Access control systems are not only required for financial and government facilities now a days but for all kinds of businesses, small or large. However not every business requires the same kind of access control. Each business has a different requirement and it is important to weigh in all factors before you finalize on a particular system. In order to decide the right kind of access control for your business, you should know all types available in the market.

1. Standalone vs. Network based

Standalone access control systems are basically isolated systems designed for individual doors. Each system controls that specific door and in order to change or control the system access, it needs to be done at the door level. These type of systems are well suited for smaller facilities with minimal or no access-restricted doors. They are simpler to set up as compared to network based systems.

Network based systems on the other hand offer centralized control of multiple doors with the help of wireless networks. They are complex to set up, however once installed, they can control all doors from a central location. Apart from that, you can also use the system log to check who accessed the system at what time. This type of system is more helpful for medium to large businesses with a lot of entry-restricted doors and many users.

2. Hardwired vs. Wireless

Hardwired systems offer a better security solution in terms of stronger system infrastructure. However, these systems are difficult to install in an existing building, hence are usually installed at the time the building is constructed.

Wireless systems are battery-powered and use internet to communicate within the system. They require gateways or access points to establish communication between individual door and the central system. These gateways have a limited range, hence need more complicated networks. Setting up a wireless system in an existing building is not a concern since it does not require any physical modifications in the building.

3. Cards vs. codes vs. biometrics

A key card is the simplest type of access method. Cards or physical tokens are issued to users which can be inserted into a card reader or read using a proximity sensor for secure access through doors. Although simple, they can create an issue in case the card is stolen or lost. In that case, the access for that card needs to be retracted in order to maintain the security.

The second type of access method is key codes or pins wherein the user needs to enter a certain code in order to gain access to a particular area of the building. This however is a problem if an employee forgets the code or writes is down somewhere and loses it, or worse discloses it to an outsider.

Biometrics is the third form of access method which is considered to be the most effective one in terms of security. These systems use unique identifiers in hum body like fingerprint, handprint, retina, face etc. These are the most secure but most expensive and complex to install.

For enhanced security requirements, there is a two-factor authorization method wherein a user has to provide two or more identification such as a key card along with a code or an ID with a hand print. They are the most complex but most secure methods of access control.
