If you carry an access card, ID badge, or keyfob then you already use an access control system. But how does it really work? Laymen initially believe it’s just a card reader on the wall.
Once you get deeper into access control, you realize a few behind-the-scenes parts make unlocking possible.
Let’s explore how access control systems work, their benefits, how they fit into the security puzzle, and what’s the best use case for you.
An access control system allows you to manage, monitor, and maintain who can unlock certain doors and at what time they can access them. The simplest access control “system” is a standard deadbolt with a brass key. The basic modern access control hardware consists of an access controller, reader, and credentials.
Access control systems are not restricted to doors. You can manage access to different objects, including the most popular: Windows, elevators, gates, lockers, and printers. The standard form of workplace access control is moving from on-premise solutions to the cloud, while the preferred access method transitions from an access badge to a mobile credential.
The increasing security threats make access control a necessity. The interoperability of modern access systems makes it possible for every business, even ones located in multi-tenant buildings, to take control of their access management.
The purpose of access control is to provide quick, convenient access control for authorized persons while, at the same time, restrict access for unauthorized people. Besides the evident security reasons, there are additional benefits to implementing an access control system:
Access control systems vary widely in type and complexity. Still, most access control systems consist of similar basic components that can be divided into three groups: User-facing, admin-facing, and infrastructure components.
Essential for managing and securing access to restricted areas, user-facing access control components are the ones users perceive and interact with, making them vital for seamless user experience and convenience. Users usually come across the following components:
The admin-facing side of an access control system is the management dashboard. Authorized users, such as office administrators or IT managers, use it to set access permissions and schedules, determining who can access specific areas and under what conditions. Modern businesses often use cloud-based dashboards for remote management and advanced features. Advanced systems, like Kisi, allow automation of tasks like issuing credentials by integrating with employee directories through APIs or services like Google Apps, Microsoft Entra ID, or Okta.
Most users are less familiar with the infrastructure components, like access panels, locks, and cables, given they’re closely connected to the building infrastructure. While most infrastructure components are necessary for the access system to work, some can serve to help companies migrate to the cloud with ease:

While trying to create a welcoming experience for visitors, businesses need to consider valuable resources, private information, and sensitive data that can fall into the wrong hands. Modern visitor management systems enable you to impress visitors while ensuring compliance and security.
Unlike the old-fashioned method of logging visitors by hand, modern visitor management systems enable you to assign temporary visitor credentials and keep track of who is in your space and where they are at all times. Encoded in each credential, usually a badge, link, or QR code, is a unique identifying number for the credential holder. Each ID number has a designated level of access, allowing the visitor to access certain doors during a specific period.
A certain feeling of trust is inspired in visitors when they have access to the needed space even before they are greeted by the receptionist or they are able to self-check in if the process is automated. As a first impression, this action makes your organization appear modern, welcoming, and diligent. On your end, this action ensures that everyone who enters your space has entered identifying information into your system, meaning you have logs for compliance and potential incident mitigation.
The value of electronic visitor management is not only about giving that special guest treatment. Among other perks, it amplifies the worth of your current business, creating an extra real estate opportunity. Office buildings with a proper visitor management system often sell or rent for higher rates than comparable buildings without it.
Vital for modern organizations, streamlined visitor management enhances security and reduces operational overhead. Whether for office buildings, industrial facilities, or educational institutions, automated visitor systems offer the following benefits:
Enhance visitor experience, maintain a secure environment, and ensure compliance with detailed visitor schedules.

A critical component of any comprehensive physical security strategy, intrusion detection serves as the first line of defense against unauthorized access, breaches, and potential threats. If intrusion detection once meant sounding an alarm when an intrusion occurs, modern systems provide real-time alerts, video verification, and automation capabilities. As business security threats are growing and becoming more sophisticated, implementing an effective intrusion detection system is necessary to reduce the risk of theft, vandalism, and other security breaches.
An intrusion detection system (IDS) is a security solution designed to monitor and detect unauthorized access or unusual activity in a physical environment. An IDS is an early warning system that alerts security personnel to potential breaches or attempts to enter restricted areas so they can react to and proactively prevent potential incidents. These systems use a combination of sensors, detectors, and other technologies to track movements, identify intrusions, and trigger alarms when necessary.
There are several types of intrusion detection systems, each tailored to different environments and needs. For instance, perimeter intrusion detection systems (PIDS) are commonly used outdoors to monitor fences, gates, and other boundaries. These systems often use sensors such as infrared, microwave, or vibration detection to alert security teams of any attempts to breach the perimeter. Inside a facility, interior intrusion detection systems monitor doors, windows, and other entry points using motion sensors, glass break detectors, and pressure sensors. Modern, cloud-based solutions integrate with other security measures like access control, surveillance cameras, and alarm systems to provide comprehensive protection.
