accelerometer: A device that measures proper acceleration (g-force). Most recent models of GPS/AVL boxes installed on vehicles have an accelerometer. The accelerometer makes it possible to measure atypical vehicle operation such as harsh braking, acceleration, and turning. It can also be used to determine when a vehicle has been involved in a collision.
alert: Also called a notification. A message notifying users of certain asset activity. You can configure alerts/notifications to be sent as an email or SMS (text) message.
antenna (cellular and GPS): A GPS box (such as an LMU) typically connects to an external antenna that is dual mode. This is a satellite-receiving antenna and a cellular transmitter/receiver. Some LMUs have an internal antenna.
application programming interface (API): A means of exchanging data with other applications.
asset: The equipment you are tracking. Usually, this will mean vehicle, but it also could be farm equipment, cargo containers — anything of value to you that could be in motion and therefore trackable.
asset tracker: An ATU (asset tracking unit) or TTU (trailer tracking unit); these tracking devices collect location and operational data and transmit that data to CalAmp. They are used to protect assets in the event of theft; CalAmp can locate a stolen vehicle so that the authorities can retrieve it.
automatic vehicle location (AVL): The capability to locate a GPS-equipped vehicle.
boundary: A geographic area used to measure asset activity.
CalAmp Tag: A smart proximity sensor you can attach to equipment that is often associated to a particular asset — the goal being making sure that all the right tools are on the right vehicle. If a tagged item is left behind at a worksite or otherwise lost, CalAmp can identify its last-known location (based on the GPS data from either its assigned vehicle's LMU or just the closest vehicle's device and when the tag was last in proximity to it) and alert you so that you can find it quickly.
engine diagnostics (ED): An assessment of a vehicle's engine, used in particular to identify why an engine is not functioning properly; CalAmp's ED equipment can receive and integrate the data transmitted by a vehicle so that diagnostic codes can be read remotely when they are generated.
ESN (electronic serial number): A unique numeric identifier for a GPS device.
events: Calculated, timed, or triggered inputs that are transmitted to the CalAmp database. Events provide specific information about asset activity and can be used to trigger alerts.
excessive engine idle time: Idling time is calculated based on the ignition state of a vehicle combined with information about its movement. CalAmp keeps track of idling occurrences so that you can monitor excessive idling, and subsequent gasoline wasted, in your fleet.
geofence: A specific location you can use to monitor asset activity. Geofences can be used for job sites, geographic areas where vehicle activity is prohibited, where community complaints are an issue, where you particularly need to monitor the speed of your vehicles — basically, for any region pertinent to your drivers or organization.
geofence event: When an asset enters or exits the boundary surrounding one of your designated geofences (areas of interest to your organization, such as job sites or vehicle yards).
global positioning system (GPS): A system of satellites that transmits information and locates devices that are equipped to send and receive GPS data.
group: A set of assets, users, drivers, and other entities. In the CalAmp application, you can organize your assets in a flexible configuration of groups that reflects how your fleet operates, and you can use the groups to determine the level of visibility and access your users have, like accounts and subaccounts. Users will only be able to see assets within the group they are assigned to (and its subgroups).
Group Chooser: in the banner at the top of the screen. Clicking either the icon or group name opens a window that enables you to select any group of assets you have access to (which will be the group you are assigned to, plus its subgroups). All screens you launch thereafter will display the chosen group's data by default.
harsh events: Driving events that are extreme, indicating driver behavior that could adversely affect the efficient and safe operation of your fleet. LMUs provisioned with an accelerometer measure vehicle movement and sudden changes and thus can report events deemed "harsh." The following are the current industry-defined harsh events:
- Harsh acceleration: 250 cm/s/s for 1.5 seconds
- Harsh braking: 300 cm/s/s for 1.5 seconds
- Harsh turning: 400 cm/s/s for 2 seconds
LMU (location messaging unit): A GPS device installed on the vehicles that communicates asset data to the CalAmp database.
machine-to-machine (M2M): Technologies that allow both wireless and wired systems to communicate with other devices of the same type.
map view: An area of the CalAmp map you have saved previously so that you can focus in on it quickly and easily in the future.
notification: Also called an alert. A message notifying users of certain asset activity. You can configure alerts/notifications to be sent as an email or SMS (text) message.
operator: Also called driver. An individual who drives one or more of your vehicles. If there is a vehicle asset an operator drives consistently, you can associate them to it.
report: Detailed information regarding a variety of asset/driver activities and other data. See the Reports folder for more information.
role: The position a user has in your organization. Roles determine the software privileges your users have. The CalAmp application comes prepackaged with three basic roles — Admin, Demo, and User — but new ones can be created and customized as needed.
route: In the CalAmp application, this isn't defined as you might think it would be; it's not a path a vehicle is assigned to follow (a specific itinerary of stops along a course); rather, a CalAmp route is an attribute you can define to use as a filter (such as snow routes in a certain area).
schedule: A designated portion of the day you can apply to an alert/notification so that it will be triggered only during those hours — for example, you can create a schedule from 9 a.m. to 5 p.m. and associate it with an excessive idling alert if you want to be notified about overidling only during the workday. Assets and drivers can be assigned schedules as well.
scheduled reports: In the CalAmp application, you can set parameters for the generation of reports on a scheduled basis.
scripts (firmware): The programming used to configure the GPS tracking units.
sensor: A device that detects a physical property and responds by taking a specific action — for example, a GPS sensor picks up a signal and relays that information in the form of directions.
tap points: Connections to inputs on a vehicle in order to collect information about vehicle activity, such as sand/salt spreader events.
telematics: The collection of locational data via GPS tracking devices.
transceiver: The device within an LMU that transmits and receives information via the cellular network in order to log activity to the CalAmp database.
wire harness: The wiring that connects an LMU to a vehicle for power, ignition, and other inputs.
