2.0 Introduction

2.1 Access Control Overview

An access control system protects and preserves an enterprise's resources by
providing authentication, authorization, and administration services. Authentication is
a process that verifies a user's identity. If the user is verified, the system then either
grants or denies access to specific areas and resources. Administration includes the
creation and modification of user accounts and access privileges.
An access control system consists of hardware and software, usually configured in a
network environment over a standard network protocol. Access control units, readers,
door strikes, and video and other devices, for example, are configured to control and
monitor the access to a company site.
2.2 NetAXS™ Access Overview
A NetAXS™ access control system consists of a host system and NetAXS™ access
control units that meet existing N-1000-III/IV specifications and that communicate
with each other and with a variety of input and output devices over the RS-232 and
RS-485 network protocols. See
illustrations of the supported NetAXS™ system configurations. A NetAXS™ access
control system is configured and maintained via either the host system or a web server
using RS-232, RS-485, or Ethernet network protocols.
This document describes how to install and configure the NX4L1 access control unit.
