Types of Door Access Security Systems
These types of readers tend to make use of a radio frequency. With this type of access system, the door reader sends a broadcast signal out to the key tag or card. This happens when it is passed in close proximity to the door reader. The energized tag or card credential responds by sending back a signal to the access control reader. The encoded signal contains the identification as programmed, which allows access. The door reader then sends a response whether to unlock the door or not, based on the card authorization.
Traditional Credentials
While technology is evolving, the most common types of credentials used for door access systems still remain keycards, numerical codes, and fobs. These tried and true methods are cost-effective and simple to implement.
Smart Technology Door Readers
Some of the more modern door readers are seen as smart devices that connect to the overall network. These devices hold a unique ID code for all of the persons who would have been assigned authorized access to the system. The reader may have a controller function built-in and matches the unique ID to its database. If acceptable the door is unlocked by the reader and controller. Therefore the reader controls the lock on the door, and may even be harnessed to indicate if the door is opened, all using various sensors.
An added benefit here is that this local storage still works should a network issue arise. Business can still continue as usual, just some form of backup power is needed as the smart technology door readers can be powered over ethernet (PoE).
Add The Smartphone
The wide use of smartphones can also make it easy. Some of the modern door access readers can read a unique code as provided by your smartphone. It is here that an app running on your smartphone can connect via bluetooth to the door access reader. The reader verifies the credentials of the app and determines then if access is granted. This all happens within a near field proximity.
Biometric Door Access
Some areas may be a bit more sensitive and may need more stringent measures for access. As such the door access system can be programmed with biometric readers, which adds precision and enhanced security details. These types of door access readers can be from fingerprint to facial recognition readers. The level of sophistication can include finger-vein, and even eye recognition details. Ideally a chat with your respective security provider can determine how extensive you can tailor your door access system.
