Being able to monitor and control who can enter and access your facility is a foundational element of physical security. But as security threats have continued to become more sophisticated, it’s important to understand that entrance control and access control
Access control is a broad term used to describe the systems that identify users and authenticate their credentials; thereby deciding whether or not the bearer of those credentials is permitted admission to either a physical or logical asset. Both physical and logical access control is cantered around regulating who or what can access restricted areas, but logical access control refers to restricting virtual access to data, digital resources and computer networks, whereas physical access control restricts actual pedestrian traffic to buildings, rooms and other tangible assets.
If access control verifies authorized personnel using their credentials – their face, fingerprints, PIN number, proximity card, etc. and decides whether or not they are permitted access, entrance control is the system which enforces that decision, by either opening to allow users to cross a threshold, or remaining closed to bar entry and potentially raising an alarm. Some entrance control systems, don’t feature a physical barrier, however, so what happens in this instance?
