IP Video 2 Wire Network Extender: 16 Port Receiver Unit

The Nitek ER1651U is another component of the NITEK cutting edge Etherstretch™ line. The ER1651U Receiver cambined with an ET1551U Transmitter (sold separately) provides a solution that utilizes existing 2 wire UTP cable infrastructure to transmit data from IP cameras and other network devices. The ER1651U/ET1551U combination can extend Ethernet range up to 500 meters over a single pair of wires.

Surge protection system IPPWR16 is recommended in applications with outdoor transmitters.

The ER1651U is a multi-port unit that can provide extension of Ethernet for up to 16 IP video cameras and network devices. An internal Layer 2 Switch with a Gigabit LAN connection, operates in conjunction with the ET1551U transmitter units. Using the ER1651U over any ordinary Twisted Pair cable for a distance of 500 meter requires no additional equipment other than the new ET1551U transmitter(s).

This New Etherstretch™ system requires very little installation time & no set up or configuration. The system is completely transparent to the network with no IP or MAC addressing required. Simply connect a network device to the transmitter. LED connectivity indicators on the transmitter and receiver show the status of network communication and PoE power. The ER1651U Etherstretch network extender overcomes cable distance limitations inherent in traditional networking topologies and provides an alternative to fiber or wireless transmission solutions.

ER1651U features include:

  • Rack mounted multi-channel 2 wire Etherstretch solution
  • Each channel is capable of 10/100 connectivity to field devices
  • Gigabit output to network
  • Remotely transmit IP devices over 2 wire network category cables up to 500 meters/1,600 feet
