— one of the functions found in recorders with a GPS module (see the relevant paragraph). The GPS tracker allows the device to work in the beacon mode, constantly transmitting data about the location of the car to one or another addressee — for example, taxi service dispatchers, a cargo transportation customer, etc. Such beacons are also sold as separate devices, but it is easier (and sometimes cheaper) to buy and install a recorder with this function. Anyway, it should be taken into account that a 3G / 4G modem is usually used for data transfer (see below) — so to use the tracker you will have to buy a SIM card and regularly pay for mobile communications.
