The DTV-IPCOAX/R is Ethernet and power signal receiver over single coaxial cable. The DTV-IPCOAX/R is used with DTV-IPCOAX/T, which is an ideal solution for reconstruction of old projects without any change of existing coaxial cable. You needn't change coax into network cable when you want to change analog cameras into IP cameras. Both of Ethernet and power transmission distance reach max up to 1000 meters. With high speed modern technology, the physical bandwidth is up to 100Mbps (bidirectional). The DTV-IPCOAX/R is built-in multi-stage surge and lightning protection protect video equipment against damaging voltage spikes and provide noise immunity to ensure quality signals without disturbing "hum-bars". The DTV-IPCOAX/R is widely applied to the fields such as network expanding system, network security system, network information distribution system, network upgrading & expanding system, railway and urban transportation, metallurgy and mining, field operations, etc.
