How Door Access Control Systems Enhance Security

Door access control systems are electronic security measures that restrict entry to certain areas of a building or property. They authenticate user identities based on credentials, permissions and more.

Credentials can be physical, like key cards or fobs, or digital. The system verifies the information by communicating with a server on-site or in the cloud.


Door access control systems offer a variety of security tools that combat theft and vandalism. They can allow only authorized users to enter specific areas and prevent unauthorized people from entering them, and can also integrate with other business security features like video surveillance.

Modern systems feature access credentials in the form of a physical card or key fob, a PIN code, or biometric data such as fingerprints and face recognition. They work with a central controller, which can be installed on-site or remotely hosted in the cloud. At the entry point, the reader scans the credentials and communicates with the controller, who verifies the information to determine whether to allow or deny access.

If the information is valid, the controller sends a signal to open the lock and a message to the user to proceed inside. The system also logs the event for later reference. It can be set to alert building security if a certain amount of unauthorized attempts are made in a short span of time. The alarm can also trigger other security systems such as video surveillance, to begin recording.


Door access control systems eliminate the need for security personnel to verify a person at every entry and exit point. They automatically record a timestamped log of who enters and leaves the premises. This makes it easier to monitor patterns and spot unauthorized activity.

How a business uses the system also impacts its functionality. If it wants to improve incident response times, look for a platform that provides real-time security alerts and allows admins to visually verify entry and exit activities.

When choosing a door access control solution, property owners should consider ongoing maintenance costs and plans to expand security systems as the business grows. They should also make sure the hardware will be compatible with previous systems and be able to integrate alongside other systems, like video security, visitor management, alarms and more. A comprehensive report log is another feature to seek. It can help identify entry and exit trends to address unique pain points. DOTCOM’s system captures detailed access logs, providing clear visibility into activity and allowing for quick reaction to incidents.


Modern door access control systems help you eliminate the need for security personnel to manually open and lock doors, reducing operational costs. They also provide detailed logs that can be used for security audits, compliance reporting, and incident investigation.

The heart of an access control system is a door reader that authenticates credentials by comparing the user’s information to permissions logged in a database. The credentials can be something you have — such as an access card or badge — or something you know, like a PIN or password. Other options include proximity cards and mobile credentials that turn a user’s smartphone into a credential.

When the card or key is presented to a reader, it communicates with the reader through a magnetic field near-field communication (NFC) or agency identification (RFID). The reader then verifies that the credentials are valid by communicating with an access control panel on-site or a cloud-based server. If all conditions are met, the reader signals the door release to activate and unlock the door.


The best door access control systems make it easy for residents and employees to enter a building or room without the hassle of carrying keys. Users simply present their credentials to a reader—like a smart card, key fob, mobile app bar code, or fingerprint scan—to unlock the door.

The reader authenticates the credentials by communicating with a central panel on-site or a cloud-based server. The system checks the credentials against its database of permissions, and if they match, the door opens. If the credentials don’t match, the system denies access. It also logs the access event, including information like the user’s identity, time of entry and exit, and whether the door opened or closed.

Most modern systems have the added benefit of being able to integrate with other security and tech systems, enabling remote monitoring from any device. Some also come with timers that delay the opening of doors for security reasons. This feature is useful if you have valuable items at home that need protection. A few systems even allow you to change your preferences from a smartphone or other device.


Modern door access control systems allow for a wide range of credential options, including swipe cards, PIN codes, key fobs, and biometric scanning. This versatility allows owners to find the right level of security for their business, reducing the risk of unauthorized entry.

Once a person presents their credentials to the door reader, it verifies their authenticity with either an on-site security server or the cloud. If the credentials are valid and their permissions match what is on file, it sends a signal to unlock the door lock. If the credentials are invalid or don’t match what is on file, it will deny access.

Detailed access logs are available on most systems, allowing teams to review who entered and exited the building as well as any activity that may have raised red flags. This can help teams better understand what threats they face to create more effective defenses. This information can also be used to streamline operational workflows and optimize security protocols. Taking these elements into account can lead to improved productivity for employees as well as a more efficient property management process overall.
