goopass units are very reliable ... we have plenty of them on the systems,
we have some minor problems regarding connectivity with this devices ... and due the fact the hardware is compatible trough smartpipe only the historical data will not be handled by gpsgate.
but the value is great for the price.
the Intellitrack units are better in terms of gpsgate compatiblity as GG does fully support this hardware with all its features.
in europe and Us this hardware running by about 190 USD .. so the price is okay compared with the functionality, quality and reliability you got.
TR-151 is worlds away from quality and service friendlyness from the hardware mentioned above.
we using Goopass AVL 900 for private vehicles (because they have a microphone option where you can listen into the car), extremly strong casing and can be ordered with direct power connection (you will need to order a bunch of them to get this modification)
by default they are powered by mini-usb.
intellitrac for anything needs security, memory, reliability and something you can trust on.
Backups are for WIMPS!
