In its simplest form, access control involves allowing certain people access to an area or resource while prohibiting others from enjoying a similar level of access. Systems that are used to restrict entry can prevent individuals from looking at sensitive data, taking advantage of various resources, gaining entry into areas for which they lack authorization and even leaving such areas. In this article, you'll discover the most important factors to consider when investing in an access control system.

#1 - What Is Your Objective?

The first step is to determine your goals. Access control solutions come with different levels of control. Your business or organization may only need minimal controls. On the other hand, you may want to deploy a system that offers a scalable solution that grows as your needs grow. Think about what you're trying to protect. How many entrances will you need to block entry? What level of security will you need to use? Will you allow those who have entered restricted areas to easily exit? Or, will the exits be controlled (requiring authentication before exiting is granted)? It's critical that you decide upon your goals upfront.

#2 - Type Of System

Next, you'll want to consider the type of security elements to use for identity verification. Some access control solutions use card readers. In this case, authorized personnel are given cards equipped with readable magnetic strips or a bar code. When swiped or placed in front of the card reader, access can be granted or denied. If the cards are misplaced or stolen, they can be disabled and replaced.

Other solutions use keypads and require the input of a code to gain entry. This type of access control system is less expensive than other systems. That being said, the codes can be easily compromised (intentionally or accidentally). Many newer systems use biometric data to validate identity. Fingerprints, voice, facial features and a person's iris can be used for recognition. A biometric solution is among the most expensive.

#3 - What Features Do You Need?

Most access control solutions can be customized with features according to your needs. Some provide timing flexibility to grant or deny access depending upon the time of day. Most systems provide robust tracking capabilities to output detailed reports. If you need the ability to quickly modify permissions throughout your system, many access control solutions have templates from which to work. Also, consider the value of having a standby battery that can maintain control in the event the power fails.
