▶ Application

Road Traffic Control Centers are essential for the smooth-running of Traffic. To deliver an efficient service, managers face the issue of handling more and more surveillance cameras, PTZ cameras and live data feeds. Visualizing so many sources demands a flexible AV system which can display video in high quality and with minimal latency.  


The AV must also be able to monitor traffic reports from external agencies, including television news bulletins, so that Control Center personnel can assess emergent situations beyond the airport perimeter and make quick and informed decisions to deal with traffic jams and incidents. 


▶ Challenges

 • Numerous input sources including PCs, servers, notebooks, television decoder boxes and cameras 

 • Numerous displays, projectors and video walls 

 • Centralized management of all inputs  

 • High resolution/low compression live video with low latency   

 • Long-distance, cross-airport transmission 

 • Resilient 24/7 operation

 • Possibility for future expansion


▶ Solution Features

 • Easy to install

Long-distance cabling :
Decoders and encoders are connected to a network switch using standard 1m-100m cables. This means that the maximum transmission distance from the source encoder to display decoder is up-to 200m. This delivers long distance transmission at very low cost, using standard Ethernet cables. 

Flexible system architecture :  
By cascading multiple network switches, signals can be flexibly transported over a large area including across multiple floors of a property or between adjacent buildings.

 • Easy to use GUI

• Each feed can be previewed in a web browser making operation both accurate and intuitive 

• The GUI can run on any connected device, such as a laptop, smartphone or tablet 

• Source routing can be changed in real-time: drag-and-drop thumbnails quickly to switch sources and end points  

• Create monitor groups to apply layouts with a single click

 • High quality images 

High Quality 4K Transmission :
The Lumens 4K encoder/decoder pair (OIP-D50E / OIP-D50D) delivers 4:4:4 UltraHD video at 30Hz and 4:2:0 at 60Hz. Lumens' compression technology produces visually lossless 4K that can be transmitted over standard 1-Gigabit Ethernet networks.

Ultra-low Latency : 
With minimal delay between HDMI sources and decoders, 4K video can be sent dynamically to any display.

 • Low cost and easy to upgrade 

Flexible Solution :
Traditionally, when more sources and displays are added to an AV network, new matrix switchers may be required. Lumens' System is modular so can be expanded dynamically. It offers administrators the ability to add inputs (encoders) and outputs (decoders) individually, without the need to install and configure new matrix switchers.

Cost Efficiency : 
Because the Lumens AV over IP system is fully scalable, system expansion is simply a case of adding the encoders and decoders you need. This makes the OIP system very affordable, in terms of the initial investment, the cost of expansion, installation time and ongoing system management.
