From alarm notifications to video surveillance: why security data must be centralized

From alarm notifications to video surveillance: why security data must be centralized

Part of the topic series Security Monitor
An alarm is triggered. At the same time, someone opens a door for which no valid authorisation exists. Seconds later, a camera provides an image, but the information is spread across three separate systems. This is where the real challenge of modern security architectures arises: not a lack of data, but a lack of connectivity.

When every system operates in isolation: a daily security risk

  • Alarm systems report events without a direct connection to access permissions
  • Cameras provide visual data but no information about the current authorisation status
  • Access Control operates based on rules but lacks live context for security incidents
  • Security-relevant events must be manually consolidated and interpreted

The critical difference: events only become security-relevant through context

  • An access event only becomes critical when it is linked to alarm or video data
  • Security teams need a unified situational overview rather than isolated alerts
  • Compliance requirements demand traceable event chains rather than individual data points
  • IT and security management require a shared real-time data foundation

How ZEUS® Security Monitor and ZEUS® Access Control work together

The real strength lies in the interaction between ZEUS® Access Control and the ZEUS® Security Monitor. While the Access Control system manages movement throughout the facility and controls authorised access, the Security Monitor acts as the central analysis and correlation platform.

Access is no longer simply a matter of “granted” or “denied”; it becomes part of a broader operational picture. If an alarm is triggered, the Security Monitor immediately shows which employees, visitors, or contractors are present in the affected area. Video feeds are automatically placed into context. This creates a comprehensive security overview instead of isolated system notifications.

From event to decision in seconds

In critical situations, the volume of data is less important than having the right information available at the right moment. The ZEUS® Security Monitor closes this gap by combining access events, alarm notifications, and video information into a consistent operational overview. Security personnel no longer have to work across three separate systems; they see one unified situation.

This also transforms operational response processes. Instead of analysing after the fact what may have happened, teams can take immediate action. Areas can be secured, movements traced, and risks assessed more quickly without media breaks or system changes.

Security becomes an integrated management function

As requirements driven by KRITIS, NIS2, and internal audit obligations continue to increase, security is becoming a matter of system integration. Individual solutions are no longer sufficient when traceability, response speed, and documentation are required simultaneously.

The combination of ZEUS® Access Control and the Security Monitor transforms fragmented security data into a centrally managed security ecosystem. For HR, IT, and security teams, this delivers not only greater transparency but also a reliable real-time basis for decision-making.

Greater transparency for HR, IT, and security management

This creates clear operational benefits for HR, IT, and security professionals. HR gains access to transparent access and movement data. IT benefits from a consistently integrated system landscape without information silos. Security teams gain significantly faster response capabilities.

Decisions are no longer based on the manual consolidation of individual data sources. Instead, they rely on a centralised and consolidated information environment that is available at all times and provides a reliable foundation for action.

When security isn't connected: data chaos vs. integrated control

Security area Typical standalone solution (Challenge) With ZEUS® Security Monitor + Access Control
Access events Logs are stored separately with no connection to alarms or video footage Access data is linked in real time with events and authorisations
Alarm notifications Individual alarms without context, requiring manual investigation Automatic assignment to people, locations, and time windows
Video surveillance Recordings exist without direct linkage to security events Video footage is correlated directly with access events and alarms
Response time Delayed due to system switching and manual analysis Real-time situational awareness significantly reduces decision-making time
Compliance (NIS2, KRITIS) Complex follow-up processes and fragmented evidence trails Comprehensive, centralised event documentation at the touch of a button
HR & IT collaboration Separate data sources and extensive coordination efforts A shared data foundation for employee and security information
