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.
Huawei Mate 20 Pro matches camera benchmark record
A benchmark by DxOMark sees the triple-cam handset tie with the P20 Pro for best smartphone camera on the market.
The Huawei Mate 20 Pro has come out top in a camera benchmark test that assesses all aspects of smartphone camera performance.
DxOMark, which conducts rigorous hardware testing and is trusted as an industry standard for image quality measurements, has just released the results of its in-depth analysis of the Huawei Mate 20 Pro smartphone camera.
The Huawei Mate 20 Pro is the Chinese manufacturer’s latest top-end device. Building on the P20 Pro’s camera technology, the Mate 20 Pro comes with a Leica-branded triple-camera setup, but swaps its stable-mate’s monochrome camera for a super-wide-angle module, offering a 35mm-equivalent focal length range from 16 to 80mm—the widest of all current smartphone cameras.
The handset is in direct competition with the Apple iPhone XS Max, the Google Pixel 3 XL, the Samsung Galaxy Note 9, among other. How does it fare?
“With a total photo score of 114, the Huawei Mate 20 Pro ties the record-setting score of its cousin, the P20 Pro,” says DxOMark. “The overall Photo score is calculated from sub-scores in tests that examine different aspects of its performance under different lighting conditions.”
The Huawei Mate 20 Pro achieves a photo score of 114 points. In stills mode, the Mate 20 Pro’s triple camera captures images with good target exposure and a wide dynamic range, recording both good highlight and shadow detail even in difficult high-contrast situations. Noise levels are well under control down to low light levels, and the camera’s white balance system and colour rendering settings produce a pleasant colour response in almost all circumstances.
At 97 points, the Mate 20 Pro is very close to the best for video as well, thanks to a fast and smooth autofocus system with good tracking performance, accurate white balance as well as pleasant colour rendering, and low levels of noise, especially in bright shooting conditions. Our testers also liked the exposure system’s ability to adapt quickly and smoothly to changes in illumination.
It was not all good news. DxOMark also had some criticism for the device.

SA car wins
The final stage of Dakar 2019 drew to a close at the bivouac in Pisco, Peru, and saw Toyota Gazoo Racing South Africa’s Nasser Al Attiyah and Mathieu Baumel bring home their South African-built Toyota Hilux for
The Qatari driver ensured his French navigator, who turned 43 years old on Thursday, 17 January, received a great birthday present, when the pair arrived at the final time control of Dakar 2019 with teammates Giniel de Villiers and Dirk von Zitzewitz in close formation. The two Toyota Hilux crews completed the entire stage together, as De Villiers / Von Zitzewitz waited nearly 55 minutes for the leaders to start the stage, in order to shadow them to the finish.
The emotions bubbled over for Team Principal Glyn Hall, who found himself without words as his two crews drove into the media area after the time control. “This victory was long overdue,” he finally managed, before being swamped in a sea of well-wishers.
The winning driver, however, was much more vocal: “We are so happy to win the Dakar – not only for ourselves, but also for Toyota and the entire Toyota Gazoo Racing SA team. Everyone has worked so hard for so long, and really deserve this. Thank you for letting us drive this car.”
Toyota Gazoo Racing SA led Dakar 2019 from the first to the last stage, with Al Attiyah/Baumel drawing first blood, before handing the mantle to De Villiers / Von Zitzewitz during stage 2. But then a disastrous Stage 3 saw the Qatari retake the lead – a lead he didn’t relinquish despite some of the toughest stages yet seen on any South-American Dakar.
“When we first heard that the rally was going to take place only in one country, we were skeptical,” said Hall after regaining composure. “But the organisers made sure that this year’s race will long be remembered as one of the toughest tests in the last decade.”
Al Attiyah / Baumel’s victory at Dakar 2019 means that Toyota Gazoo Racing has now won both of the world’s toughest automotive races – the 24 Hours of Le Mans, and the DakarRally.
