can be accessed from anywhere. Together, they provide an intelli- gent, easy-to-use platform to en- rol, configure and maintain every Nureva audio system. IT admins are tasked with managing users and devices across an increasing- ly distributed workforce, a shift that recent research from Global Workplace Analytics suggests may become permanent. Nureva Console supports this shift by making it simple for IT staff to manage and monitor all Nureva audio systems remotely. Through Nureva Console’s dash- board, IT staff can enrol their Nureva audio systems and then manage them from anywhere. In a live list view, they can see all devices, what rooms they’re in, whether the system is online, what version of firmware is run- ning and if an update is available. The ability to drill further into the system information of a de- vice lets IT push out an update

and manage device settings, such as the microphone, speak- er, base and treble levels, and even change what is shown on the HDL200 system’s


display.


This keeps customers in control of all their Nureva audio systems, whether there is 1 or 10,000 to configure, monitor and manage remotely. With regular firmware updates, Nureva audio systems are always advancing to meet the evolving needs of business and learning environments. Once a Nureva audio system is enrolled through Nureva Console, customers also receive an additional year of war- ranty, from two years to three. Nureva


Console provides the


infrastructure for future integra- tions between Nureva audio sys- tems and third-party solutions. For example, in the near term, IT managers can use Nureva Con- sole to integrate their room book- ing and room control systems with Nureva’s HDL200 system to display room availability and exer- cise further in-room control. “With the growing trend toward distributed teams, Nureva Con- sole makes it easy for IT staff to get a global view of all their Nureva audio systems from any- where,” said Nancy Knowlton, Nureva’s CEO. “We are excited to offer customers a complimentary service that delivers full remote management capabilities and flexibility for broad deployment of Nureva’s audio systems.”


classrooms of all shapes and sizes too, as both models offer a 110'' diagonal projection image from as little as 51 cm away from the screen surface. Meanwhile, the projectors’ 3,500 lumens of brightness, 1080p resolution, and 10,000:1 contrast ratio en- sure clear, crisp and bright pro- jection, aiding viewing comfort further while guaranteeing a per- fect image. Teachers and lecturers will ben- efit from increased eye comfort; when they’re standing in front of the projected image, there’s no eye glare for them to endure, nor any shadow obstruction. Further- more, students will benefit from greater comfort, as the projected image is based on light reflect- ed from the projection surface, which is easier for the eye to view, particularly over a long period of time.

BenQ claims to have intro- duced the world’s first wireless Android-based smart projector range for business; meeting the needs for faster and eas- ier connectivity in meetings. Launching three projectors, the EH600, EW600 and EW800ST; the range offers varying reso- lutions and brightnesses up to 3500 lumens, connectivity ca- pabilities and innovative Smart features via its on-board android system. With an increase of BYOD in the professional environment and a mixture of team members working from home or across different


office locations, the


new projector range simplifies connectivity both remotely and in-person. While collectively en- couraging workers on different operating systems, including Mac/iOS, Android, and PC, to collaborate.


Offering a myriad of ways to connect and share ideas, screen mirroring allows up to four users to connect from PCs, tablets or smartphones, to simultaneous- ly share and edit content wire- lessly to the display. BenQ’s dedicated smartphone app, In- staShow, as well as Bluetooth technology also allows users to control the projector’s own in-


terface from their devices, for easy, live presentation control without having to physically touch the projector’s hardware. The EH600, EW600 and EW800ST all come with a suite of apps to get the meeting start- ed right away such as a Firefox browser, TeamViewer and Blizz for fast and intuitive collabo- ration. BenQ’s InstaShare app also let’s remote staff connect to the screen for collaboration sessions in real-time, letting them contribute notes and save and record presentations. The on-board android system supports a wide range of file types including JPEG, PDF, Microsoft Word, Excel, Power- Point, enabling users to pres- ent material without having to convert files into a uniform format.


Users can also load files onto a USB drive and plug directly into the projec- tor, interfacing with the files wirelessly from the smartphone app rather than via a laptop or other source. Alternatively, in- built Bluetooth technology al-

sounds and messages are com- municated crisply and clearly. Eco-friendly and energy saving features include a sleep timer and auto-power-off functionality when there is no signal input to help to conserve energy, while contributing to lower running costs. DH772UST & DH773USTi users can be assured of the pro- jectors’ durability too, with up to 12,000 hours of lamp-life, while a five-year education warranty brings further peace of mind both now and in the future. Network managers will be impressed with their integrated network monitor- ing and management solutions including Crestron RoomView. Naturally, the UST projectors are compatible with NovoConnect, the wireless collaboration solu- tion, enabling students to partici- pate from their own digital device directly on the screen to share up to four devices simultaneously.

Plastic or metal? When peace of mind must be top priority!


At the design stage of any product, there’s a lot to think about in terms of the materials you might use. Different materials offer different properties and it’s important to weigh up the key attributes and match them to the needs of the application.


Regardless of the end product in question - a toy, a cake, an electronic device - character- istics such as aesthetics, lon- gevity, weight, colour, strength, cost… these and so many more will need to be carefully considered to ensure the best outcome and a product that’s fit-for-purpose. One vitally im- portant characteristic of any item, whatever its intended purpose, is one that upholds the safety of the consumer.


Safety first


There’s no question about it, when it comes to public safely, there can be no compromise. Whilst enforced by law through health and safety


legislation,


there is also a moral obligation to take care of people’s well-be- ing and to value their safety as a primary concern. Let’s consider the properties of two primary materials used in display electronics and ask, for specific elements of con- struction,


would


plastic or metal? Fire-retardancy


Protection from fire in public spaces has significant


impli-


cations for the selection of materials. The construction of buildings must by law inte- grate fire-retardant elements designed to limit the spread of fire and give more time for peo- ple to escape.


In 2019, Brussels Airport launched a tender that de- scribed LCD and LED based video wall products as ‘clad- ding’. For manufacturers of electronic equipment this has significant consequences as their products now require the same fire classification as construction materials. The fire load test measures a prod- uct’s reaction to fire including its contribution to the spread and intensity of flame and the release of smoke and burning droplets.


In order to pass this test, the use of materials within elec- tronic equipment will be of paramount concern and an un- derstanding of the property of certain materials will be funda- mental to its design.


• As a non-combustible mate- rial, metal is highly heat resis- tant with a very high melting point, slowing its degradation under extreme high tempera- tures.


• Plastics, in contrast, are high- ly combustible. Burning plastic


you choose


releases dangerous chemicals and drips as it burns.


Naturally enough, being easy to fabricate, plastic in one form or another will be needed for cer- tain components, but when it comes to the chassis or frame- work upon which the device is built, likely to be a large ex- panse and the greatest propor- tion, the choice of material will be fundamental. What would you choose, plastic or metal? An LED product built using a plastic chassis is highly un- likely to pass the fire load test due to its combustibility. There are ways around it, by invest- ing in an array of structural or plant-related compensation such as sprinklers and smoke evacuation systems. It is an additional costly investment, but more to the point, when it comes to peace of mind, would you choose plastic or metal?


Heat resistance


Whilst it is hoped that a prod- uct’s fire-retardant properties will never have to be put to the test in real-life, heat remains a challenge for electronic equip- ment every day that its opera- tional.


Heat is no friend to electronic devices. Managing heat build- up and maintaining a constant temperature is a concern for manufacturers and operators. Not only does it impact on the lifetime of the device and the consistency of its performance, it is vital in guarding against combustion.


• Metal is an excellent con- ductor of heat. As such, it is highly efficient at dissipating heat, expelling it away from the internal workings of the device. • Plastics are thermal in- sulators, high temperatures are trapped inside the device, building up over time.


If you want to protect your investment and extend the life of your device, which material would you like to see specified for the chassis, plastic or met- al?


Precision


Exactness of alignment is fun- damental


to creating overall


visual impact, after all, who wants to see gaps between the modules on an LED wall? Heat is a major contributing factor as it directly impacts the integrity of the cabinets which support the LED pixel cards. • Metal is precisely machined to size. It is strong, rigid and


durable even in changing tem- peratures.


• Plastic is pliant. It will ex- pand and contract when sub- ject to changing temperatures. When you have invested in the latest technology you want it to look sleek and seamless, in perfect alignment and unifor- mity, creating the impression of a single vast canvas. You want your audience to say WOW! Which material says wow to you, plastic or metal?


Recyclability


The recyclability of a product will have implications not only for the environment but also for the reputation of your business. Organisations must act respon- sibly towards the environment to meet the expectations of business stakeholders and so- ciety in general.


• Metal is 100% recyclable. It can be recycled again and again without altering its prop- erties.


• Not all plastics are recycla- ble. Because of the way plastic is fabricated, it is not always possible to be returned to its original constituent elements. When you’re quantifying your carbon footprint, which materi- al usage are you most confident to declare, plastic or metal?


So, what’s it to be, plastic or metal?


The question is not a simple case of cost over quality, it is a matter of fit-for-purpose design at a reasonable cost. That question alone makes the choice between plastic or metal a far more straightforward out- come.


Surely the question it-


self is far simpler. Why plastic? • Editor’s note: The European Standard EN 13501-1 provides the reaction to fire classifica- tion procedure for all products and building elements. Ac- cording to this Standard, re- action to fire is the response of a product in contributing by its own decomposition to a fire to which it is exposed, under specified conditions (not to be confused with the fire resis- tance). An EN-13501-1 test is identifying products that are flame retardant, non-combusti- ble, not dripping and no or very low smoke development. These results cannot be achieved with product made mainly from plastic which is combustible, drips and creates smoke.
