The term “Access control system” refers to a type of setup that allows or disallows access to a person to a certain facility or area. These are used most commonly to control access, and only allow entry to some individuals – those who are permitted or authorized to enter. Access Control Systems are of various types, which range from the most basic to those that are technologically advanced. The simplest ones have a door lock that lets in only people having a key for entry. The high-tech ones give notifications about events in real-time and can offer support to various reading technology combinations like the biometric & card, pin & card, etc. These are usually of 2 types:
Standalone Door Access Control Systems
These happen to be the simplest types of access control units that can be found today in the market. This kind of access control can be used in just one area and is not associated with networks in similar locations.
For example, a bank ATM situated far from its branch or a home with its entrance having just one access control keypad only lets in cardholders. Typically, standalone keypad access control systems do not feature over 10 access control points. Such points are programmed to separate function and are not joined to a “host” or a central network.
Networked Door Access Control Systems (TCP/IP)
This kind of system means an access control method that includes a single or multiple access points that are joined to a central server or host or are controlled individually. These transfer real-time data about door access. The entire system is in a type of network that makes it simple and convenient for operators to manage from just one area.
Standalone VS Networked Door Access Control Systems
As compared to networked access systems, Standalone access systems usually cost lesser. You can configure network systems and customize them according to your own needs, and monitor them with the help of a PC. Standalone Door Access Control Systems are only used in areas or facilities where there is a need for lower grade security, such as in smaller organizations. On the other hand, networked access systems are only used by bigger organizations that need a higher level of security.
It could be that a facility might use a standalone access system to secure as many as 10 doors. However, the same type of control will be there for the access points. On the other hand, Networked systems may have different security levels for different access doors. You may integrate these with the help of video surveillance systems to get a security package that is more comprehensive.
Types of Standalone Door Access Control Systems
These draw power from the battery, and offer “all-in-one” control of access for a single door. These locks have replaceable internal batteries that can be unlocked with the aid of a proximity card keypad or both used in a combination.
These are advantageous in the sense that you can install them within a few minutes, and operate them quickly. However, these stand-alone locks are not a part of a network that is monitored broadly. But some of these offer readers that are hand-held and can draw the audit trail from the stand-alone lock.
In the field of commercial access control, these happen to be the most famous option. You can use them with ease. Even when the cards get lost, you can simply deactivate those and have new cards issued. For more security, you may also combine these with photo IDs. Proximity cards are the commonest and may work from 1 – 36 inches from any sensor.
Due to a lack of contact between the reader and the card, stand-alone proximity access control system is extremely reliable and there are only minimal risks of wear and tear. These are also lower in cost.
These offer electronic auditing with the aid of a network while keeping on using a physical key for lock activation.
The systems are less costly and are common options for secure access to single doors. These can easily be used but happen to be of reduced security, given that users tend to write the entry code down or “lend” the same to others. Also, these do not offer detailed audit trails until the time you offer unique codes to every person who is authorized an entry.
These allow access to users based on their physical features, such as retinal scans, handprints or fingerprints. By far, these happen to be the safest access control methods. But these are also quite costly and may also appear invasive to staffs or workers who are forced to continuously keep on wearing them. The earlier models were not so reliable in outdoor situations, which made them unsuitable for exterior security access.
These single door access control systems give door access upon an audio door answer.
