Overview
IEC 62820-1-2:2026 is an international standard that defines system requirements for building intercom systems using Internet Protocol (IP). Developed by the International Electrotechnical Commission (IEC), this standard provides comprehensive technical requirements covering the composition, functionality, performance, and testing methods for IP-based intercom systems installed in both residential and commercial buildings. It serves as a supplement to IEC 62820-1-1 and addresses the specific needs and challenges of implementing IP communications for modern building intercom solutions.
Key Topics
- System Composition: Defines the structural components needed for IP building intercom systems, ensuring interoperability and reliable communication between devices.
- Functional Requirements: Covers both basic and enhanced functionalities such as bidirectional audio/video communication, messaging features, and remote configuration capabilities.
- Performance Criteria: Establishes benchmarks for audio and video quality, including loudness, echo adaptation, latency, switching times, image resolution, refresh rates, and synchronization between audio and video streams.
- Security Provisions: Specifies controls for network access and data integrity to protect against unauthorized access and ensure the confidentiality and reliability of transmitted information.
- Testing Methods: Outlines laboratory conditions and methodologies, including objective and subjective evaluations of audio/video performance and security features, to certify compliance with the standard.
Applications
The adoption of IEC 62820-1-2:2026 is essential for:
- Residential Buildings: Facilitating secure and reliable door communication, visitor identification, and access management for apartments, condominiums, and gated communities.
- Commercial Properties: Supporting communication and security in offices, schools, hospitals, hotels, and public buildings by integrating with broader security and building management systems.
- Remote Management: Enabling advanced functions such as offsite device monitoring, configuration, firmware updates, and secure video/image storage.
- System Integration: Ensuring compatibility between intercom devices, including audio and video units, call panels, and security management units across IP networks.
- Quality Assurance: Providing a framework for manufacturers and service providers to assess and validate the operational quality and security of their IP-based building intercom products.
