What Makes Access Control Systems Such Reliable Security Technology?

By Chan Sprouse


By installing an access control system, it would be possible to secure the entry and exit points of any building or facility. It makes sense for businesses and commercial establishments to have a solid access control technology because it will ensure that only authorized personnel are allowed access to specific areas. In this manner, both security and privacy are improved significantly.

As compared to traditional lock and key system, computerized access control technology is more advanced in terms of keeping restricted areas secure. Since there are no physical keys to be used, locks can't be compromised because of key duplication. And since entry is usually granted by providing a password, passphrase, or PIN, it completely eliminates the problem of having lost keys.

A more advanced access control system makes use of biometrics, in which a specific part of a person is used as verification whether access will be granted or not. A biometric scanner can check the fingerprints or the retina of a person to verify authorization. Once identity has been verified, the access terminal will then release the electronic locks in the door or gate.

An access control system also helps to minimize the use of additional manpower for guarding entrance and exit points in buildings or facilities. It can also be used to track the work hours and activities of employees more accurately. The likelihood of fraud can significantly be minimized this way since there is less manual work involved.

It is important to get a general idea about the components that make up an access control system - the physical barrier, the access controller/reader, and the credentials. Entry and exit points such as doors and gates are secured with the physical barrier and the most common are electronic locks. Gates found on bus terminals and train stations often make use of turnstiles to secure entrance/exit points.

There are two options for an access controller and for smaller establishments, a stand-alone system is often used because it is less complicated to setup and all data is stored in the unit itself. On bigger offices, network or online-based systems are preferred since it offers more flexibility by using a user database. Credentials such as passwords, keycards, and fingerprints are used with the access controller.

When using an access control system, it is important to understand that there could be some possible loopholes that should be given attention. One popular security breach is by tailgating, which is accomplished when an unauthorized person follows one who enters a secure area. Risks like this can be easily avoided by laying out standard protocols and keeping the system constantly updated.

A good way of leveling up the security of your establishment or facility is by combining your access control system with an advanced surveillance system. This way you'll also be able to keep a close watch over all your operations and not have to worry about whether or not your personnel are doing their job properly or not. It's a critical area of internal control you should not overlook.
