The LMU-330 high-value tracking unit from CalAmp features a small footprint superior GPS performance, an optional internal back-up battery, ultra low power sleep modes, optional 3-axis accelerometer for motion sense, and up to two Inputs/two Outputs (I/O). The LMU-330 is a complete vehicle tracking and communications device incorporating next-generation, supersensitive GPS technology on cellular networks for installation in any 12/24 volt mobile vehicle. Superior internal antennas for both cellular and GPS eliminate the need for wired antennas and make the LMU-330 mountable virtually anywhere in the vehicle for easy, inexpensive installations. Messages are transported across the cellular network using enhanced SMS or UDP messaging providing a reliable communications link between the device and your application servers. The LMU-330 is designed to dramatically reduce cost, power and size while providing excellent field reliability.


The LMU-330 employs CalAmp’s advanced industry leading on-board alert engine, PEG™ (Programmable Event Generator) to monitor external conditions and support customer-defined exception-based rules to meet your application requirements. PEG monitors the vehicle environment and responds instantaneously to pre-defined threshold conditions related to time, date, motion, location, geo-zone, input and other event combinations. This behavior can be programmed by CalAmp before shipment, at a customer’s facility, or over-the-air once the unit has been fielded.


The LMU-330 leverages CalAmp’s management and maintenance system, PULS™ (Programming, Updates, and Logistics System), for over-the-air configuration parameters, PEG rules, and firmware. This out-of-the-box hands free configuration and automatic post-installation upgrades can monitor unit health status across your customers’ fleets to Identify issues before they become expensive problems.
