Network receiver Dahua Technology LR1002-1EC-V3 10 100 Mbit/s Grey

The Dahua Technology LR1002-1EC-V3 network receiver provides wired data transmission over long coaxial runs and standard Ethernet cabling. It supports 10/100 Mbit/s Ethernet (10/100Base-T(X)) and is compatible with IEEE 802.3 and IEEE 802.3u standards. The compact grey unit includes one RJ45 10/100Mbps port and one BNC connector, and is designed to support data and PoE power delivery over coaxial cable up to distances of 400 m at 100 Mbps and up to 1000 m at 10 Mbps. Physical dimensions are 79 × 52 × 23 mm and maximum power consumption is 2 W.

Advantages

The LR1002-1EC-V3 combines Ethernet-to-coax conversion with PoE support to enable network and power transmission over RG59 coaxial cable, allowing deployment where long cable runs are required. It supports MDI/MDIX auto-adaptation for simplified connection and provides a compact, low-power solution (2 W) with a single RJ45 port and BNC interface suitable for integrations with surveillance and network devices.

Suitable for

• Extending network links over RG59 coaxial cable for CCTV and legacy cabling
• Supplying data and PoE to remote network devices where twisted-pair cabling is impractical
• Integrating IP cameras or network receivers at distances up to 1000 m (10 Mbps) or 400 m (100 Mbps)

How to use

Connect the BNC connector to the RG59 coaxial cable run and the RJ45 port to the network device. Ensure correct pairing for PoE power delivery over the specified data line pairs (1, 2, 3, 6). Verify link speed after connection; at longer coaxial distances the link may negotiate at 10 Mbps to maintain stability. Mount the unit in a dry, ventilated location and observe polarity and connector seating to prevent signal loss.

Recommendations

Use RG59 coaxial cable in good condition and verify cable length and quality when planning installations; for 100 Mbps operation keep coax runs within 400 m. For stable PoE delivery, confirm compatibility of connected devices and follow local safety and grounding practices.
