ZOI's
or Zones of Interest, are places that you can put on the map that you
wish to "keep an eye on". For example, depots, customer sites
or even the cafe round the corner!
When
a vehicle enters or leaves one of these ZOI's an alert can be raised
at your PC. Using this information you can perhaps get an extra delivery
or service call completed thereby increasing your revenues.
ZOI's
can be a circle, rectangle or polygon making it easy to exactly control the area you are interested in with great ease.
