When it Makes Sense to Invest Into an Access Control System

Any business with a physical location can benefit from implementing access control. Simple solutions modernize keys and eliminate them altogether. And even at this essential level, they keep employees, customers, and visitors where they’re supposed to be.

However, access control systems come in all shapes and sizes from simple key replacements to robust solutions for businesses with hundreds of locations across the country and everything in between.

Whether you’re handling sensitive information, want to restrict people from roaming around your building unattended, want to eliminate unnecessary distractions throughout the day, are tired of using a traditional key, or need security measures in place for safety reasons, there’s a control access solution to match your needs.

While it’s great for military buildings, police headquarters, medical facilities, and government institutions, access control use cases go beyond those with strict security requirements.

Even if you’re just tired of locking yourself out or forgetting your work keys at home, an access control system is an affordable way to modernize business security.

They’re even useful for other scenarios, like hotels, schools, offices, corporate headquarters, and more. 

#1 – Kisi — The Best Access Control System for Most


Best for Most

Industry-leading access control system for touchless access via smartphones. Simply tap your phone for instant access to your building, elevator floors, and any other controlled areas. Includes remote lock management, video snapshots, scheduled locks and unlocks, and visitor management features.

Kisi is a cloud-based access control system that launched in 2012. Since then, it has quickly become an incredibly popular and modern way for businesses to maintain physical security company-wide.

Like most access control systems, Kisi offers solutions that include key fobs and physical cards. But it’s best known for its smartphone touchless access control system. It’s modern, easy, and designed to work with just about every type of door.

Since most people have their phones on them all the time, the touchless phone system is incredibly convenient. Employees won’t have to worry about carrying around an extra fob or plastic card everywhere they go nor do they have to worry about losing something so small. 

There are two setups, including a standalone option with a Kisi reader at each entry point that only requires your team to tap their phone and go. All of Kisi’s readers are tamper-proof and connected via IP for secure IT-grade equipment without needing an IT team to manage them.

The other option lets users unlock doors through the mobile app and doesn’t require a Kisi reader. It’s more cost-effective than the standalone option and is perfect for smaller businesses.

Kisi even has advanced access control solutions for contactless elevator access and thermal scanning integrations so you can rest assured knowing your business is secure at all times.

With Kisi’s access control systems, you also get:

One of Envoy’s newest features is a visitor questionnaire designed to help stop the spread of COVID-19. You can even set up automated surveys that deny access to users based on their answers. For example, if someone has been sick in the past 14 days, you can deny them access automatically.

Envoy’s visitor management system is a modern alternative to hand-written badges and manually tracking down employees when a guest arrives. Your staff will receive an instant notification whenever a visitor comes to see them. You can even give each visitor custom clearance levels depending on the purpose of their visit.

On top of that, you can screen visitors based on their appearance in internal or external watch lists.

You can even send upcoming visitors directions to your office, a formal invitation, and a post-visit survey to gather continuous data on how to improve the visiting experience.

Some of the key visitor access management features include:

Custom sign-in flowsPre-registration formsVisitor screeningDigital document scanning (NDAs, waivers, etc.)Badge printingVisitor photo capture

There are also dozens of integrations, including directory services, legal document platforms, HR and recruiting, parking management, rooms, and wi-fi providers.

Despite its lack of advanced security features, you can seamlessly integrate your new visitor management platform into your existing workflows with minimal changes to your processes.

On higher tiers, you can even put your brand front and center with a white-labeled visitor management experience.

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?

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.
