Australia Bridge Uses Infinova Fiber Optics To Link Cameras
Infinova recently announced that the West Gate Bridge in Melbourne, Victoria, Australia is using Infinova’s fiber optics solutions to link cameras on the bridge to the City of Melbourne video depot. The bridge is the third longest in Australia with a total length of 2,582 m (8,473 feet).
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.
