Single Pair Ethernet for Elevator Connectivity

Connecting IP Camera and Intercom Systems in Elevator Cars with OmniConverter® Single Pair Ethernet Converters

Elevator systems are increasingly equipped with IP-based technologies such as surveillance cameras, intercoms, and monitoring sensors to improve passenger safety and building security. These devices require reliable data connectivity and power delivery within the elevator car, often under restrictive space and cabling conditions. Traditional Ethernet cabling can be bulky and difficult to install in elevator shafts or tight mechanical spaces.

Omnitron’s OmniConverter® Single Pair Ethernet (SPE) Converters provide an efficient solution, enabling the extension of IP-based security and communication devices in elevators using compact and costeffective two-wire single-pair cabling.

The Challenge

A property management company needed to upgrade the communication and surveillance systems in its elevator cars. The new system included IP cameras for security monitoring and IP intercoms for passenger assistance.

The challenges included:

1. Space constraints inside the elevator car and shaft, limiting the size of networking equipment.
2. Long cable runs, where conventional Ethernet’s 100-meter limit was insufficient.
3. Compatibility with both PoE and non-PoE devices (intercoms and cameras).
4. Ease of installation in a point-to-point application without the need for additional switches or bulky infrastructure.

Application Advantages

1. Extended Reach: SPE cabling supports distances up to 1000 meters, far beyond standard copper Ethernet limitations.
2. Smaller Cabling: Two-wire SPE cabling is easier to install in elevator shafts, saving space and cost.
3. Device Flexibility: Supports both PoE cameras and non-PoE intercoms.
4. Compact Design: OmniConverter devices are small enough to be mounted inside elevator control panels.

The Solution

The property management company deployed the OmniConverter 10BASE-T to 10BASE-T1L Converters, which feature:

• One IEEE 802.3cg compliant 10BASE-T1L (Single Pair Ethernet) port (IEC 63171 SPE connector).
• One 10BASE-T RJ-45 port (PoE or non-PoE).
• Compact, rugged design for installation in tight elevator control panels.
• PoE delivery capability to power IP cameras directly, while also supporting non-PoE devices such as intercoms.

The Result and Conclusion

After installation, the property management company successfully deployed IP-based cameras and intercoms in every elevator car. The OmniConverter SPE Converters provided:

• Stable point-to-point connectivity over long distances.
• Power delivery to PoE-enabled IP cameras without requiring external injectors.
• Simplified cabling and reduced installation time.
• A future-ready, standards-based infrastructure that can support upgrades.

By leveraging Omnitron’s OmniConverter Single Pair Ethernet Converters, the customer improved elevator safety, communication reliability, and security monitoring, while reducing installation complexity and costs.
