Access control systems are crucial for business security. These solutions give employers the ability to control who has access to certain areas of a building.
It’s the ultimate way for business owners to track who enters a facility, when they do it, and what doors they use. A simple credentialing system can restrict access to floors, specific rooms, or whole departments within a building.
In short, access control systems prevent people from entering places they don’t belong. Instead of keeping a security guard at every door to check credentials, a simple access control system will allow authorized users to move throughout an area.
What’s the best access control system? This guide takes a closer look at the top access control solutions available on the market today.

When it Makes Sense to Invest Into Access Control Systems
Any business with a physical presence should consider an access control system. Even a simple access control solution can replace traditional keys in a building. At the most basic level, these systems can keep customers and visitors away from employee-only areas of a building.
Access control becomes a bit more advanced for certain business types.
Businesses that need to restrict access to sensitive information can implement an access control system based on credentials. For example, every employee might have full access to levels one and two of a building, but only staff with higher clearance levels can access the third floor.
Organizations that want to improve security are ideal candidates for access control systems. If you don’t want employees or visitors to roam freely throughout a building, an access control system is a cost-effective solution to this problem.
Many people associate access control systems with government buildings, police headquarters, military buildings, and facilities with highly sensitive information. But really, any business with a physical presence can benefit from these security solutions.
They can be used at hotels, schools, hospitals, corporate headquarters, and more.
Let’s say an office has a daily laundry service. The driver could be given an access card to enter a specific area of the building for pick-ups and drop-offs without being able to go into any offices. And the systems will record when the laundry service was there.
Businesses without a physical presence don’t have any need for an access control system. Or if you’re running a small coffee stand with just a few employees, you probably won’t need a security solution this advanced.

Methodology For Choosing The Best Access Control Systems
Certain factors must be evaluated when you’re shopping around for an access control system. This is the methodology we used to narrow down the top picks in this guide. Use these considerations to help narrow down your options and weigh their importance according to your personal needs.
Type of Access Control System
Access control systems come in all different shapes and sizes. Generally speaking, these solutions can be segmented into four main categories:
- Local — On-site access control systems are hosted on local servers. These are typically managed by an in-house IT team. Access control providers use a security integration vendor to manage software updates and maintenance.
- Cloud — Cloud-based access control systems are the most popular and easiest to use. Since everything is hosted in the cloud, the centralized management system can be accessed and controlled from anywhere. You won’t have to worry about on-site servers, additional hardware, or physical maintenance.
- IoT — An Internet of things control system connects with “smart” machines. These systems connect with a wireless network to securely open and restrict access to doors.
- Mobile — Instead of using a physical access card, authorized users can enter doors using smartphones, tablets, and wearable technology.
Each solution has advantages and drawbacks. The best option for your business will depend largely on your needs and infrastructure. But for the most part, cloud systems are the most user-friendly and easiest to scale. Outside of type, here are other things to consider when choosing access control systems.
Installation and Support
The vast majority of access control systems require professional installation. This can be handled by the provider directly or a third-party dealer.
Costs associated with installation vary from one system to another. Some providers can handle an unlimited number of doors. Others have capacities for each control panel. Make sure you understand these requirements ahead of time, as you might have to install additional control panels to accommodate the access control system.
In a perfect world, the system will run without any issues after the installation. But what happens if you have a problem or a card reader fails?
Find out what type of support the provider offers for future on-site visits beyond the initial installation. How soon will they resolve the problem? Will this cost you extra money? Or is it covered with your plan? How long do they provide support for?
Credentialing and Security
Security is obviously a top priority when evaluating access control systems. Avoid providers that are using outdated technology. Beyond basic access control, the best systems include alarms, video surveillance integration, and lockdown modes during repeated attempts to access a secure area.
Access control systems using proprietary technology are less vulnerable to breaches compared to open source solutions.
You should have different options for managing credentials. Some businesses can even provide multi-credential authentication for certain access levels.
Depending on the areas you’re restricting, you may want to choose an access control system with advanced security features. For example, some systems have alarms if a door is propped open for too long.
You should be able to implement rules for specific scenarios associated with emergencies. The best systems allow you to program doors to automatically lock or unlock in the event of a fire or a break-in.
For facilities that commonly have guests or visitors, make sure the system allows for temporary guest credentialing.
Administrative and Reporting Tools
Access control reports allow managers and administrators to observe how employees and other users move throughout a building. You’ll be able to see who enters a particular door at an exact time.
These reports are extremely useful if you ever need to investigate suspicious activity. You can go back and see exactly who was in a specific area during the time of an incident.
The best access control systems have tons of real-time information and detailed reports for admins. Ensure that reports are stored indefinitely, so you can refer to them months or potentially years down the road if needed.
