Smart Building Tech: Linking Mobile Credentials, Keycards, and AI Video Intelligence

Modern office buildings are increasingly not just buildings but ecosystems of technologies which continuously communicate with one another, including such components as door locks, cameras, people identities, their mobile devices, elevators, and other components. A simple plastic card that unlocks the door is not how physical security works any more.

These trends are supported by industry statistics as well. HID’s 2026 report found 73% of respondents identified identity management as a top strategic priority, while security concerns have become the most important reason to use mobile credentials instead of convenience.

The traditional keycards have not gone away either as 84% of companies that use mobile credentials keep using physical cards as well. The logical move would be the integration of those credentials with AI-enabled video analytics.

Why Smart Buildings Need Smarter Access Control

Traditional office access control generally follows a simple process. The employee shows a card, and the system determines whether the card is allowed to enter. Depending on the decision, the door gets unlocked or locked.

That approach controls the door, but it provides limited information about the actual event.

If an employee’s card opens a restricted entrance at 11:30 p.m., for example, an access log may identify the credential and timestamp. It may not immediately tell security personnel whether the authorized employee entered, whether another person used the card, or whether someone followed through the door without presenting a credential.

Smart-building technology adds additional context.

An access platform can centralize users, entrances, schedules, permissions, and events when accessed in the cloud. When these platforms communicate with surveillance systems, a security team can move from simply asking “Which card opened the door?” to asking “What actually happened when that door opened?”

That distinction becomes important for large offices, corporate campuses, laboratories, warehouses, and multi-tenant buildings.

Mobile Credentials Are Changing the Employee Experience

Smartphones are gradually becoming digital keys.

A mobile credential is an authorized digital identification stored within the employee’s smartphone or other supported device. Depending on the system, an employee can present the phone to a reader or use an application to gain access to an approved entrance.

The operational advantages can be significant. If a new employee starts work, administrators can issue digital access without necessarily printing and distributing another physical card. Temporary access may be useful for contractors or vendors as well.

Mobile access does not mean keycards have become obsolete.

Hybrid approaches tend to be more sensible, since organizations must allow for various users, devices, buildings, and processes. An employee might use a phone, while a contractor receives a temporary card, and another worker continues using an existing badge.

The important development is therefore not replacing one credential with another. It is building an identity infrastructure capable of managing multiple credential types consistently.

Linking Access Events With AI Video Intelligence

The access control system becomes a lot more valuable if it works together with the video stream.

Modern building automation is moving past simple lock-and-key mechanisms. Deploying unified facility access control with cloud-based video intelligence allows security teams to verify employee badge swipes against camera footage instead of treating access logs and video as separate sources of evidence. For instance, Coram’s access control platform can associate door events with video while providing centralized management for credentials, access rules, schedules, alerts, and multiple locations.

This type of integration can shorten investigations.

Consider a security team receiving an alert that a restricted server room door was opened outside normal operating hours. In a disconnected environment, an employee might first inspect the access control log, identify the credential, open a separate video platform, locate the relevant camera, and manually find footage from the correct time.

An integrated environment can place the access event and visual context much closer together.

That helps staff determine whether the event was routine, accidental, or suspicious without spending unnecessary time switching between systems.

AI Search Makes Large Camera Networks Easier to Investigate

Smart buildings can contain dozens or hundreds of cameras. More data collection is only effective when proper retrieval of that data is possible.

Traditional security investigations often involve manually selecting cameras and reviewing timelines. AI-powered video search transforms this process by helping operators locate events based on objects, people, vehicles, behavior, or natural-language descriptions.

Suppose facility staff need to investigate how an unauthorized person reached a particular floor. Instead of reviewing several hours from numerous cameras independently, intelligent search tools can help narrow the footage that requires human analysis.

The goal is not to remove people from security decisions. AI can reduce repetitive searching so trained personnel can spend more time interpreting events and deciding what action is appropriate.

This becomes increasingly important as organizations connect more buildings to centralized security operations.

From Door Security to Building Intelligence

Integrated access data can also support areas beyond incident response.

Badge activity can also give information on how buildings are actually being used. Facility managers may identify entrances experiencing unusually high traffic, determine whether certain office areas remain largely unused, or understand occupancy patterns across multiple locations.

Historical access information can also be helpful for organizations to review policies. If employees consistently request access to spaces outside their assigned areas, administrators can determine whether permissions or workflows need adjustment.

The same connected infrastructure can support visitor management, elevator access, parking gates, emergency procedures, and temporary contractor permissions.

However, increased connectivity also implies more responsibility. Organizations need clear policies covering who can access security information, how long data is retained, when video can be reviewed, and how employee privacy is protected.

Smart does not automatically mean secure. Every connected system needs appropriate cybersecurity, authentication, permissions, auditing, and software maintenance.

Building a Hybrid Credential Strategy

Not all readers, cards, cameras, and locks need to be upgraded simultaneously by organizations making plans for upgrading.

A phased approach can often make more sense.

Existing keycards can coexist with mobile credential systems for workers to favor them.  Compatible readers can be retained where possible, while aging infrastructure is gradually replaced. Video systems can also be integrated with access events as facilities modernize.

The priority should be interoperability.

An intelligent building has systems capable of exchanging useful information. Access control knows who was authorized. Cameras provide visual context. AI helps locate relevant events. Cloud management gives authorized teams visibility across locations.

Together, those technologies provide something that standalone door systems cannot: a clearer understanding of activity throughout the facility.

Conclusion

The smart building is evolving into an interconnected environment where physical identity, mobile technology, access control, and video intelligence work together.

Mobile credentials can make entry more flexible, while keycards continue to serve users and situations where physical credentials remain practical. Connecting both with intelligent video provides security teams with greater context when unusual events occur.

Well, it is not about choosing between a smartphone, a card, or a camera. It is about connecting them so building operators can manage access efficiently, investigate incidents faster, and create safer workplaces without adding unnecessary complexity.
