Veracity Highwire VHW-HW Ethernet Over Coax Converter

The Veracity HIGHWIRE is the ultimate solution for upgrading to IP-based surveillance systems while utilizing existing coaxial cabling. It enables you to connect a IP cameras over a single coax cable, making it perfect for camera installations in legacy systems. HIGHWIRE turns any existing analogue video cable (coax) into a high-speed Ethernet connection. This allows a networked IP camera to replace an analogue CCTV camera, without installation of any new cabling. Thus the investment in the original cabling (usually around 30% of any system installation cost) can be retained and exploited for new-generation networked IP camera systems. 

HIGHWIREs are used in pairs and installing them is extremely simple. One HIGHWIRE unit is connected to each end of the co-axial cable with the BNC connectors, thus providing a straight RJ45 to RJ45 network connection from end to end across the existing cabling. A HIGHWIRE to HIGHWIRE connection instantly operates as a full-duplex 100Base-TX Ethernet connection and is completely transparent to any network device. HIGHWIRE has no MAC address or IP address and requires no set-up at all.

This HIGHWIRE unit is the receiver that is installed at the camera end. You will also require the base unit which can be found here.

Application
In the application shown below, a high-resolution mega-pixel IP camera replaces a standard analogue CCTV video camera. The IP camera’s standard Ethernet TCP/IP connection is linked to a HIGHWIRE device with a short CAT5 patch cable (straight through or cross-over). Both the camera and the HIGHWIRE are powered from the same power supply, and both may be fitted inside a standard external camera housing. The HIGHWIRE link runs across the existing installed 75ohm co-axial video cable, and the rest of the network is connected at the other end (normally the control or equipment room). One, several, or many such links may feed into the network to an NVR. As the network link is full speed and fully transparent, the IP camera appears on the network as a completely normal IP connection.
The NVR will “see” the IP address of the IP camera as if it were a normal direct Cat5 connection

Although designed for IP video, the HIGHWIRE connection is a universal 100Base-TX network link that can be used for any application. Any legacy coaxial cable can be used, or new coaxial cable can be installed, to deliver an extended network that’s a rugged, low-cost alternative to fibre. Although designed for 75ohm cable, HIGHWIRE can operate over 50ohm cable with full performance with only a slight reduction in the maximum distance attainable.
