IP Video 2 Wire Network Extender

The Nitek EL1551U is a transmitter-receiver system which extends 100Mbps of Ethernet communication over a single pair of communication wires up to 1,500 ft (460 meters). The EL1551U is a component of the NITEK cutting edge EtherStretch™ product line that turns any ordinary pair of wires, such as UTP or any 2 conductor cable into a high speed network communication path. The system is transparent to the network and requires very little installation time, with no setup or configuration needed. Simply connect your network devices to the network ports of the transmitter and receiver along with existing cabling and the system begins communicating.

The EL1551U system is ideal for upgrading analog UTP video balun systems to IP systems without needing to replace or even disturb the existing cable infrastructure. Power is provided to the ET1551U transmitter from the ER1551U receiver unit. LED indicators show the status and speed of network communications.
