Storage improves surveillance

Published

on

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.

Samsung S10 in lock-step with its rivals?

Tonight Samsung will kick off the next round in the smartphone wars with the S10 range, writes ARTHUR GOLDSTUCK.

Published

on

When Samsung unveils the new S10 smartphone at an event in San Francisco today, it will mark the beginning of the 2019 round of World War S. That stands for smartphone wars, although Samsung would like it to be all about the S.

Ever since the launch of the Samsung Galaxy S4 in 2013, Samsung has held both technology and thought leadership in the handset world. Back then, Apple’s iPhone 5 was the last device from the American manufacturer that could lay claim to being the best smartphone in the world. With the 2013 launch of the iPhone 5s, Apple entered an era of incremental improvement, playing catch-up, and succumbing to market trends driven by its competitors.

Six years later, Samsung is fighting off the same threat. Its Chinese rival, Huawei, suddenly wrested away leadership in the past year, with the P20 Pro and Mate 20 Pro regarded as at last equal to the Samsung Galaxy S9 Plus and Galaxy Note 9 – if not superior. Certainly, from a cost perspective, Huawei took the lead with its more competitive prices, and therefore more value for money.

Huawei also succeeded where Apple failed: introducing more economical versions of its flagship phones. The iPhone 5c, SE and XR have all been disappointments in the sales department, mainly because the price difference was not massive enough to attract lower-income users. In contrast, the Lite editions of the Huawei P9, P10 and P20 have been huge successes, especially in South Africa.

Today, for the first time in half a decade, Samsung goes into battle on a field laid out by its competitors. It is expected to launch the Galaxy S10 Plus, S10 and S10 e, with the latter being the Samsung answer to the strategy of the iPhone XR and Huawei P20 Lite.

Does this mean Samsung is now in lock-step with its rivals, focused on matching their strategies rather than running ahead of them?

It may seem that way, but Samsung has a few tricks up its electronic sleeve. For example, it is possible it will use the S10 launch to announce its coming range of foldable phones, expected to be called the Galaxy X, Galaxy F, Galaxy Fold or Galaxy Flex. It previewed the technology at a developer conference in San Francisco last November, and this will be the ideal moment to reclaim technology leadership by going into production with foldables – even if the S10 range itself does not shoot out the lights.

However, the S10 handsets will look very different to their predecessors. First, before switching on the phone, they will be notable by the introduction of what is being called the punch-hole display, which breaks away from the current trend of having a notch at the top of the phone to house front-facing cameras and speakers. Instead, the punch-hole is a single round cut-out that will contain the front camera. It is the key element of Samsung’s “Infinity O” display – the O represents the punchhole – which will be the first truly edge-to-edge display, on the sides and top.

The S10 range will use the new Samsung user interface, One UI, also unveiled at the developer conference. It replaces the previous “skin”, unimaginatively called the Samsung Experience, to introduce a strong new interface brand.

One UI went live on the Note 8 last month, giving us a foretaste, and giving Samsung a chance to iron out the bugs in the field. It is a less cluttered interface, addressing one of the biggest complaints about most manufacturer skins. Only Nokia and Google Pixel handsets offer pure Android in the local market, but One UI is Samsung’s best compromise yet.

It introduces a new interaction area, in the bottom half, reachable with the thumb, with a viewing area at the top, allowing the user to work one-handed on the bottom area while still having apps or related content visible above. One UI also improves gesture navigation – the phone picks up hand movements without being touched – and notification management.

The S10 range will be the first phones to feature the latest Qualcomm Snapdragon 855 chip, at least for the South African and American markets. That makes it 5G compatible, for when this next generation of mobile broadband becomes available in these markets.

They will also be the first phones to feature Wi-Fi 6, the next generation of the Wi-Fi mobile wireless standard. It will perform better in congested areas, and data transfer will be up to 40% faster than the previous generation.

The phones will be the first to use ultrasound for fingerprint detection. If Samsung gets it right, this will make it the fastest in-screen fingerprint sensor on the market, and allows for a little leeway if one pushes the finger down slightly outside the fingerprint reader surface. It does mean, however, that screen protectors will have to be redesigned to avoid blocking the detection.

Not enough firsts? There are a few more.

Most notably, it will be the first phone range to feature 1 Terabyte (TB) storage – that’s a thousand Gigabytes (GB) – at least for the top-of-the-range devices. Samsung last month announced that it would be the first manufacturer to make 1TB built-in onboard flash storage. Today, it will deploy this massive advantage as it once again weaponises its technology in the fight for smartphone domination.

IoT set to improve authentication

Published

on

By Sherry Zameer, Senior Vice President, Internet of Things Solutions for CISMEA region at Gemalto

As it rapidly approaches maturity, the Internet of Things (IoT) is set to continue a transformational trajectory, introducing new efficiencies in multiple fields by allowing measurement and analysis on a scale that has never been possible before. From agriculture to logistics, from retail to hospitality, from traffic to health, from the home to the office, the applications for monitoring ”things” are limited only by the imagination.

And South African (and African) businesses are showing abundant imagination in their practical deployments of IoT solutions in multiple settings, creating a better tomorrow through almost universal measurement and the introduction of new levels of convenience – including how to access locations, devices and services securely.

Any company, whether South African or international, should bear in mind that understanding consumer expectations can be the key to unlocking the full potential of IoT devices and related smart services.

According to Gemalto’s latest Connected Living study, improving the way consumers authenticate themselves to services is one of the most anticipated benefits of IoT, highlighting a desire for a more seamless and secure IoT experience.

Consumers are interested in advanced ways of authenticating themselves through automatic (based on behavioral patterns) or biometric techniques, lessening the need to have to intervene manually, all in the name of a much more streamlined authentication process. Smartphone manufacturers like Apple and Samsung have already placed fingerprint and facial recognition high on the agenda. There is also a widespread positive sentiment towards IoT’s potential for improving the quality of home life through connected, smart appliances.

Personalised services is something else that wins consumers over. In fact, a fluid, personalised and unified experience with continuity of services, together with security and privacy, is critical for the successful implementation of any technology.

And those types of services are today quite possible. With everything being connected – from small gadgets to digital solutions for large enterprises – IoT is no longer just a buzzword. That much is clear in a piece from Vodacom IoT managing executive Deon Liebenberg. Writing for IOL Online, Liebenberg provides insight into the sheer range of applications for IoT: the 20 use cases he cites range from the obvious, like transport and logistics, to the connected home and wearables; he even suggests tagging pets with IoT transmitters, for those who always need to know the whereabouts of the family cat.

Low-cost tags fitted to cats, dogs, lamp posts, shipping containers or other items are just one part of the puzzle, however. There are other two pieces; arguably the most complex part is the availability of communication networks in areas where there aren’t any WiFi networks, or indeed, anything else.

And that’s where the bigger takeaway from Liebenberg’s piece and other IoT trends articles becomes apparent. The communication networks are there, as are those tags: dedicated IoT networks (like LoraWAN, SigFox and narrowband IoT) are all available in South Africa.

So, too, is the third and final essential component. Software which is able to process the data generated by the tag and transmitted over the IoT network and into the internet. In this regard, there’s no shortage of solutions available from cloud providers like AWS and Azure; electronics giant Siemens, too, is in on the action, having recently launched a new cloud-based IoT operating system to develop applications and services for process industries, including oil and gas and water management.

This combination means it is quite possible right now to enable just about any use case. Business owners, who will know best how IoT can add value in their organisation, can now see their ideas becoming reality. Most crucial of all, IoT solutions delivering new levels of efficiency and convenience are not only possible, they are able to be offered with the simple and effective security that will drive consumer acceptance.
