Access Control

In the fields of physical security and information security, “access control” is the selective restriction of access to a place or other resource. The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization. Locks and login credentials are two analogous mechanisms of access control.

Swipe Cards

Magnetic (mag) stripe card access control — also known as swipe card access control — is a low security controlled access solution. While swipe card systems are better known as door entry systems, they can also be used for other levels of security and offer a wide range of additional features.

Door Sensors

Door sensors are an essential component of your home security system: they let you know when someone is entering your home. These devices are made up of two parts, which form a circuit when they’re kept parallel to each other. When someone opens the door, the two parts separate and break the circuit, which triggers the control panel to sound an alarm.

Alarms

A security alarm is a system designed to detect intrusion – unauthorized entry – into a building or other area. Security alarms are used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders.

Line Supervision

Line supervision is the means for monitoring the communication link between a sensor and the alarm control center. A means where a known current is present on the line to the central station. Cutting or shorting the line changes this current, which results in an alarm.
