Ethernet over Coax Transceiver

The Computar Ganz VHW-HW is a surveillance accessory that converts legacy analogue video cabling into a transparent 100BaseT Ethernet link. It allows installers to reuse existing coaxial infrastructure when upgrading to IP cameras. No IP addressing or configuration is required during installation. The unit fits inside camera housings for discreet deployment.

Installers upgrading legacy systems

This transceiver suits projects where coaxial cable is already in place and replacing it with new network cable is impractical. It supports multiple IP cameras, including Megapixel models, over a single coax run. Builders who need PoE delivery over the coax link should look at a different solution because the device draws power from the camera supply instead. Sites requiring fibre or wireless backhaul are also outside its scope.

100BaseT over 200 metres

The link operates at full 100 Mbps speed over coaxial cable runs up to 200 metres. This single specification determines whether the VHW-HW matches the bandwidth and distance needs of the camera deployment. If the installation demands Gigabit throughput or longer cable distances, this unit will not meet the requirement.

Questions about this item

Does the VHW-HW transceiver add noticeable heat or power draw when it runs continuously alongside an IP camera?

It draws very little power and can run from the camera's own supply, so extra heat and load are minimal during all-day operation.

What power source do I need to provide for the VHW-HW unit to function?

The transceiver operates from the camera's existing power supply; no separate adapter is required.

Will the VHW-HW work with the analogue coax cable already installed for my older cameras?

Yes, it transmits 100BaseT Ethernet over legacy analogue video cabling up to 200 metres.
