Nine essential commercial building security system features

The sections below will explore the nine essential commercial building security features. 

Intrusion detection

Commercial buildings have intrusion detection systems (IDS) to detect and report intrusions during non-business hours. The common types of sensors used in an IDS include:

  • Motion sensors: These use passive infrared (PIR), ultrasonic, and microwave technologies, often combined in dual-tech and tri-tech configurations, to detect motion.
  • Contact-based sensors: Use reed switches to monitor the opening and closing of entry and exit points, such as doors and windows.
  • Vibration/shock sensors: Use piezoelectric materials to sense vibrations or mechanical stress, detecting potential tampering or forced entry.
  • Glass break detectors: Detect the sound and vibrations associated with breaking glass, providing an early warning of potential breaches.

These sensors use an alarm panel to detect, interpret, and report suspicious activities. 

Video surveillance

Technological advancements have led to sophisticated CCTV systems that enable proactive rather than reactive monitoring. Modern systems generate alerts for exceptions such as unattended baggage, blacklisted individuals, and the presence of weapons, promptly notifying security personnel. Key technologies used in these systems include:

  • Automatic Number Plate Recognition (ANPR): This is used in applications requiring rapid vehicle identification and monitoring. ANPR uses advanced image processing and ML to capture and analyze vehicle plates. A cloud-based IoT management platform will enhance real-time monitoring across various security systems.
  • Facial recognition: Uses image processing and AI to enable seamless monitoring and intelligent search.
  • People counting: Systems that use advanced video analytics within CCTV to track and quantify foot traffic by detecting, identifying, and distinguishing individuals in real time. It is used in various business premises for security and operational optimization.
  • Intrusion detection: Predefined zones with a set minimum and maximum target size, time threshold, and sensitivity can detect unauthorized movement or activity.
  • Region entrance and exit monitoring: Using analytics and alerts to track the movement of personnel and vehicles into and out of designated zones.
  • Line crossing detection: Using virtual boundaries to trigger an alert when an object crosses a set direction. This is predominantly used for perimeter protection.
  • Behavior analytics: Automates the detection of suspicious activities by analyzing patterns in real-time video feeds.

The features discussed can be applied in various scenarios in commercial buildings to enhance the efficiency and effectiveness of video surveillance.

Advanced access control

Access control systems control, monitor, and log access into and out of restricted areas. They can be categorized into human and vehicular access control. Both categories can have a supplementary security measure that introduces the ability to manage and verify entry into a restricted area. The supplementary security measures are intercom and visitor management.

Vehicular access control

These have evolved significantly with advancements in physical security technologies. Automated boom barriers, often integrated with RFID readers, license plate recognition (LPR), or access cards, efficiently control vehicle entry and exit. Barrier gates, designed to withstand impact, are typically used at high-security locations and are integrated with access credentials for secure entry. Retractable or fixed bollards prevent unauthorized vehicle access and are controlled via remote systems or integrated with access control platforms. Recent advancements have introduced IP-based vehicular access control devices, allowing them to be managed, monitored, and controlled on a CMS via the IT infrastructure.

Human access control

Facial recognition technology provides a contactless biometric solution that scans and verifies facial features to grant or deny access. Iris reading is another advanced biometric solution that scans the unique patterns in a person’s iris for authentication. Fingerprint scanning remains a standard biometric method that uses unique fingerprint patterns to authenticate users. Additionally, other biometric technologies, including voice recognition, palm vein scanning, and multimodal biometrics, offer diverse options for securing human access to commercial buildings.

Intercom and visitor management

These systems facilitate communication between entry points and security personnel or tenants. Video and audio intercoms, now often IP-based, are integrated with visitor management systems to register and track visitors efficiently. Their integration with cloud-based platforms allows for remote opening of doors and gates from mobile devices, enhancing convenience and security.

Centralized management

Deploying a central management system (CMS) in commercial buildings is critical to ensuring interoperability among individual components such as IDS, CCTV, fire alarms, and access control systems. The CMS uses analytics to provide features like device health monitoring, batch configurations, and firmware upgrades, ensuring seamless integration and efficient management of all security components.

Stability and resilience 

The deployment of a commercial building security system must be able to accommodate growing requirements, include redundancy for reporting and connectivity, and enable remote monitoring of device health statuses.

Scalability

The security systems should be able to grow and adapt to increasing demands by using modular components like cameras and sensors, integrating with existing IT infrastructure, and utilizing distributed processing and cloud-based solutions. They ensure performance and reliability through seamless integration, flexible configurations, and robust network protocols like ONVIF, RTSP, and BACnet, which support evolving security needs and handle large data volumes and complex analytics.

Reliability and redundancy

This involves implementing robust failover mechanisms and backup solutions to maintain operational integrity in the event of component failures. Systems should include dual power supplies, redundant communication paths, and fail-safe modes for critical components like alarm panels and cameras. Additionally, data should be regularly backed up to secure, remote locations, preferably cloud-based servers, to prevent loss from hardware malfunctions or cyber incidents. Designing for high availability with these redundancy features minimizes downtime and maintains consistent security coverage, even during system maintenance or unexpected failures.

Health monitoring

Health monitoring supports system reliability and optimal operation, allowing users to identify and address potential issues proactively. Modern security systems utilize existing internet infrastructure within commercial premises to enable remote health monitoring. One of the key features of health monitoring is the presence of tools for managing firmware and software updates to keep devices secure and up to date.

Integration capabilities

Integration with building management systems, IT infrastructure, and other security systems is important for seamless operation. Physical Security Interoperability Alliance (PSIA) allows unidirectional data flow between IP-enabled security devices, enabling functionalities such as:

  • Infrastructure Video as a Service (IVaaS): a cloud-based video surveillance solution enabling security personnel to verify alarms visually before dispatching response teams. It integrates video surveillance with alarm systems to enhance response efficiency.
  • Access control door release in emergencies: This system is designed to ensure egress during emergencies such as fire. The doors are operated via electromagnetic or electric strike locks controlled by relays or fire alarm panels.
  • Lighting control and automation: This is based on occupancy as determined by the access control system or, in other instances, schedules based on real-time data from security sensors.
  • Elevator automation: typically uses key cards, biometrics, and PIN codes to restrict access to specific floors. This integration ensures strict control and monitoring of movement within the building.

This feature enhances overall efficiency and responsiveness in commercial building security.

Data analytics

The systems should make use of the collected data to enhance operational efficiency and predict potential threats. These analytics can identify anomalies, predict suspicious activities, and optimize response protocols by looking at patterns in video surveillance, access logs, and intrusion detection systems. This process assists in improving security measures, reducing the time spent on incident response, and adapting to evolving security needs. Advanced data analytics are necessary to proactively implement threat management and system performance optimization.

Compliance with standards

Ensuring adherence to established standards, such as ISO/IEC 27001 for information security and local fire and safety codes, guarantees that the security system can safeguard the confidentiality and integrity of sensitive data and physical assets. It involves implementing best practices for system design, maintenance, and operation and regular audits and updates to align with evolving regulations and industry benchmarks. This compliance supports system integrity, facilitates seamless integration with other building management systems, and ensures operational consistency.

Cybersecurity measures

Modern commercial building security systems must help organizations address cybersecurity risks. Here are seven security measures that commercial building security systems should provide: 

  • Strong encryption for data in transit and at rest: Cleartext protocols make it easier for attackers to sniff packets and capture sensitive data. Security systems should use encrypted protocols (e.g., HTTPS, TLS 1.2 and 1.3) to reduce the risk of data leakage. Similarly, encrypting data at rest reduces the risk of sensitive data exposure even if a threat actor breaches a system. 
  • Multi-factor (MFA) authentication for system access: Implementing MFA can significantly reduce the risk of security device compromise. Organizations should enforce MFA for connected security devices wherever practical. 
  • Network segmentation: Strong network segmentation can reduce attacker east-west movement in the event of a breach, help enforce the principle of least privilege, and decrease the chances of an IT network compromise leading to a compromise of security systems. 
  • Regular update firmware: Firmware updates may include critical security patches for vulnerabilities threat actors target. Given that many attacks on “smart” devices attempt to exploit known vulnerabilities applying firmware patches can reduce the risk of a breach. For example, many camera vulnerabilities that can be addressed with a firmware patch. 
  • Vulnerability assessments: Regular vulnerability assessments enable organizations to detect and address cybersecurity issues that can emerge over time. 
  • Threat detection: Intrusion prevention functionality can help detect threats and enable incident response for unauthorized access.
  • Access logs: Unusual access attempts are a key indicator of potential attacks. Monitoring access logs for anomalies can help teams stay a step ahead of an attacker or perform root cause analysis in the event of a breach.
