IP Intercom Systems for Critical Infrastructure
IP audio communication systems for industry, transport, healthcare, safety and emergency applications
IP intercom systems for critical infrastructure are a key component in modern audio communication networks where reliability, operational continuity and safety are essential requirements. Industrial facilities, transport infrastructures, public buildings, healthcare environments and strategic installations all need communication systems that remain immediately available even in demanding operating conditions or emergency situations.
ERMES InterLAN IP intercom systems are designed to operate on standard data networks, allowing native integration with existing LAN and WAN infrastructures while ensuring clear, stable and always-available audio communication. Thanks to a distributed and scalable architecture, these systems overcome the limitations of traditional solutions based on dedicated PBXs or central servers, reducing failure points and improving overall system resilience.
ERMES IP audio communication solutions are used in a wide range of contexts: industrial plants, rail and road transport installations, parking facilities, healthcare environments, public areas and high-criticality sites. In all these scenarios, IP intercom technology supports efficient management of operational, safety and emergency communications, helping improve control, response times and protection of people and assets.
InterLAN by ERMES is an advanced family of IP intercom devices compliant with the EN 62820 standard for intercom systems. The product range makes it possible to build reliable audio communication systems that are easy to use, easy to install and simple to expand or adapt over time.
IP intercom solutions for applications and industries
ERMES InterLAN IP intercom systems are designed to adapt to different application environments, ensuring dependable audio communication even in complex or high-criticality settings. Thanks to the modular structure of the platform, it is possible to design specific solutions according to the operating environment and the required level of safety, control and emergency support.

Standards and compliance
A key strength of the ERMES InterLAN range is compliance with the EN 62820 standard, which defines requirements for intercom and internal communication systems, particularly where safety or emergency applications are involved.
In public or industrial projects, using EN 62820-compliant devices helps designers and integrators develop systems in line with current best practice, facilitating project qualification and alignment with technical rules and regulations for critical environments.
Compliance also reflects a robust level of construction and functional quality. InterLAN systems are designed for long-term operation, high audio intelligibility, and dependable performance in everyday use as well as in demanding field conditions.
Peer-to-Peer architecture: direct, reliable communication
One of the distinctive features of the InterLAN system is its Peer-to-Peer (P2P) architecture. Devices in the range are natively IP-based and connect directly to the data network, communicating point-to-point without the need for a central server. In practice, every unit is a stand-alone device capable of handling calls autonomously, avoiding the need for dedicated PC software or telephone exchanges to route communications.
The main benefits of the P2P approach are:
-
High reliability:
In ERMES communication systems, the absence of a single central element for call routing greatly improves overall resilience and reliability. In a distributed architecture, each intercom can continue to operate autonomously, which means the system remains available even if one device becomes temporarily unavailable or a local issue occurs.
Direct communication between intercom stations, without intermediate routing nodes or centralised call servers, helps maintain fast and dependable contact paths. This design is especially valuable in high-criticality sectors where operational continuity and immediate voice communication are essential.
-
Scalability and flexibility:
Adding a new InterLAN station is as simple as connecting it to the system LAN. Once an IP address is assigned, the unit can be configured to call the required stations directly. With no central server to reprogram, expanding or modifying the system is fast, practical and cost-effective.
Point-to-point calls can be configured between specific intercoms, while call groups can be defined for particular zones through straightforward software setup. Each device can be programmed so that a button triggers a call to a dedicated operator station or activates a communication path configured for the application.
-
Simple installation and integration:
The P2P technology used by InterLAN is fully based on TCP/IP standards, which means the intercom units can run on the existing data network without requiring proprietary infrastructure. There is no need for dedicated special cabling: the standard Ethernet network of the building or plant is sufficient.
Many devices can also be powered via PoE (Power over Ethernet), reducing wiring complexity and simplifying deployment. These characteristics make installation easier and help integration into complex systems where IP intercom functions need to coexist with other technologies.
In short, the Peer-to-Peer architecture of InterLAN enables direct, immediate and robust communication between all system points, providing a secure and scalable platform for mission-critical audio communication needs.
Benefits for designers, contractors and system integrators
Choosing the InterLAN range also brings practical advantages to professionals who need to design, integrate or maintain the system.
Serverless simplicity
The Peer-to-Peer structure eliminates the need to install and maintain central servers or dedicated call-management PBXs.
That means fewer components, lower initial complexity and easier configuration.
Compatibility with existing infrastructures
InterLAN integrates easily into the customer's data network using standard Ethernet switches and PoE, making it suitable both for new projects and retrofit applications.
Modular growth over time
New stations can be added without redesigning the full system architecture, making the platform suitable for infrastructures that evolve in phases.
Unified technology across different applications
The same ERMES IP communication approach can be used across industrial, public, healthcare and transport environments, simplifying specification and technical support.
