HIGHWIRE Ethernet speeds up data transmission
It’s the age of superior digital video surveillance, where security professionals expect nothing less than the crystal-clear imagery and detailed information of mega-pixel technology.
Yet, says Francois Smuts, New Business Development Manager for Elvey Security Technologies, with mega-pixel surveillance producing 100 times more data than conventional systems, the transmission of such high quality signal often presents major problems.
He’s therefore enamoured with a new product called HIGHWIRE, which has been designed to bridge the transmission gap. “HIGHWIRE turns any existing analogue video cable (co-ax) into a high-speed Ethernet connection,” he explains. “This allows multiple networked IP cameras to replace a single analogue CCTV camera without the installation of any new cabling.”
Financially and time-wise, this is good news for anyone with a legacy system, considering that cabling tends to account for 30% to 40% of the installation costs, he points out. “HIGHWIRE, which allows existing cabling to be retained and exploited for new-generation, networked CCTV (closed circuit television) camera systems, is especially well suited to mega-pixel IP camera applications or multiple IP cameras, owing to its ability to support high data rates.”
HIGHWIRE makes it possible to operate to a maximum of 300 meters, with full speed at 200 megabit per second at 200 meters of coaxial video cable, which means entities are able to maximize the potential of their IP (internet protocol) cameras. “It’s therefore ideal for organizations wanting to connect buildings, provide Internet to distant security locations or increase the safety and security of their personnel through the use of mega-pixel camera technology,” he avers.
In addition to its money-saving implications, it’s also simple to install. According to Smuts, this is because HIGHWIREs are used in pairs. Connected to each end of the co-axial cable, they provide a straight network connection from end to end across the existing cabling. Since HIGHWIRE has no MAC or IP address, there is no set-up requirement whatsoever, he notes further. What’s more, if the co-axial cable is of poor quality, longer than the recommended distance or suffers from signal interference along its installed path, the two HIGHWIREs will auto-adapt to the signal transmission conditions and lower the total bandwidth where necessary.
