How to Choose a Door Access System for Your Office? |
Posted: March 24, 2018 |
Access control systems let authorized employees get in and out of various parts of your office while keeping other people out. They can range from simple electronic keypads that secure a single door to large networked systems for multiple buildings that can include parking barriers, integration with time and attendance systems, and multiple levels of security. If you are just looking for very basic measures (i.e. cheaper) to secure a room, you can go for the numeric keypad system. Pin code typically can be from 4 to 8 digits long. The users just need to remember the pin code to access the room, and there is nothing to carry with him/her in order to open the door. Disadvantage include low security as pin code can be easily shared, and the pin code can be guessed by the would-be intruders by looking at which digits of the keypad are more worn out. Hence pin code reader is never recommended for mid or high security premises. The next type of door access reader will be the card and/or pin door access system. Each user is issued a token (e.g. door access card, key fob) and the user will tap the token on the reader to release the door lock. In addition to token, some systems allow you to configure it such that the user is required to key in a pin code in addition to tapping the token on the reader. Hence the advantage of the token-based door access system is that it is more secure than the numeric keypad system since each token is accounted for. Furthermore, if a card is lost, the system administrator can delete that card from the system easily. Such token based door access system can typically also cater to large number of users (in the thousands). For the more advanced card reader system, all the readers are networked to a computer running the door access control software. The computer does not need to be on for the card readers to work. However, whenever the HR or admin department wants to download the door access logs from the readers for attendance check-in check-out timings, they will run the software to pull down the logs from all the readers through the network to the computer. The disadvantage of the card reader system is that if the card is lost, any one with the lost card can access the room before the card is being reported as lost and deleted from the reader. Hence such token based card access system will not be recommended for very high security premises. Even if it is used in high security areas, it should be complemented by additional security systems such as CCTV cameras surveillance system. For offices with high security requirement, you will probably want to consider the fingerprint biometric based access control system. As fingerprints are unique to each individual, such biometric access control systems solve all the security problems of proximity card or electronic keypad based systems. The fingerprint biometric technology has matured significantly as compared to the early 2000s. Recognition response time and accuracy of fingerprint biometric system is now widely acceptable to be used for access control and time attendance purpose. The only disadvantage of fingerprint biometric is that there is still a small percentage of people (typically 2 to 3%) whose fingers are either too dry, too wet, groves on finger too shallow or fine, etc, whose fingerprints will have problem being enrolled into the system. For working environment where employees' fingers may be oily or get dirtied easily, fingerprint biometric system may not be suitable too. If all fingerprints on both hands failed to be enrolled, these small group of people can be given either proximity card or pin code for accessing the door. Finally, to have a peace of mind, make sure you get reliable commercial-grade access control system with easy to use software.
