When the first event music, “Video Killed the Radio Star” premiered in 1981, it started a video revolution. A lot has changed since then, but video’s relevance in our culture has increased.
With our obsession over video and corresponding camera capabilities such as HD and 4K, it’s easy to miss an equally crucial component that can make or break the effectiveness of an entire surveillance system: storage. Unfortunately, many surveillance professionals are using the wrong drive. Rather than being designed for continuous capture of HD or FHD video from multiple cameras, a drive that is not optimised for surveillance systems can drop frames or even consume more power, generating more heat and create major reliability issues. This could drastically reduce the life of a drive, adversely affecting the read and write operations in a surveillance system. These solutions may cost the customer less upfront, but could eventually affect a business when performance, reliability and reputation are compromised.
The right surveillance storage solution should offer high performance, efficiency and capacity that has been tested in harsh surveillance environments. How can you tell the difference?
The Good, The Bad and The Ugly: What to Look for in Surveillance Storage
There are several specific things to look for when evaluating whether a drive has been designed with surveillance in mind:
• Always on: A surveillance system works 24×7. If the storage drive hasn’t been designed for constant, never-ending read/write operations, it won’t be able to keep up.
• Performance Reliability: Some drives, like WD’s Purple surveillance-class hard drive family, include special technology (called AllFrame in this case) that improves playback performance and works with ATA streaming to reduce errors and frame loss.
• RAID-enabled: To increase peace-of-mind for your customer, you may also want to look for a drive with RAID or Redundant Array of Inexpensive Disk capabilities. A drive with this capability can use two or more hard disks to create a safety net for failed hardware by ensuring that the image is still being captured even if one drive isn’t working. This lessens interruptions in productivity and decreases the chances of data loss.
• Low power consumption: While “low power consumption” might not be first on your list of things to look for in a hard drive, the need for always-on capability makes this crucial. Having a drive that calculates the optimum seek speeds won’t generate as much heat, even in passively-cooled storage enclosures, making it more reliable and friendlier to your customer’s wallet.
• High camera count support: A high number of cameras, an NVR system or a longer retention period will require higher storage use and an even greater need to ensure you have chosen a drive that will meet the customer’s needs. Look for one with up to 6 TB of capacity on a single drive.
• High system bay count support: The right drive will include hardware vibration sensors to enable higher drive-count systems as well as higher system and hard drive workloads.
• Extensive compatibility with cameras: Needless to say, the drive you select needs to work with the cameras you are planning to install. One that works with most of the different cameras you could install will make it even easier to keep the right drive on-hand, regardless of your current installation scenario.
• Rugged exterior: In some cases the drive may need to live and perform continuously in harsh environments. In this case, you’ll want one with tarnish-resistant PCBA protection.
• Easily upgradable: In an ideal world, your customer occasionally asks to upgrade or expand their existing surveillance system. A drive that scales with a system when the need arises makes your job easier.
Considering the importance of storage in surveillance systems, it is also helpful to use a capacity calculator to help determine how much storage is needed for the length of time data is to be maintained for a particular surveillance system. Vendors like WD (www.wd.com) offer calculators and drive selection tools to help find the right drive and capacity that best suits your needs.
Rather than selecting the inappropriate drive for your surveillance solution, spend additional time conducting research into which drive is engineered for a surveillance environment and is able to meet the specific demands of the application. It can save hassle, money and even guarantee conviction of a perpetrator of a crime in the long wrong.
Nokia 7.2: The sweet-spot for mid-range smartphones
Nokia has hit one of the best quality-to-price ratios with the Nokia 7.2. BRYAN TURNER tested the device.
Cameras are often the main factor in selecting a smartphone today. Nokia is no stranger to the high-end camera smartphone market, and its legacy shows with the latest Nokia 7.2.
In many aspects, the device looks and feels like an expensive flagship, yet it carries a mid-range R6000 price tag. From its vivid PureDisplay technology to an ultra-wide camera lens, it’s quite something to experience this device – especially knowing the price.
Before powering it on, one notices the sleek design. The front features a large, 6.3” screen, with a 19.5:9 aspect ratio. Like many phones nowadays, it features a notch, but it is smaller than the usual earpiece-and-camera notch. Instead, it features a small notch for the front camera only. It hides the front earpiece away in a slim cutout, just under the outer frame. While it’s not the highest screen-to-body (STB) ratio, it has a pretty slim bezel with an 83.34% STB ratio. It loses some of this to an elegant chin on the bottom that shows the Nokia logo. This is all protected by a Gorilla glass certification, which makes it a little more difficult to shatter on an impact.
It’s encased by a Polycarbonate composite outer frame, which seems metal-like but will withstand more knocks than an aluminium frame. On the right side, it features a volume rocker and a power button and, on the left side, a Google Assistant button, which starts listening for commands when pressed. Above the button is the SIM and SD card tray. On the top, it houses a very welcome 3.5mm headphone jack. On the bottom, it has a speaker grille and a USB Type-C port. Overall, the positioning of the buttons takes some getting used to because the Assistant button and power button are similarly sized, and many smartphones place the lock button on the opposite side of the volume rocker.
The back features a frosted Gorilla glass panel, like the front. The frosted design is quite understated and yet another elegant design feature of the device. A fingerprint sensor sits in the middle and, towards the top, the device has a circular camera bump, not too different from the Huawei Mate 30 series. The bump features two lenses, a depth sensor, and a flash. The camera system has been made in partnership with Zeiss optics to produce high-quality photography.
When powering on the device, one is greeted with the Android One logo, which is Nokia’s promise that its users will always be among the first to get the latest Android security and feature updates. This is one of the defining purchase points for users looking to get this device, as it features the purest, unedited version of Android available.
This, in turn, allows the device to run the latest software by Google that enables the device to get better over time. This is done by using Google’s Artificial Intelligence engine, which learns how one uses the device and optimises apps and services accordingly. That translates to the phone’s battery life actually extending over time, instead of deteriorating like other smartphones that are weighed down by battery hungry apps. The concept was pioneered by Huawei in the Mate 9.
The rear camera is excellent for snapping pictures and features a 48MP Sony sensor for accurate colour reproduction. This puts the device in the league of the Google Pixel and Apple iPhone devices, which also use Sony sensors. By default, the device is set to take pictures at 12MP, which is what makes the photos look great, as it blends 4 pixels into one for a high level of sharpness and colour accuracy, but users can bump up the resolution to the full 48MP if they want to zoom in a bit more.
The 8MP wide-angle lens spans 118-degrees, and proves extremely useful for getting everyone in the shot. It also features some great colour accuracy. The 5MP depth-sensing lens is purely for the portrait mode, which adds a blur effect to the background of the photo. It features a 20MP selfie camera, which also provides excellent sharpness and a portrait mode.
The most impressive part of this system is the Pro camera setting, which can help take photos from excellent to extraordinary. We managed to get some excellent low light photography by adjusting the shutter speed, ISO, and exposure. The setting is pretty easy to use and it’s worth it for users to learn how it works.
The PureDisplay also helps make photos and video look great. The 7.2’s PureDisplay has a 2160 x 1080 resolution, at 401 pixels per inch (ppi). It also makes use of HDR10 and covers 96% of the DCI-P3 colour gamut, which makes the colours very vibrant. Some of these display features are not even found in some high-end phones on the market, so it’s very surprising that this tech is in a mid-range device.
At this price, there is one drawback: the processor. It houses a Qualcomm Snapdragon 660, which is neither bad nor good. It performs well in many situations, but begins to stutter on heavier graphical applications like Fortnite and PUBG Mobile. That said, all other applications of the device work perfectly, and multi-tasking is very fluid between regular apps.
At a recommended selling price of R6,000, the Nokia 7.2 is one of the most feature rich and aesthetically pleasing devices available in this price range.
Voice interface moves digital wars to ‘first mile’
By RICHARD MULLINS, Managing Director for EMEA at Acceleration
Anyone who often travels on the London tube will notice people around them – usually students and young professionals – speaking into their smartphones even in sections of the underground without Wi-Fi or cellular coverage. They’re not sweet-talking their mobile devices, but cueing up a series of WhatsApp voice messages to be sent to their friends and colleagues as soon as they walk back into an area with an Internet connection.
This shift away from text-based and visual communication to multi-sensory (voice and visual) is one of the most significant trends to emerge from the next wave of artificial intelligence technologies. Many members of Generations X and Y abandoned voice calls for instant messaging once they got smartphones; now, the next generation are becoming more vocal in how they interact with – and through – machines.
We’re already seeing rising adoption of conversational voice interfaces, as young and imperfect as the technology still is. Research from comScore predicts that half of all searches will be performed via voice by 2020, while a study by Voicebot.ai indicates that nearly one in five US adults own a smart speaker or have access to one in their homes.
This trend is one reason that we are seeing the battle for the digital customer move away from the ‘last mile’ to the ‘first mile’ at a rapid speed. Now that the giants of ecommerce have largely solved the ‘last mile’ challenge of reliable logistics and rapid delivery, they are looking at ways they can tighten their grip on the first digital mile, where customers engage with and discover content, product and services.
Raising the stakes
This race to own the customer interface is not new, but the stakes are rising. We already live in a world with two major smartphone platforms (Apple’s iOS and Google’s Android), and now a handful of companies (Google, Facebook, Microsoft, Apple and Amazon) are seeking to own the voice interface with smart devices like speakers, kitchen appliances and home security systems.
Most consumers are today using voice conversation interfaces for simple content requests – Alexa, give me the news headlines; Siri, play my party mix – and the experience can be somewhat clunky. However, technology is improving exponentially, as we saw earlier this year when Google demoed its assistant phoning a hairdresser to make an appointment on behalf of a user.
Such interfaces are likely to become the place where a high proportion of customers are converted and complete transactions in the next few years. In other words, the likes of Apple and Google will have even more power over what consumers see, hear and interact with than they do today. Brands should be thinking about how they will prepare themselves for this future.
One of the first considerations is how they can use voice to engage with customers in an increasingly natural and simple nature. Today, it is usually easy to tell when you are speaking to a virtual assistant or chatbot, but in future, these interfaces will become harder to tell humans and machines apart, unless you are told.
This is an opportunity to offer personalised service in an automated manner—the human touch at machine scale. Brands that offer the best experiences through their conversational interfaces will have a competitive advantage. This will not just be about the AI driving the interaction, but also about how brands use data to personalise interactions and make them more relevant to customers.
How will you reach your customers?
Brands also need to decide how they will reach their customers in the first place – will they create services for platforms like Alexa and focus on mobile apps? Or will they try to take control of more of the digital first mile themselves? This will be a daunting challenge, but the rewards may be significant since the companies in the digital first mile will control the data and own the customer.
For this reason, we can expect to see those companies with the resources to do so focus on owning more of the customer interface and becoming the gateways to service and commerce for their client base. They will partner with other big brands to create platforms, experiences and digital destinations where customers can purchase a variety of goods and services.
Consider examples such as how Discovery’s Vitality weaves together healthcare, lifestyle brands and financial services, then think about how they might evolve in a digital world. Brands have long cooperated through strategies such as white label products, sponsorship agreements and distribution deals, but the next wave of digital change will take it to a new level.
As this shakes out in the years to come, brands will need to focus on building a technical architecture that enables them to rapidly partner with other brands to roll out innovative solutions and services. They will also need to consider how and where they will capture customer data and which touchpoints they can use to own the customer relationship.
The challenges will not be purely technical in nature. There is the human element of blending AI and people into ‘teams’ that deliver the best possible customer experience. Companies will also need to think about their business models and where they fit into the value chain. Those that align AI and data behind a coherent business strategy will be the ones who will win the first digital mile.
