8 Advanced Features
In this paragraph are described some advanced features supported by the device, which might be
requirement for different use cases.
8.1 Geofencing
Figure 8: Geofencing
Geofencing (an electronic safety fence) provides the opportunity to set a geographic square around a
defined location. Here you can set different scenarios like “leaving the area” or “entering the area”
and transmit an event to the control centre. With the SBC-AVL you can monitor 50 geofence areas
which can also be combined to create larger areas and build up a complex protection zone.Every
geofence area is given an Area ID, a center (defined by its longitude and latitude) and a height and
width (from the center not completely across) in meters.
8.2 Roaming alternative configuration
The device is able to detect a GSM roaming status and swap automatically to an alternative setup for
roaming (this alternative setup has to be previously configured). This allows optimizing the data
traffic and reducing the communication costs.
8.3 Input alternative configuration
The device is autonomously able to handle an alternative setup when a specific input is triggered
(this alternative setup has to be previously configured). This can support features like “panic button”.
8.4 Device Watchdogs
The SBC-AVL has different integrated watchdogs. They automatically check the functions of the
device and generate resets as soon as they recognise any malfunction. Malfunction could occur due
to internal problems of the device, problems related to the GSM connection, problems with the GPS
reception and many more.
This watchdog concept ensures that the SBC-AVL can automatically return to stable operation if
necessary. Control of the watchdogs by the user is not necessary.
If the watchdog has to restart the device it may happen that some of the position messages and
respectively events are not logged and as a result they are not transmitted to the tracking server.
