Dahua’s patented Enhanced Power Over Ethernet (ePoE) product line offers cameras, switches, and NVRs which can be used as standalone PoE ONVIF devices, as a combined solution for increased distances over UTP without repeaters or as part of a solution to convert existing coax (RG59) into a pure IP infrastructure via Dahua’s EoC passive media converters and ePoE devices.

ePoE is the industry’s most flexible line of devices that have the ability to change when you do.

Key Benefits


ePoE technology provides an eco-friendly security solution that helps conserve energy to reduce your carbon footprint. Using only one Ethernet cable to span 800 m (2624  ft) without the need  for extra switches saves about 182.5 kWh per year.


ePoE technology delivers immediate cost-savings by reducing the number of devices required to connect each front-end device to the back-end. ePoE systems require less devices, use cheaper Ethernet cabling (as compared to fiber), and takes advantage of existing infrastructure saving installation cost and time.


ePoE technology uses advanced modulation to transmit video, data, and power up to 800 m (2624 ft) at 10 Mbps via a single CAT5E cable  between  an IP camera and a PoE switch or NVR.


Ethernet over Coax (EoC) technology delivers a simple and cost-effective solution with plug-and-play installation that reduces the costs of upgrading from analog to IP cameras. Easy to use converters allow the transmission of video, data, and power over existing coaxial cabling between an IP camera and a PoE Switch or NVR.

ePoE technology delivers the best of both Network & Coax worlds.

Dahua ePoE IP systems support a range of up to 800 m (2624 ft) between the ePoE camera and the ePoE network switch or ePoE NVR. This surpasses traditional Ethernet and PoE limitations (both restrict cable distances to 100 m (328 ft) between network ports) and eliminates the need for Ethernet extension devices or additional network switches. This significantly lowers costs as less cables and repeaters are required, and the system takes less time to install.

The Dahua ePoE system is an eco-friendly surveillance system that uses only one cable to connect from front-end to back-end devices. With an EoC Passive Converter (LR1002) which connects to the Ethernet port of an IP camera or network switch on one end and a coaxial cable on the other, analog systems can be easily upgraded to use IP devices while reusing existing coaxial cables. This is a simple and effective solution that delivers seamless plug and play installation, significantly reducing the cost of upgrading from analog to IP.

New Installation Advantages

Dahua’s proprietary ePoE technology provides a lower cost of ownership to users who want longer transmission distances without interruption. Transmitting up to 800 m (2624 ft) without repeaters, ePoE technology makes applications with long distance requirements more affordable. Additionally, ePoE devices are backwards-compatible with standard Ethernet devices, giving you flexibility no matter what your system requires.

Enhanced PoE network camera devices extend connectivity beyond the IP standard distance of 100 m (328 ft) while providing integrated power to the device.

Retrofit Advantages

Dahua’s ePoE technology has the ability to convert coax cabling to a full IP solution. Users who want to migrate to IP don’t have to rip and replace cables. Additionally, longer distances can be achieved compared to standard IP devices.

Power over Coax (PoC) simplifies installation, eliminating the need for a separate power supply cable when reusing coax.

Dahua’s Ethernet over Coax technology offers a flexible and cost-effective system to seamlessly upgrade a coaxial infrastructure to a pure IP solution. EoC delivers long-range data and power transmission, eliminating the need for separate power supply cables and costly cable replacement. EoC is a simple and effective solution that delivers seamless plug-and-play installation, significantly reducing the cost of upgrading from analog to IP. The following charts illustrate the connection details to upgrade an analog system using Dahua’s ePoE devices, traditional PoE devices, or a combination.

Two LR1002 Passive Converters directly converts between Ethernet and coaxial signals to transmit power and data over a coaxial cable between two ePoE-enabled devices, leveraging existing analog infrastructures.

An LR1002-1ET EoC Transmitter connects a traditional PoE-enabled IP camera to an ePoE switch/ePoE NVR via a coaxial cable leveraging existing IP cameras and extending their reach.

An LR1002-1EC EoC Receiver connects a traditional PoE-enabled switch or NVR to an ePoE camera via a coaxial cable leveraging existing PoE back-end equipment and extending their reach.

An LR1002-1ET EoC Transmitter and an LR1002-1EC EoC Receiver convert an existing traditional PoE system into a long-distance ePoE system, transmitting power and data signals over an existing analog infrastructure.
