THE ULTIMATE GUIDE TO ACCESS CONTROL
What is access control?
Access control systems are an important and integral element of security systems to protect property, people, and resources.
The role of access control security:
- To regulate who can enter a building or a space.
- To minimize risk to a business or organization.
- Electronic access control has replaced traditional lock and key systems as more secure.
- The problems of lost or stolen keys, retooling locks, and the inability to view access activity.
Why access control security is important
Replacing traditional locks and keys with electronic security and access control strengthens security. Electronic access control systems can be programmed with different levels of access for individual users and groups, which enables security teams to impose the strongest levels of security where they are needed most.
How access control security works
A user who is authorized to enter a building or secure area presents credentials to an access control reader positioned at the entrance or door. The reader transmits the credentials’ data to software which validates the credentials against a database of authorized users.
ACCESS CONTROL COMPONENTS
Door access control systems have a number of basic components, each with its own importance for a fully functioning system. It’s important to understand how access control components influence the convenience and security of the system in order to deploy a solution that fits your needs.
- Door access control credentials: Credentials are what users will present to a door reader when they want to enter the building.
- Door readers: Door readers can be installed inside and outside of the building to provide security for areas with different levels of vulnerability.
- Controllers and access control boards: These are the “brains” of the access control system, acting as a link between the door reader and the user database. These units are usually installed behind restricted doors, as they contain vital data and information that should be protected.
- Access control software and data storage: The software for access control systems is a vital tool for managing the database of authorized users. The database holds the details of the network of access controlled doors and authorized users together with their access levels.
- Electronic locks for door access control: Electronic door entry systems remain closed until a user’s credentials are validated and a ‘release’ signal unlocks them.
- Commercial security doors: Electronic locks for access control are generally used in conjunction with commercial security doors, which have the strength and durability to resist threats. These doors can cope with high traffic volumes and continuous use by larger numbers of users with minimal maintenance. They also have the performance to withstand different internal and external environmental conditions, such as extreme weather conditions.
- Data networks and cabling: Dedicated cabling has traditionally been used to connect security access components. A fast, secure and reliable data network is essential for efficient access control operations. The networks must be able to transmit signals securely between controllers, readers and electronic locks.
- Power supply: An access control system requires power for door readers, controllers and electronic door locks. Power can be connected using conventional cabling to each component or supplied via a data network using PoE technology. This simplifies installation and reduces costs because no separate cabling is required.
