Displaying Hundreds of IP Cameras on a Video Wall

IP cameras have made enormous gains in image quality, resolution and frame rate in a very short time. Today it is not uncommon to see video resolutions of 20 megapixels or greater at frame rates of 15 to 30 fps. IP surveillance architectures rely on distributed processing to encode and compress video from raw formats captured by the camera imager into streams which pass across common Ethernet networks. Every camera is an encoder, and as you add more cameras, you naturally need more encoding capacity. The question is, how do you scale up decoding capacity to view the rapidly growing population of cameras?

Video Management Servers (VMS) are generally designed to receive the encoded video from cameras and write the video data as a file directly to disk, without the need to decode the video. This is ideal for storage, as the files remain compressed and the CPU/ GPU of the receiving VMS are not taxed with much processing.

VMS design has traditionally been premised on forensic, post event, evidence storage and review in order to prosecute criminals or avoid trip and fall liability law suits. Generally VMS systems assume a very limited number of live cameras being simultaneously viewed. For this reason, scalable IP decoding has not been a focus for VMS manufacturers.

However, as IP cameras proliferate, their utility for purposes such as safety monitoring, industrial operations monitoring, traffic monitoring, and general situational awareness increases. Security Operation Centers, Traffic Management Centers, and Operation Management Centers increasingly demand more cameras to be displayed. But traditional VMS architectures are not up to the task.

A modern x86 architecture PC with a contemporary GPU is capable of decoding about 150 frames per second of 1080p (2 megapixel) H.264 compressed video. This represents only 5 video streams at 30fps, and only 1 stream at 4K (8 megapixels). A common trick of the trade is to encode two streams at each camera, one for recording at full frame rate and resolution, and one at lower resolution and frame rate for live viewing. But doesn’t this defeat the purpose of using a megapixel camera? Why compromise the quality of the video that they operator can see?

An Ultra High Definition video wall processor is the solution. For instance the RGB Spectrum MediaWall V can connect to up to 36 PC workstations, each capable of decoding 5 1080p streams. That’s 180 1080p30 streams or 720 D1 streams. Each pc input can be routed into a scalable window which can be displayed on a video wall. And the video wall can span up to 24 1080p monitors. That’s 49.7 million pixels on the wall! The video wall processor allows you to leverage the IP decoding capacity of many disparate computers, yet combines the results into a single large display canvas.

In addition, RGB Spectrum offers the ability to control all source computers, including decoding engines, with using its innovative Multipoint Control Room Management System (MCMS), allowing an operator to change the settings on any computer feeding the wall processor.

Using a video wall processor in combination with multiple computers serving as IP decoders is an effective way to scale up the number of cameras that can be simultaneously viewed.

Microsoft Details HoloLens (Limited) Battery

  • PDF

HoloLens

Microsoft evangelist Bruce Harris gives a few details on the HoloLens augmented reality headset at a Tel Aviv event-- including the fact the device battery lasts for 5.5 hours of regular use. As reported by Petri, "heavy loads" slash battery life to just 2.5 hours.

The power issue also limits the display capabilities of the headset, leading to a field of view "similar" to a 15-inch monitor close to the viewer's face.

Such fact might make the Hololens look limited, but Microsoft does have a few tricks up its sleeve-- the device runs any universal Windows 10 application and is "totally wireless," with no wired option available.

Connectivity comes through wifi and Bluetooth, and the users can pair Hololens headsets together to share AR experiences.

Microsoft is still to provide a Hololens consumer release date, but shipments to developers should start from Q1 2016.

Next Step in Flat Screens? It’s Optical Laser Panels

  • PDF

dnp LaserPanels

At ISE 2016, dnp denmark will present what it calls “the next step in the evolution of flat screens:” optical laser panels.

The new generation of dnp LaserPanels offers 100” high-contrast images at around 50% of the cost per screen area square inch of LED-backlit LCD screens.

And as the dnp LaserPanel uses a laser projector, low running costs and no lamp changes should drive down the total cost of ownership.

The highly attractive size-cost-quality ratio of the display provides a compelling combination, believes Soeren Kraemmergaard, VP of Global Sales and Marketing, dnp. “If the market is clear about one thing, it’s that big is truly beautiful when it comes to display technology,” he says. “The problem is that when you take ordinary flat screens over 80” in size, there is a disproportionate price increase.”

dnp LaserPanels overcome this restriction by combining optical screen technology with Ultra Short Throw Laser projection. The result is a display that can be mounted on the wall, with the projector above or below the screen shooting from a steep angle. This makes installation easy, and users never need to worry about stepping into the beam while presenting.

The new display package is the first all-in-one bundled solution from dnp. And dnp hope to meet new potential sales partners at ISE.

“We see a huge potential for 100” dnp LaserPanels particularly in the presentation and education markets, and we are looking for channel partners who can move bundled solutions in these segments,” says Kraemmergaard

The dnp LaserPanel is also available in a Touch version, which has a rigid screen, interactive camera and IR pens for interactive presentations. Both variants come with everything required for set up, including screen, projector and wall mounts.

dnp will also perform a shoot-out between a dnp Supernova Blade Screen, with both 08-85 and 23-23 screen material and a standard white screen, to demonstrate how optical screen technology can dramatically enhance the quality of projected images in a high ambient light environment.

Visitors will also be able to experience a new and improved version of the retractable dnp Supernova Flex Classic Screen.

Model 550 MediaWall V

RGB Spectrum calls its MediaWall V Display Processor “the world’s first true 4K video wall processor, offering up to 4K resolution I/O, single wire connectivity and fully scalable windows.”

A new MediaWall V display processor now includes a second, larger chassis and expanded features bringing more flexibility and capability to the product line.

This new Model 550 MediaWall V wall processor offers more inputs and outputs in HD and 4K Ultra UHD) formats (but, no specification for color bit depth). Input capacity has been doubled to 36 direct sources plus IP inputs. Increased output capacity supports wall arrays of up to 24 HD/2K displays or up to 12 4K/UHD displays.

Functionality is further expanded with new switched output modules. These can take the place of an external matrix switcher, providing up to 18 additional outputs, a convenient, cost-effective way to route sources to other displays, operator control stations, conference rooms, or other downstream devices such as digital video recorders. Any input can be routed to any number of outputs, providing significant switching flexibility built right into the display processor.

These expanded input and output capabilities enhance RGB Spectrum’s MultiPoint Control Room Management System (MCMS) which adds arbitrated KVM control over system resources for the ultimate in control room management.

An optional Application Processor decodes incoming IP streams. IP camera and other H.264 streams at resolutions up to 4K/UHD (3840×2160/30) are decoded on a separate processor embedded in the MediaWall V chassis. This unique dual-processor architecture guarantees adequate CPU resources to video wall operations while the second processor handles IP decoding.
