MANAGING DISASTERS WITH LED VIDEO WALLS

The news of Hong Kong being lashed with a ravenous Typhoon yet again recently left quite a few question marks.  It’s a marvel how these people manage to stay at the top in spite of being at the receiving end of nature’s fury so frequently. They have effectively established a very strong technological solution that helps them work through such disasters with preparedness. They are smartly using LED video walls for monitoring and forecasting at each step, so that the city remains largely unaffected by calamities.

Here is how LED video walls can help in weather forecasting, climate monitoring, disaster predictions, etc. to help in disaster preparedness:

-Detailed data compilation at one place

 Advanced imaging and multiple data collection systems are needed in weather and civil aviation department where these mammoth video walls compile and display different types of information. The data so collected is detrimental in issuing weather warnings for the days ahead, so that the contingency arrangements can be made accordingly.

-Multiple data display

The video wall technology can take one input and decipher it in multiple ways for processing and analysing data from all conceivable angles. For instance, to track natural calamities such as typhoons, there will be a ton of factors that need to be considered and studied. From rainfall to wind velocity, direction, visibility and precipitation in various areas, there are eons of data that need to be displayed and analysed at one go by multiple people. Video walls offer that kind of bandwidth to display all the requisite data on one huge screen.

- Multiple data input sources

The video wall may take data from one input source and display it in different ways or it may take data from several sources and display it on the screen.

- HD images

The display offered by LED videowalls such as those manufactured by Delta is HD, so that clear images can establish the most accurate course of action to be taken. 

- 24X7 functioning

The LED video walls are designed keeping in mind the fact that they will be running 24x7 and so are built to serve for a long period of time. Hence their design, display and components are integrated in a way to perform seamlessly, with no scope of any break down. 

LED videowalls like the ones offered by Delta provide the perfect solution for multi screen operations of the data received from multiple sources where it’s imperative to stream live data at all times. These thin displays complement the high tech designs of data observatories. Besides, they are energy saving and cost effective too. They have multiple products and models of video walls, so that whatever be the purpose, Delta will have a solution!

Why People are Opting for DLP Video Walls

You must have seen those cool and huge display systems in movies or television series. People are shown keeping a watch over it and taking notes or details from it in the control rooms. Those huge displays are technically known as video walls.

Video walls were invented because there was no single display source that was so huge and had a display with high resolution and contrast as well as uniform brightness. A video wall is actually a group of several rear-projection display cubes that are arranged next to one another in order to display different parts of a single image as one. The image or data displayed through the video wall looks very big and seems to come from a single display source. Moreover, it enables several people to keep a track of the information simultaneously and collaboratively.

There are different types of technology involved in the manufacturing and designing of video walls, such as LCD technology and DLP technology. The DLP video walls and LCD video walls are used in the following sectors and industries:

• Broadcast department
• Defense
• Energy
• Investigative agencies
• Intelligent traffic systems
• Power and utilities
• Public and emergency services
• Space stations
• Stock exchanges
• Government bodies
• Disaster management centers
• Surveillance and security
• Telecommunications

The DLP video wall displays amazing image quality with accurate color depth, brightness and contrast. It helps a person to read and observe data with utmost ease, without causing any strain to the eyes. The video walls are designed in accordance with the latest technology and are installed with a DMD chip. This chip has up to 2 million hinge-mounted microscopic mirrors that can switch on and off up to a several thousand times in one second. It helps the video walls to reflect around 1,024 shades of gray and also create around 35 trillion colors. Moreover, a DLP subsystem has a color filters, digital processing and formatting, light source, optics, a DMD and a projection lens.

The DLP video walls produce 3D-like images that are really sharp and clear. Apart from its excellent display, this type of video walls are widely admired and used for their durability and reliability. Video walls enabled with DLP technology has a lifetime estimate of more than 1,00,000 operating hours and more than 1 trillion mirror cycles. The amazing features and advantages of these video walls have increased their demand in the market.
