ePoE - a standard for data and power transmission over UTP and coaxial cable
ePoE standard allows to supply power to the IP camera via a compatible network switch or NVR with embedded switch at the distance of up to 800 m (to overcomes the limitation of traditional Ethernet restricting cable distances to 100 metres). |
The standard allows to transfer power over Ethernet at the distance of up to 800 m - 13 W power input at 10 Mb/s or at the distance of up to 300 m - 25.4 W power input at 100 Mb/s. |

A solution patented by Dahua also allows to connect the IP cameras with coaxial cables with EoC LR1002 ePoE to BNC adaptor. The maximum transmission distance using RG-59 cable is 1000 m (at 10 Mb/s and max. 8 W power input). Table 1 shows available ePoE range using RG-59 cables. |

ePoE technology offers data and power transmission at significant distances over coaxial and UTP cables. It offers more flexibility and reduces the rewiring costs. |
