Product description
LR1002-1ET is a transmitter in Dahua Long Reach Ethernet over Coax (LR) system. Combined with the LR1002-1EC receiver, it converts the RJ45 connection to BNC, enabling long-haul data and PoE power transmission over a single coaxial cable. It is ideal for upgrading older CCTV installations based on coaxial cables without having to replace the cabling. The kit allows operation in two modes: 100 Mbps and 10 Mbps, automatically adjusting to the transmission distance.
Key features
- Long transmission range: up to 1000 m over RG59 cable.
- Flexible speeds: 100 Mbps up to 400 m, 10 Mbps up to 1000 m.
- PoE power supply: 48V passive, lines (1,2+ and 3,6-).
- Environmental resistance: operation from -30°C to +65°C.
- PLug & PL ay: automatic MDI/MDIX matching, no configuration required.
