Australia’s West Gate Bridge using Infinova Fiber for CCTV comms

 

Another Successful Project...

All equipment by Infinova, installed on the West Gate Bridge in Melbourne, Australia were proudly supplied by Security Merchants Australia Pty Ltd.

INFINOVA says the West Gate Bridge in Melbourne, Australia, is using its fiber optics solutions to link cameras on the bridge to the City of Melbourne’s video control room. The bridge is the third longest in Australia with a total length of 2582m.
“This bridge is just one of many major infrastructure projects which have turned to Infinova fiber optics for more efficient, quality transmissions of images,” reports Mark S. Wilson, Infinova vice president, marketing. “Since high-performance surveillance systems require greater reliability and increased throughput, the leaps forward in CCTV system technology have increased the demand for Infinova fiber optics.”

 To assure duty officers can maintain smooth flowing traffic and react immediately to a crisis on the bridge, an Infinova N3731 Series fiber optics transmitter, which provides the ability to transmit one digitally encoded video channel with bi-directional RS-232/RS-422 contact closure and DIP selectable data (RS-422/RS-485/Manchester/Biphase) over one or two fibers, is mounted on the West Gate bridge.  

It receives video from the PTZ dome camera on the bridge and then transmits the video to the West Gate Bridge Depot via fiber. Another N3731 Series transmitter collects the video at the Depot. The fiber optics units can be rack-mounted or used as stand-alone modules, placed on a desktop or mounted to a wall.

 Meanwhile, all videos received from the bridge are distributed to an Infinova N3790 Series transmitter for transmission over a single fiber to Melbourne City for remote monitoring. At the same time, the N3790 Series transmitter sends PTZ control data to the dome cameras via fiber. As a result, duty officers that are kilometers away can view and control the PTZ control function of the cameras on the bridge.

 The N3790 Series fiber transmitter is a digitally encoded, highly expandable and flexible fiber optics transmission system. Data formats support RS-232, RS-422, 2-wire/4-wire RS-485, Manchester/Biphase and contact closures. Using state-of-the-art CWDM technology, they transmit up to 64 channels NTSC, PAL, or SECAM video, 32 channels audio, 32 channels data, 32 channels contact closure signal or eight channels intercom.
