How a Door Access Control System Works


You may have heard of the term “access control,” but what exactly does it mean? Access control is a broad term that refers to the security of doors and alarm systems. These services allow companies to monitor and restrict entry into a specific area.

Door access control systems can keep inventory safe, secure intellectual property, and limit and restrict access to personnel. Property and employees are protected, and burglars are deterred, resulting in increased safety. With door access control systems, employers can track activity, reduce the risk of theft, and protect assets.

Door access control is used in a variety of industries, including banking, education, finance, government, healthcare, religious services, industrial, life sciences, military, retail, utilities, and commercial buildings. Nearly every business can benefit from the use of a door access control system to boost security and increase peace of mind.

How Does It Work?

Door access control systems operate off of an electronic locking device. This device can be placed on an interior or exterior door. In order to enter the building or room, the user must present the appropriate credential – most likely a key card. The key card is swiped on a card swipe reader or placed over a card reader. In some cases, a code may be required, which means that the user will be prompted to enter the correct code on a keypad.

Card readers are recommended for areas that require a high level of security. For example, rooms that have money, collectibles, or other highly sought-after assets will benefit from card readers. Readers are also good choices in areas where you’ll have to re-key the lock often. Cards are easy to program, so, if there is a lot of turnover at your company, card readers are ideal.

Door access control systems use what is called a controller. Controllers tend to operate around 32 control points, but larger ones can handle more. While each controller has its own software, a server runs the master software. Some servers may run hundreds of controllers. If there are several buildings, each one may have its own server.

Besides allowing and restricting access, door access control systems can be used with video and alarm systems so you can see who is entering a building and view any event that would cause the alarm to sound.

Features depend on the system you choose, but most can print badges, deactivate cards, and replace lost ones. You can also manage cardholders and specific areas, which is helpful if you lose or gain employees or if a current employee loses or gains access to a certain area.
