The ET1500CB is another component of the Nitek cutting edge Etherstretch™ line developed for the Offshore, Oil and gas Industry. This Environmentally Hardened Etherstretch™ solution allows for the utilization of existing cable infrastructure to transmit data from IP cameras and other network devices over the wire for distances up to 500 meters or 1.640 feet.


The ET1500CB is part of an overall system. The transmitter works in conjunction with a multiport receiver and requires very little installation time and no set up or configuration. These units quickly turn ordinary RG59 coax cable into a high speed network communication for distances up to 500 meters or 1.640 feet. The ET1500CB is transparent to the network thus requiring no IP and MAC addressing. Simply connect your network devices to the networking ports of the transmitter and receiver along with existing cabling and the system begins communicating. LED indicators show the status of network communication. The ET1500CB requires no network settings to be changed or adjusted. The Nitek Etherstretch ET1500CB extends network communications to overcome cable distance limitations offering connections to devices in locations traditional networking does not allow. The ET1500CB is ideal for retrofitting existing installations. The unit is constructed of industrial grade RoHS compliant plated aluminum which is finished with a corrosion resistant finish making it very durable.
