PoE Ethernet Extender Transmitting up to 800ft Transmit Both Data and Power Over One Coaxial Cable for PoE IP Surveillance CCTV Cameras Supports IEEE 802.3af & IEEE 802.3at; Transmit 250m at 10Mbps and 150m at 100Mbps Install New IP Cameras Using Existing coaxial Cable, Compatible with RG59/RG6 Coaxial Cable User Friendly Easy Plug-n-Play, No Power Adapter Needed This Mini-Power kit is the most economical PoE over Coax Solution. By using novel technology, PoE signal can be converted into coaxial cable with a transmitter. After passing through the remote receiver, PoE signal will be converted back to Ethernet signal. Unlike regular EoC adapters require additional power for the IP cameras, the receiver can retrieve power from PoE signal without local power injection, so no power adapter is required. It is compatible with IEEE 802.3af & 802.3at and provides with more than 30W / 0.75A PoE power through RG59 coaxial cable. The transmission distance over RG59 coax is up to 250m (820 ft) at 10Mbps and 150m (490 ft) at 100Mbps respectively.
