 Access control systems provide end-to-end 
control on who can be allowed and who 
cannot be allowed to enter the office or 
premises. Access control systems authorize, 
recognize and authenticate entry of 
people/staff into the premises.
Beneficially, the access control system not only tracks and records data of visitors and employees, but also helps in integrating 
the payroll software, to produce automated and system generated attendance system.
Each access control system biometric helps in saving time and resources that happens with the manual attendance system, and 
increases the productivity and profitability of the organization.
The proximity access control system deployed in offices and factories allow for time zone settings, and ensure an absolute 
safety environment.

Getting started with access control can be overwhelming at first with so many technical terms 
and things to wrap your head around. But understanding access control systems is really an 
achievable goal - especially after reading this guide. This is really a 101 crash course guide for 
access control systems. If you want to get a relatively quick idea of how access control works, 
you’ve come to the right place. 
Why do we need access control? 
The purpose of access control is to provide quick, convenient access control for authorized 
persons, while at the same time, restricting access for unauthorized people. Here are more 
reasons why access control is playing a significant role in your organization:
Access Control Infrastructure
 Access Control infrastructure is to most people the most mysterious aspect of access control systems. 
Obviously there are electronic locks installed - but what most people don’t know: Those locks are all 
centrally wired to your IT room. This means: A power or signal cable runs from the lock through the walls into 
your IT room where the access control panel sits. The access control panel gives the lock the signal to unlock 
when it receives the request to do so by the card reader. There are different topologies (as people call it) but 
for the basic understanding of access control systems let’s just assume this described flow for now.
