UK image processing software specialist Spectral Edge is launching its RGB (visible light) and Near Infrared (NIR) Fusion solution ‘Spectral Edge Fusion’ into the surveillance market at ISC West 2019 to be held in Sands Expo, Las Vegas from 10-12th April.

Spectral Edge Fusion can provide surveillance cameras with high quality, colour accurate images even in low or mixed lighting conditions. It is also able to capture much more depth and colour in detail that would normally be hidden in foggy or hazy conditions.

Spectral Edge Fusion is particularly useful in supporting video analytics capabilities such as facial, object and action recognitionCrucially, as well as delivering better-looking images to human viewers, the Spectral Edge Fusion platform enables applications such as facial or object recognition to deliver higher success rates in low light conditions.

Supports facial and object recognition

Spectral Edge Fusion is particularly useful in supporting video analytics capabilities such as facial, object and action recognition, as well as other surveillance applications which demand high quality images to achieve accurate identification to minimise false positive alerts.

Spectral Edge Fusion uses its patented fusion algorithm to create three channels from four original channels: Red, Green, Blue and NIR light. It’s the only technology on the market today which can perform this light fusion without introducing pixilation, artefacts or additional noise. Spectral Edge predicts its development in RGB and NIR fusion will render RGB-only sensors obsolete within the next few years once the technology is proven in the field.

Improved contrast and signal-to-noise ratio

Spectral Edge Fusion ensures minimal loss of resolution - while delivering improved contrast, dynamic range and signal-to-noise ratioSpectral Edge Fusion also ensures minimal loss of resolution - while delivering improved contrast, dynamic range and signal-to-noise ratio. So, what’s lost in colour as daylight fades is made up for in additional texture and depth of image which the NIR delivers given suitable IR illumination.

It also generates a build and Bill of Materials saving for surveillance camera manufacturers because only one readily-available sensor and lens is needed for a single day/night camera. No mechanical switching between sensors is required and there is no requirement for an IR-cut filter. This helps to minimise moving parts which wear out over time and extends surveillance cameras’ Mean Time to Failure.

No additional costs in using NIR

An additional cost advantage flows from using NIR because it can be detected by the same sensor chip as RGB. There is no extra cost associated with such manufacturing variants. Put simply, some of the pixels which sense visible light are replaced with pixels sensitive to NIR. Spectral Edge Fusion has already been successfully tested on a range of such sensors which support both RGB and NIR wavelengths.

Spectral Edge Fusion has already been successfully tested on a range of such sensors which support both RGB and NIR wavelengthsSpectral Edge Fusion can be fitted into System-on-Chips (SoCs), which process sensor outputs without increasing the silicon area significantly. The innovator plans to have a prototype development (with RGB+NIR fusion capability built into it) available to show chip and camera manufacturers at its stand (number 41030) at the show.

Optimising video analytics innovations

Rhodri Thomas, Chief Executive Officer, Spectral Edge, said: “We think that our innovation in RGB+NIR fusion could render RGB-only sensors obsolete a few years from now. We are looking forward to talking about this with surveillance market players in the US where so many great camera and chip manufactures operate.

The market here is highly-focused on manufacturing high quality sensors designed to optimise the latest video analytics innovations. It is these vendors, system builders and integrators, which Spectral Edge plans to meet at ISC West this year.

Helping colour blind viewers

A modified version of this technology was licensed by Sky Italia to improve perceptual detail for HDTV viewingSpectral Edge was spun out of University of East Anglia’s Colour Lab five years ago and initially applied its technology to the world of broadcast television to support colour blind viewers to help them view the difference between colours on-screen.

A modified version of this technology was licensed by Sky Italia to improve perceptual detail for HDTV viewing. As a result of this licensing arrangement with Sky Italia, some 55 satellite channels in Italy use Spectral Edge technology today. Spectral Edge recently secured a third round of £4m funding to accelerate its R&D work as the company tightened its focus on the surveillance camera market.

Managing security during unprecedented times of home working
Managing security during unprecedented times of home working

Companies are following government guidance and getting as many people as possible working from home. Some companies will have resisted home working in the past, but I’m certain that the sceptics will find that people can be productive with the right tools no matter where they are. A temporary solution will become permanent. But getting it right means managing risk. Access is king In a typical office with an on-premise data centre, the IT department has complete control over network access, internal networks, data, and applications. The remote worker, on the other hand, is mobile. He or she can work from anywhere using a VPN. Until just recently this will have been from somewhere like a local coffee shop, possibly using a wireless network to access the company network and essential applications. CV-19 means that huge numbers of people are getting access to the same desktop and files, and collaborative communication toolsBut as we know, CV-19 means that huge numbers of people are getting access to the same desktop and files, applications and collaborative communication tools that they do on a regular basis from the office or on the train. Indeed, the new generation of video conferencing technologies come very close to providing an “almost there” feeling. Hackers lie in wait Hackers are waiting for a wrong move amongst the panic, and they will look for ways to compromise critical servers. Less than a month ago, we emerged from a period of chaos. For months hackers had been exploiting a vulnerability in VPN products from Pulse Secure, Fortinet, Palo Alto Networks, and Citrix. Patches were provided by vendors, and either companies applied the patch or withdrew remote access. As a result, the problem of attacks died back.  But as companies race to get people working from home, they must ensure special care is taken to ensure the patches are done before switching VPNs on. That’s because remote desktop protocol (RDP) has been for the most part of 2019, and continues to be, the most important attack vector for ransomware. Managing a ransomware attack on top of everything else would certainly give you sleepless nights. As companies race to get people working from home, they must ensure special care is taken to ensure the patches are done before switching VPNs on Hackers are waiting for a wrong move amongst the panic, and they will look for ways to compromise critical serversExposing new services makes them also susceptible to denial of service attacks. Such attacks create large volumes of fake traffic to saturate the available capacity of the internet connection. They can also be used to attack the intricacies of the VPN protocol. A flow as little as 1Mbps can perturbate the VPN service and knock it offline. CIOs, therefore, need to acknowledge that introducing or extending home working broadens the attack surface. So now more than ever it’s vital to adapt risk models. You can’t roll out new services with an emphasis on access and usability and not consider security. You simply won’t survive otherwise. Social engineering Aside from securing VPNs, what else should CIO and CTOs be doing to ensure security? The first thing to do is to look at employee behaviour, starting with passwords. It’s highly recommended that strong password hygiene or some form of multi-factor authentication (MFA) is imposed. Best practice would be to get all employees to reset their passwords as they connect remotely and force them to choose a new password that complies with strong password complexity guidelines.  As we know, people have a habit of reusing their passwords for one or more online services – services that might have fallen victim to a breach. Hackers will happily It’s highly recommended that strong password hygiene or some form of multi-factor authentication (MFA) is imposedleverage these breaches because it is such easy and rich pickings. Secondly, the inherent fear of the virus makes for perfect conditions for hackers. Sadly, a lot of phishing campaigns are already luring people in with the promise of important or breaking information on COVID-19. In the UK alone, coronavirus scams cost victims over £800,000 in February 2020. A staggering number that can only go up. That’s why CIOs need to remind everyone in the company of the risks of clickbait and comment spamming - the most popular and obvious bot techniques for infiltrating a network. Notorious hacking attempts And as any security specialist will tell you, some people have no ethics and will exploit the horrendous repercussions of CV-19. In January we saw just how unscrupulous hackers are when they started leveraging public fear of the virus to spread the notorious Emotet malware. Emotet, first detected in 2014, is a banking trojan that primarily spreads through ‘malspam’ and attempts to sneak into computers to steal sensitive and private information. In addition, in early February the Maze ransomware crippled more than 230 workstations of the New Jersey Medical Diagnostics Lab and when they refused to pay, the vicious attackers leaked 9.5GB or research data in an attempt to force negotiations. And in March, an elite hacking group tried to breach the World Health Organization (WHO). It was just one of the many attempts on WHO and healthcare organisations in general since the pandemic broke. We’ll see lots more opportunist attacks like this in the coming months.   More speed less haste In March, an elite hacking group tried to breach the World Health Organization (WHO). It was just one of the many attempts on WHOFinally, we also have bots to contend with. We’ve yet to see reports of fake news content generated by machines, but we know there’s a high probability it will happen. Spambots are already creating pharmaceutical spam campaigns thriving on the buying behaviour of people in times of fear from infection. Using comment spamming – where comments are tactically placed in the comments following an update or news story - the bots take advantage of the popularity of the Google search term ‘Coronavirus’ to increase the visibility and ranking of sites and products in search results. There is clearly much for CIOs to think about, but it is possible to secure a network by applying some well thought through tactics. I believe it comes down to having a ‘more speed, less haste’ approach to rolling out, scaling up and integrating technologies for home working, but above all, it should be mixed with an employee education programme. As in reality, great technology and a coherent security strategy will never work if it is undermined by the poor practices of employees.

How does audio enhance security system performance?
How does audio enhance security system performance?

Video is widely embraced as an essential element of physical security systems. However, surveillance footage is often recorded without sound, even though many cameras are capable of capturing audio as well as video. Beyond the capabilities of cameras, there is a range of other audio products on the market that can improve system performance and/or expand capabilities (e.g., gunshot detection.) We asked this week’s Expert Panel Roundtable: How does audio enhance the performance of security and/or video systems? 

How have standards changed the security market?
How have standards changed the security market?

A standard is a document that establishes uniform engineering or technical criteria, methods, processes, and/or practices. Standards surround every aspect of our business. For example, the physical security marketplace is impacted by industry standards, national and international standards, quality standards, building codes and even environmental standards, to name just a few.
