Exclusive: Amazon turns to Chinese firm on U.S. blacklist to meet thermal camera needs

NEW YORK/SAN FRANCISCO (Reuters) – Amazon.com Inc (AMZN.O) has bought cameras to take temperatures of workers during the coronavirus pandemic from a firm the United States blacklisted over allegations it helped China detain and monitor the Uighurs and other Muslim minorities, three people familiar with the matter told Reuters.

China’s Zhejiang Dahua Technology Co Ltd (002236.SZ) shipped 1,500 cameras to Amazon this month in a deal valued close to $10 million, one of the people said. At least 500 systems from Dahua – the blacklisted firm – are for Amazon’s use in the United States, another person said.

The Amazon procurement, which has not been previously reported, is legal because the rules control U.S. government contract awards and exports to blacklisted firms, but they do not stop sales to the private sector.

However, the United States “considers that transactions of any nature with listed entities carry a ‘red flag’ and recommends that U.S. companies proceed with caution,” according to the Bureau of Industry and Security’s website. Dahua has disputed the designation.

The deal comes as the U.S. Food and Drug Administration warned of a shortage of temperature-reading devices and said it wouldn’t halt certain pandemic uses of thermal cameras that lack the agency’s regulatory approval. Top U.S.-based maker FLIR Systems Inc (FLIR.O) has faced an up to weeks-long order backlog, forcing it to prioritize products for hospitals and other critical facilities.

Amazon declined to confirm its purchase from Dahua, but said its hardware complied with national, state and local law, and its temperature checks were to “support the health and safety of our employees, who continue to provide a critical service in our communities.”

The company added it was implementing thermal imagers from “multiple” manufacturers, which it declined to name. These vendors include Infrared Cameras Inc, which Reuters previously reported, and FLIR, according to employees at Amazon-owned Whole Foods who saw the deployment. FLIR declined to comment on its customers.

Dahua, one of the biggest surveillance camera manufacturers globally, said it does not discuss customer engagements and it adheres to applicable laws. Dahua is committed “to mitigate the spread of the COVID-19” through technology that detects “abnormal elevated skin temperature — with high accuracy,” it said in a statement.

The U.S. Department of Commerce, which maintains the blacklist, declined comment. The FDA said it would use discretion when enforcing regulations during the public health crisis as long as thermal systems lacking compliance posed no “undue risk” and secondary evaluations confirmed fevers.

Dahua’s thermal cameras have been used in hospitals, airports, train stations, government offices and factories during the pandemic. International Business Machines Corp (IBM.N) placed an order for 100 units, and the automaker Chrysler placed an order for 10, one of the sources said. In addition to selling thermal technology, Dahua makes white-label security cameras resold under dozens of other brands such as Honeywell, according to research and reporting firm IPVM.

Honeywell said some but not all its cameras are manufactured by Dahua, and it holds products to its cybersecurity and compliance standards. IBM and Chrysler’s parent Fiat Chrysler Automobiles NV (FCHA.MI) did not comment.

The Trump Administration added Dahua and seven other tech firms last year to the blacklist for acting against U.S. foreign policy interests, saying they were “implicated” in “China’s campaign of repression, mass arbitrary detention, and high-technology surveillance against Uighurs, Kazakhs, and other members of Muslim minority groups.”

More than one million people have been sent to camps in the Xinjiang region as part of China’s campaign to root out terrorism, the United Nations has estimated.

Dahua has said the U.S. decision lacked “any factual basis.” Beijing has denied mistreatment of minorities in Xinjiang and urged the United States to remove the companies from the list.

A provision of U.S. law, which is scheduled to take effect in August, will also bar the federal government from starting or renewing contracts with a company using “any equipment, system, or service” from firms including Dahua “as a substantial or essential component of any system.”

Amazon’s cloud unit is a major contractor with the U.S. intelligence community, and it has been battling Microsoft Corp (MSFT.O) for an up to $10 billion deal with the Pentagon.

Top industry associations have asked Congress for a year-long delay because they say the law would reduce supplies to the government dramatically, and U.S. Secretary of State Mike Pompeo said last week that policies clarifying the implementation of the law were forthcoming.

FACE DETECTION & PRIVACY

The coronavirus has infected staff from dozens of Amazon warehouses, ignited small protests over allegedly unsafe conditions and prompted unions to demand site closures. Temperature checks help Amazon stay operational, and the cameras – a faster, socially distant alternative to forehead thermometers – can speed up lines to enter its buildings. Amazon said the type of temperature reader it uses varies by building.

To see if someone has a fever, Dahua’s camera compares a person’s radiation to a separate infrared calibration device. It uses face detection technology to track subjects walking by and make sure it is looking for heat in the right place.

An additional recording device keeps snapshots of faces the camera has spotted and their temperatures, according to a demonstration of the technology in San Francisco. Optional facial recognition software can fetch images of the same subject across time to determine, for instance, who a virus patient may have been near in a line for temperature checks.

Amazon said it is not using facial recognition on any of its thermal cameras. Civil liberties groups have warned the software could strip people of privacy and lead to arbitrary apprehensions if relied on by police. U.S. authorities have also worried that equipment makers like Dahua could hide a technical “back door” to Chinese government agents seeking intelligence.

In response to questions about the thermal systems, Amazon said in a statement, “None of this equipment has network connectivity, and no personal identifiable information will be visible, collected, or stored.”

Dahua made the decision to market its technology in the United States before the FDA issued the guidance on thermal cameras in the pandemic. Its supply is attracting many U.S. customers not deterred by the blacklist, according to Evan Steiner, who sells surveillance equipment from a range of manufacturers in California through his firm EnterActive Networks LLC.

“You’re seeing a lot of companies doing everything that they possibly can preemptively to prepare for their workforce coming back,” he said.

Chinese scientists create tiny battery capable of working in ultra-low temperatures

  • Team from Dalian Institute of Chemical Physics says its goal is to ‘develop an all-season battery that is low cost but high safety for consumer products’
  • Researchers make breakthrough by using hard carbon and lithium vanadium phosphate

Chinese researchers say they have found a way to produce a tiny, lightweight lithium battery for use in mobile phones and electric cars that can hold up to 80 per cent of its charge in temperatures as low as minus 40 degrees Celsius.

The breakthrough came by using a combination of a new material called hard carbon along with lithium vanadium phosphate, the team from the Dalian Institute of Chemical Physics said in a paper published in this month’s edition of the scientific journal Nano Energy.

“Our goal is to develop an all-season battery that is low-cost but high-safety for consumer products,” said Song Zihan, its lead author.

It was an unprecedented approach, but “we proved it works”, he said.

The idea of a battery that can withstand extreme cold is not new, and they are already in use in space and in the Arctic and Antarctic.

But they tend to be very bulky because of the heating system and large amount of insulation they need to function properly at sub-zero temperatures.

Such measures are neither physically nor economically viable for applications like smartphones, cameras, laptops or electric cars. The trick, Song said, was replacing the soft graphite in normal lithium batteries with hard carbon.

Graphite is a good conductor and often used for the anode at the bottom of a battery, where electrons are generated. But the performance of graphite drops as the mercury slides.

Song said that hard carbon was a new material that had attracted a lot of research interest in recent years, and compared with graphite, it had a much higher tolerance for the cold.

That was because of its highly irregular and “almost messy” structure, comprising layers of carbon atoms that are interconnected with each other, he said.

However, hard carbon also caused a rapid depletion of the lithium ions that served as an agent carrying the electric flow in battery, he said.

In the past, researchers have tried adding lithium powders or flakes to improve battery life, but the approach has proven costly and dangerous, mostly because pure lithium is highly reactive.

So Song and his colleagues used a composite material called lithium vanadium phosphate as the positive cathode on top of the battery.

The composite was capable of providing enough extra lithium ions for the hard carbon’s need without increasing the risk of fire or explosion, and it was cheap, he said.

“The pairing of hard carbon and lithium vanadium phosphate worked a charm,” Song said.

But the technology is still a long way from being commercially viable.

The battery Song’s team made is far too small for any real-life applications, and enlarging it would require some “innovative engineering solutions”, he said.

Another scientist involved in the project said the team was working with battery manufacturers to see if the technology could be commercialised.

iPhone 11: Will Apple’s latest phones capture India’s growing market?

Apple has unveiled its iPhone 11 range of handsets, featuring more cameras and more battery life. But will it be enough to capture one of the world’s only growing smartphone markets?

Samsung has traditionally held dominance in the Indian “premium smartphone” segment, which refers to mobiles that cost 40,000 rupees (£451; $558) or more.

But this year, for the first time ever, Apple surged ahead of the Korean electronics giant in India. It swept up 41.2% of the premium smartphone market in the second quarter of 2019, according to research firm International Data Corporation.

“The Indian smartphone market is a game of changing fortunes,” technology journalist Mala Bhargava told the BBC. “There isn’t a company, no matter how dominant a position it commands, that can afford to sit idle.”

Apple’s latest mobile phones – the iPhone 11, 11 Pro and 11 Pro Max – will be available in India from 27 September.

And the iPhone 11, Ms Bhargava added, is primed to find success in the Indian market.

In recent months, Apple dropped its price for the iPhone 11’s predecessor, the iPhone XR, from 73,900 rupees to 53,900 rupees. The 20,000 rupee price drop was significant enough to make an impact.

“Consumers in India are known to be discount and deal-oriented,” Ms Bhargava said. “Seeing the iPhone as an aspirational product, many snapped up the mobile once prices were slashed.”

This, she said, is also what gave Apple the lead for the first time in India in the smartphone market.

The latest iPhones feature more cameras than before and a processor that has been updated to be faster while consuming less power. There are two Pro models, which the company said would last between four to five hours longer than their XS predecessors.

The entry-level iPhone 11 is the “perfect successor” to the iPhone XR, Ms Bhargava said.

It will start at a price of 64,900 rupees – which is not drastically higher than what the iPhone XR currently sells for.

“The discounted iPhone XR played a big part in bolstering sales in India, so it’s likely that with such a price for the iPhone 11, the company can really extend its market share,” she added.

Apple also launched the iPhone 11 Pro and iPhone 11 Pro Max, which at 99,990 rupees and 109,900 rupees a piece, will not be a key attraction as consumers will find that unaffordable.

“But at the same time, this gap could still benefit the company, leaving the field open for older iPhones and for the new iPhone 11 to increase Apple’s share in the country,” Ms Bhargava said.

The company is still selling the iPhone XR, along with the older iPhone 8, which will give consumers more choices and prices to choose from.

“With the sales of smartphones falling in the rest of the world, Apple can’t help but look to consolidate its position in India – it is almost the only market growing at an enthusiastic pace,” she added.

In the second quarter of 2019, 36.9 million handsets were shipped in India – up 9.9% from last year.

In comparison, the premium global smartphone market collapsed 8% in the first quarter this year, with much of the decline pushed by a 20% drop in Apple’s shipments.

“India still has millions of first-time phone buyers,” said Ms Bhargava, “and many of those who have been using budget phones are read to buy something better.”
