Dahua Ethernet Over Coax Extender Receiver
The Dahua LR10021EC is a single-port Ethernet over coax receiver designed to extend Ethernet data and power over existing RG59 coaxial cable. It is typically used at the camera end of an Ethernet over coax (EoC) link and pairs with a compatible Dahua transmitter to reuse legacy coax infrastructure for Internet Protocol cameras.
Key Features
- Extends Ethernet data and power over RG59 coaxial cable.
- Supports transmission distances up to 400 m at 100 Mbps and 1000 m at 10 Mbps.
- Power over Ethernet support in accordance with IEEE 802.3af and IEEE 802.3at.
- Automatic Medium Dependent Interface and Medium Dependent Interface Crossover (MDI/MDIX) adaptation.
- Compact, low-power design suitable for camera-side installation.

Frequently Asked Questions
- Does this work on its own?
No. This receiver must be paired with a compatible Dahua Ethernet over coax transmitter to form a complete link. - Can it power an Internet Protocol camera?
Yes. When used with a compatible transmitter and power source, it supports Power over Ethernet in accordance with IEEE 802.3af and IEEE 802.3at. - What type of coax cable is required?
It is specified for RG59 coaxial cable. Performance and distance may be reduced with other cable types.
Additional Information
- This receiver is commonly installed at the camera end of the run, with the transmitter located near the network switch or Network Video Recorder.
- Longer cable runs reduce available PoE power. Always check camera power requirements against distance tables before finalising design.
- Performance figures are based on RG59 coax with controlled impedance. Poor-quality or damaged cable can significantly affect results.
