Teltonika Fleet Management devices can be found here.

Configuration

1. Prerequisites:

1.1. Read through First start guide

1.2. Understanding what manual Geofence has to offer.

2. Configuration of Manual Geofence feature

Parameter ID – Parameter name GPRS settings:


  • 2001 – APN
  • 2002 – APN username (if there are no APN username, empty field should be left)
  • 2003 – APN password (if there are no APN password, empty field should be left)






Server settings:

  • 2004 – Domain
  • 2005 – Port
  • 2006 – Data sending protocol (0 – TCP, 1 – UDP)




After successful GPRS/SERVER settings configuration, FMM130 device will synchronize time and update records to the configured server. Time intervals and default I/O elements can be changed by using Teltonika Configurator or SMS parameters.






Manual Geofence settings:

  • 20100 - Feature priority (0 - Disable, 1 - Low, 2 - High, 3 - Panic)
  • 20101 - Generate Event (0 - No Event, 1 - On Exit, 2 - On Entrance, 3 - On Both)
  • 20102 - Eventual Records (0 - Disable, 1 - Enable)


  • 20103 - Frame Border (m)
  • 20104 - Shape Type (0 - Circle, 1 - Rectangle)
  • 20105 - Radius (m)
  • 20106 - Coordinate Y1
  • 20107 - Coordinate X1
  • 20108 - Coordinate Y2
  • 20109 - Coordinate X2


  • 20110 - Overspeeding (0 - Disable, 1 - Enable)
  • 20111 - Max allowed speed (km/h)


  • 7025 - Phone Number
  • 8025 - SMS Text







Note: Radius is only calculated if the chosen Shape Type is a Circle. In this example, Radius cannot be seen since the shape chosen is the Rectangle. Also, Latitude Y2 and Longitude X2 are only used when Rectangle is the chosen shape.

It is also important to mention that the map in the Manual Geofence function section has a few features as well if you wish to make some adjustments using the interface:

Manual Geofence also has a nifty feature that allows the user to draw their wanted Geofence using only the mouse. There are 4 buttons that make this feature into reality.

First two are for drawing a circle or a rectangle. Simply press on the button, drag your mouse for the area you want the Geofence to be located and release. The Configurator will automatically calculate the size.

The 3rd button is for deleting the Geofence which is currently chosen.

The last button on the interface is used to zoom in on all of the available geozones.




Quickstart: From default configuration to Geofence crossing detection in two SMS:

"  setparam 2001:APN;2002:APN_username;2003:APN_password;2004:Domain;2005:Port;2006:0"
"  setparam 20100:2;20101:2;20104:1;20106:latitudeY1;20107:longitudeX1;20108:latitudeY2;20109:longitudeX2"

This SMS will set up your device to report Geofence Crossing Detection scenario to the server.

Note: We're sending two instead of one configuration messages since one SMS can contain up to 160 characters. For this scenario, we exceed the maximum allowed character amount. Therefore, we split the message into two.

Demonstration in platform

TAVL: Open TAVL → select client → Track. By choosing a certain date frame for the device that you're watching, you can see the events that are generated when the Geofence is crossed (depending on what was chosen on the Configurator: On entry, on exit, on both).

Wialon: Open WIALON → open messages → push unit ( select your device) → choose the date from which to which to show the records → select message (data messages) → push execute button and you will see all information.
