we've just launched a self contained, waterprrof, rugged, small, security tracking device called Trac-It, It uses motion sensors, GPS, GPRS and RF technology.
It is Thatcham approved.
A user can have multiple 'assets', which can be varied, (boats, cars, trucks, whatever), all visible as personalised (named) icons on a web portal.
One trac-It phone number is stored within the user's mobile, where all of the communications from all of the assets is sent, making it very simple.
Multiple email / mobile numbers can be added (per differenet asset), within the portal.
All sorts of information is transmitted back to the user, battery life, movement detection, and the Trac-It goes into 'live track mode' (every 60 secs) when these alerts are raised. Then all of those email / mobile numbers are alerted too.
If an alert is raised, the user (and those that are included in the text / email list), can aske the Trac-It uit where it is, and it's exact position (lat long ), will appear through a text, with location viewable on a map.
Also alerted (an option) is an approved secure monitoring service, who will liase with the authorities to get your asset back in the event of a theft.
the real beauty is that the user can self manage the trac-It devices, and act accordingly.
You can set each Trac-It device to act as a journey monitoring device, as each journey (every 60 secs), can be logged displaying on a map, with speed indicated too.
