GPS Terms
| Term | Definition |
| # of Satellites | Number of satellites used to determine GPS monitoring device location |
| Fix | The GPS device’s geographical location on a map at (a) given point(s) in time |
| Speed | The rate at which the GPS monitoring device is moving |
| Direction | The geographical orientation of the GPS device as it is moving |
| CSQ | Signal Strength Quality – The strength of the signal experienced by the GPS monitoring device – equivalent to the number of “bars” on a cell phone |
| Point, RMC | A single location point from the bracelet |
| Lat / Long | The global latitude and longitude address of a given location point |
| CTP | Cell Tower Point – A location point derived by calculating the GPS device’s proximity to the three closest cellular wireless network towers. Also referred to as “triangulation.” Used when satellite-derived location is unavailable due to unfavorable environmental conditions. |
Application Basics
| Term | Definition |
| SCRAMNET GPS | SCRAM Systems’ monitoring system application |
| GPS Analytics | Reports in the application that consolidates thousands of GPS points into a meaningful calendar of client’s travel and stop patterns. |
| Alerts | A generic term that refers to events that can potentially generate notifications. This term is often used interchangeably with events. |
| Events | A generic term that is used to describe any bracelet-related occurrence that can be displayed in the Event Details pop-up window. Events can be informational, such and plugs and unplugs, or they can represent a critical incident that needs immediate attention. |
| Messages | Refers to the actual data that is sent by a bracelet to the system. Messages include a variety of information including location, battery status, bracelet status, and event information. |
| Notifications | Emails and/or text messages that are sent to recipients when designated events are generated. |
| Onboard vs. On-Server Zones | Onboard zones are stored on the SCRAM GPS device itself. Depending on which model of SCRAM GPS device is being used, there may be limitations to the shape and number of “onboard” zones the device can store for each offender. On-Server zones allow for polygonal zone shapes and an unlimited number of zones. |
| Violations | Violations refer to events where the client has entered or exited a zone when a schedule required them to be either in (inclusion zones) or out (exclusion zones) of the zone. In general, an exclusion zones will default to a 24/7 schedule. Neutral zones automatically generate alerts, but have no schedules and therefore no violations. |
SCRAMNET GPS Program Configurations
| Term | Definition |
| Users | The officers, agents, case managers, and administrators who use the SCRAMNET GPS monitoring system |
| Admin, Officer, Guest | Different access levels for a user |
| Primary Agent | The primary person monitoring the client |
| Recipient | A user or other persons who are set up to receive email or text messages of alerts generated by the client |
| Accounts | The billable caseload for the customer that has clients assigned to it. |
| Sub-account | An caseload below a “parent” account |
| Account Setting | Configuration values for the monitoring program/account. For example, time zone, date format, etc. |
Monitoring Settings
| Term | Definition |
| Supervision Plan, Rate Plan | Determines how frequently the bracelet gathers a GPS point (“Location”), and how frequently the point is transmitted to the server (“Transmission Frequency”). For example, a 1×1 rate plan means a GPS point is gathered every 1 minute, and transmitted to the server every 1 minute. |
Zones
| Term | Definition |
| Zones | Geographical areas defined on a map where the client can and cannot go. |
| Inclusion Zone | An address, on the map, that defines an area where the client is allowed to be. These are generally “home” and “work.” The zones are shown in green on the map. |
| Exclusion Zone | An address, on the map, where the client is not allowed to be. These are generally victim’s home and work. The zones are shown in red on the map. |
| Neutral Zone | A zone used to track when a client enters and exits. This type of zone does not generate a violation |
| Account Zone | A zone defined at the account level and can be applied to one or more clients in the account |
| Schedule | Determines when the client must be in an inclusion zone. For example, must be at home between 7:00 PM and 7:00 AM |
| 24/7 schedule | Client is required to be in an inclusion zone 24 hours a day. For example, while on house arrest. |
| Overnight schedule | A schedule that goes overnight. For example, client must be at work between 11:00 PM to 7:00 AM the next day |
| Grace period | The number of minutes a client is allowed to arrive late to an inclusion zone without generating a violation |
| Drive time | The amount of time a client is allowed to drive between two inclusion zones (for example from home to work) |
| OnServer Zone | The zone information is stored on the server. Violations are generated by comparing GPS points from the bracelet to zone and schedule settings |
| Onboard Zone | The zone information is stored on the bracelet |
| Zone type | On the map, zones can be rectangle, circle, polygon. For example, if a client is not allowed to leave the county, the customer would create a polygon inclusion zone around the entire county |
Violations
| Term | Definition |
| Inclusion Zone Violation, schedule violation | Client was not within the zone (such as work or home) during the schedule timeframe. |
| Exclusion Zone Violation | Client entered an exclusion zone |
| Strap tamper, tamper | The integrity of the strap is compromised |
| Device tamper, tamper | The backplate for the bracelet has been compromised, or removed |
Environmental Factors
| Term | Definition |
| Communication failure, no cellular communication, comm failure | The bracelet is unable to communication data over the cellular network |
| Location failure, no GPS location | The bracelet is unable to report its location information |
Battery Status
| Term | Definition |
| Device is plugged in, unplugged | The SCRAM GPS bracelet is attached to the charging cable and plugged into a power outlet, or it is not |
| Battery charge level | The amount of battery power left in the device expressed as a percentage |
| Fully Charged | The device battery is at full capacity |
| Battery Low | The device battery has roughly 20% of its life left and should be charged soon |
