Seco Larm ne-se01-020q Ethernet Over Coax Extender 650 Ft

Product Description

The SECO LARM ne-se01-020q is a passive Ethernet extender that transmits TCP/IP signals over existing coaxial cable, pushing network connectivity beyond the standard 330-foot (100-meter) Ethernet distance limit up to 650 feet. No external power supply is required for the passive design, and no software configuration is needed. The unit passes all protocols, codes, and applications without filtering, making it suitable for IP camera deployments and other networked devices operating at 10/100 Mbps. Security integrators and low-voltage technicians install this device where running new Cat5e or Cat6 cable is impractical but coax is already in place.

This extender is well suited for retrofitting existing coaxial cable infrastructure in residential and commercial installations. Typical applications include CCTV-to-IP camera upgrades, where existing RG59 or RG6 coax runs are repurposed for Ethernet connectivity. Any TCP/IP device that falls within the supported network speed range can operate over the extended link without modification to its software or firmware.

Key Features

• Passive design requires no external power source
• Extends Ethernet over coaxial cable up to 650 feet
• Supports 10/100 Mbps network speeds
• No protocol filtering — passes all TCP/IP traffic transparently
• Compatible with IP cameras and their native software without modification
• Leverages existing coax infrastructure, reducing new cable installation costs

Compatibility

Designed for use with any TCP/IP device, including IP cameras and networked equipment operating at 10/100 Mbps over coaxial cable runs up to 650 feet.

Installation Notes

Installation is typically performed by licensed low-voltage or security technicians. Power down or disconnect the network switch port before connecting the extender to avoid signal conflicts. Ensure coaxial cable connectors are properly terminated and free of corrosion before installing the unit. Follow local low-voltage wiring codes and the NEC where applicable.
