An add-on is a software package that adds tasks, tools, or specific configuration settings to Security Center systems.
Entities are the basic building blocks of Security Center. Everything that requires configuration is represented by an entity. An entity can represent a physical device, such as a camera or a door, or an abstract concept, such as an alarm, a schedule, a user, a role, a plugin, or an add-on.
The BACnet plugin integrates your network of building automation and control (BAC) devices and sensors into Security Center.
An event indicates the occurrence of an activity or incident, such as access denied to a cardholder or motion detected on a camera. Events are automatically logged in Security Center. Every event has an entity as its main focus, called the event source.
An expansion server is any server machine in a Security Center system that does not host the Directory role. The purpose of the expansion server is to add to the processing power of the system.
Failover is a backup operational mode in which a role (system function) is automatically transferred from its primary server to a secondary server that is on standby. This transfer between servers occurs only if the primary server becomes unavailable, either through failure or through scheduled downtime.
Industrial Protocol Interface
The Industrial Protocol Interface plugin is a software module that operators can use to expose Security Center data to compatible client applications using protocols such as BACnet or SNMP.
A plugin (in lowercase) is a software component that adds a specific feature to an existing program. Depending on the context, plugin can refer either to the software component itself or to the software package used to install the software component.
A plugin role adds optional features to Security Center. A plugin role is created by using the Plugin role template. By default, it is represented by an orange puzzle piece in the Roles view of the System task. Before you can create a plugin role, the software package specific to that role must be installed on your system.
The Plugins task is an administration task that allows you to configure plugin-specific roles and related entities.
A role is a software component that performs a specific job within Security Center. To execute a role, you must assign one or more servers to host it.
SNMP traps are event messages sent by the SNMP device to the SNMP Manager.
