High Speed Ethernet Extender W/PoE - Up To 2,500 Feet (750 Meters) Over Coax

The Nitek High Speed Ethernet Extender VR148COAX Network Extender-PoE Inserter allows IP Ethernet transmission of network data to communicate over an existing coaxial cable for distances up to 2,500 feet (750 meters). In addition, the transmitter will convert the 24VAC used to power standard analog cameras to PoE for the installation of the new IP cameras.

The VR148COAX Ethernet Extender over Coaxial Cable-with PoE Inserter consists of a transmitter and receiver set which requires very little installation time and absolutely no set up or configuration. Installation requires simply connecting the BNC connectors at each end of the existing coaxial cable to the transmitter and receiver of the VR148COAX. Once powered up the transmitter will produce PoE for its connected device. The receiver instantly connects to the transmitter and begins operating as a full-duplex 100BaseT Ethernet conduit. The VR148COAX Ethernet Extender over Coax is completely transparent to the network; it has no IP or MAC addresses and does not require any additional setup or programming. Connect your network devices by plugging their RJ45 connectors into the network port of the transmitter and receiver. LEDs on the devices indicate the presence of power, transmission link and network signals for easy troubleshooting.

The VR148COAX Ethernet Extender-PoE Inserter extends network communications to overcome cable distance limitations offering connections to devices in locations traditional networking does not allow. The VR148COAX will auto-negotiate bandwidth to compensate for wire attenuation and losses that occur from wire length, signal noise and interference. (Please refer to cable distance and bandwidth charts for further review).

The units are constructed of industrial grade RoHS compliant plated steel which is finished with a heat resistant powder coat paint making them very durable. They are designed to mount within the camera housing, in an equipment enclosure or simply wall mount the unit using the included mounting kit. For installation of several units the RK124 rack mount kit allows for centralized power of the receiver units while maintaining an orderly installation.
