Powered by machine learning, Chinese innovators find new applications in fast-growing markets.

Most investors in the West have some benign, familiar images when it comes to central technologies like Artificial Intelligence (AI) and machine learning. Self-driving cars by Uber and Google make the evening news, and Facebook seems to have an ever-growing list of friends and article recommendations.

But some of the most significant gains and fastest-growing machine learning and AI markets are thriving worldwide – and mainly under the radar. Driven by domestic security needs, Chinese video surveillance companies heavily rely on and innovate in the AI and machine learning space. These AI cameras are deployed to survey, photograph, and catalog booming urban areas and dissident populations. And these advances are less-talked about for a reason: China is not eager to advertise the growing power and accuracy of its rapidly expanding surveillance state.

A booming market

The surveillance market is expanding rapidly, and the demand is global. Research firm CLSA forecasts the global video surveillance market size to grow from $27 billion in 2018 to $53 billion by 2023 (a Cumulative Average Growth Rate of 14%). AI-powered cameras, meanwhile, will rise from 2% of the market to 19% in that time as cheaper, more powerful technology becomes available. Processor prices are expected to fall from $900 to $230.

According to analysts at Macquarie, China is leading the pack, with a 45% market share for surveillance and the single largest market globally. In addition, they note the country’s innovation is leading the way in the AI era.

The AI prowess has been met with questionable applications. For example, China’s ability and willingness to surveil dissident minorities has been criticized. The controversial ethical use and the growing power of Chinese surveillance technology prompted the US to create a blocklist in 2019. While it limited the number of components US companies could export to Chinese companies, it did little to halt Chinese advances.

Now, investors see the global growth and Chinese technological edge as creating potential investment opportunities.

The key players and valuations

The leaders in the China AI surveillance industry include some publicly traded (listed on the Shanghai stock exchange) companies and some multi-billion Unicorns with some very high-profile investors.

  1. Hikvision ($48 billion market cap): China’s largest surveillance company with a market share of 28%.
  2. Dahua: ($20 billion market cap): China’s second-largest company with a market share of 20%.
  3. SenseTime: ($7.5 billion market cap): Raised more than $3 billion from investors, including Temasek Holdings, Alibaba, SoftBank Vision Fund, and Silver Lake Partners
  4. Megvi: ($4 billion market cap): Raised more than $1.3 billion, including from e-commerce giant Alibaba, GGV Ventures, and sovereign wealth funds of Abu Dhabi and Kuwait

Investment Opportunities

The most accessible investment opportunities for most investors are the two public companies: Hikvision (002415.SZ) and Dahua (002236.CN).

Hikvision is firing on all cylinders, with shares having rallied over 6%. But, unfortunately, claims are also not cheap. The company currently trades at 20 times 2020 analyst estimates.

Analysts at UBS note that investor bullishness on the company’s AI-based business units and innovation are driving factors. In 2019, the company’s AI and surveillance solutions were the fastest-growing portfolio and were expected to be the main driver of growth into 2020. In addition, AI-innovation and vertical expansion – finding new industries and applications for its AI-camera solutions – are crucial for its prospects. Here, the company has a track record of demonstrating new solutions. For example, Hikvision embeds AI algorithms with AI- video and thermometer solutions to prevent fires. As a result, the technology can identify early warning fire signals to detect fires, whereas traditional smoke sensors only offer an alert after fires start.

However, the investment in new technology and products can take a toll on capital expenditures and earnings if not managed aggressively. Investors keep a close eye on this dynamic. Trade wars and tariffs have also boosted input costs in the past. Shares are also subject to the volatility of the Chinese markets.


Dahua is amid retrenchment as management attempts to focus on new, higher-growth industries, analysts at UBS note. Shares reflect uncertainty. The stock has traded off 7% year to date and currently trades at just 14 times 2020 analyst estimates.

In 2019, Dahua decided to downgrade its exposure to small enterprises because of the sector’s low margins and bad cash collection practices. So instead, the company is becoming increasingly aggressive in higher-growth verticals like Energy, Financials, and Transportation.

Management also wants to focus on overseas markets, which currently make up 35% of the company’s business. However, regulatory hurdles in developed markets have made growth challenges. The company’s end-demand stayed flat at 25% in the US and Western Europe through 2019. Instead, the company wants to focus on emerging markets such as Asia and Latin America.

AI product and application growth is also a significant push for Dahua, analysts at Macquarie note. The company increased headcount by 500 in its AI-related business in 2019, focusing on facial and car plate recognition.

The increasing dominance of Hikvison in domestic markets – particularly with government entities – and its growing scale is a mounting risk for investors in Dahua. The company also faces potential margin pressures from trade wars, and shares are subject to the volatility of Chinese markets.



Technology and Components 

Faster and more powerful semiconductors are significant drivers in advancing the utility of surveillance cameras and enabling enhanced AI-functionality.

The industry has traditionally used Graphics Processing Units (GPUs) from market leaders like Nvidia (NVDA) to power its applications, analysts at CLSA note. However, as the size of the markets expands, smaller, more agile upstarts like Hisilicon and Ambarella have started to design custom processors known as Systems-on-a-Chip (SoC) to tackle applications customized for video surveillance.

Software-Defined-Cameras (SDCs) are also growing, as software updates allow for new services and configurations of existing cameras without physical interaction. However, SDCs still face various hurdles, as costs are high and communications network issues can lead to low reliability.

Analysts at  Macquarie note that the technology trajectory of the surveillance industry makes it particularly ripe for disruption based on AI-based solutions at this juncture. And Chinese companies are leading the globe to implement forward-thinking AI applications.

They note that the industry started based on analog technology and was dominated by international players such as Axis, Honeywell, Sony, and Panasonic. As digital technology took hold in all corners around 2010, surveillance products too upgraded from analog to digital. This allowed for greater standardization and made components more generic. This opened the door for local fast-followers like Hikvision and Dahua, with the Chinese government moving aggressively to court local players. As the surveillance sector boomed in China, local players used their clout to dominate supply chains.

This industry evolution has set the stage for what Macquarie analysts see as a fourth wave of evolution for the industry, where AI functionality comes to eclipse traditional surveillance demands like cost and reliability. And with end-to-end solutions now in their grasp, Chinese players are focusing heavily on new recognition applications.

These include cutting-edge features like emotional recognition, where AI technology is touted to be powerful enough to predict a person’s mental state via facial recognition. In addition, Chinese authorities have said that deployment will reduce crime by being able to identify individuals in mental states for potentially criminal behavior. For example, current implementations at customs could identify signs of aggressiveness, nervousness, stress levels, and a person’s potential to attack others.

The edge that Chinese surveillance technology companies have is so potent that it is also shaping standards at the UN.  This sets the stage for China to influence emerging countries increasingly reliant on surveillance tech as they grapple with domestic unrest, urban growth, and cost-efficiency considerations.

The Upshot

China has created a thriving technology ecosystem based on AI-powered surveillance. The landscape includes large, fast-growing, and publicly-traded incumbents and innovative startups that fetch meg-Unicorn valuations.

For investors in the West, the AI sector can be unsavory. Many AI and Machine Learning technology applications have raised significant ethical concerns.

But the technology edge of Chinese companies is authentic – and so is the global market demand. The vast data Chinese companies have amassed on facial recognition alone is key to powering machine learning algorithms and creating a self-reinforcing advantage. While China leads the world in surveillance, other fast-growing emerging economies are sources of booming global demand and are emulating many of Beijing’s creative applications.

As semiconductors and software grow even more powerful, investors should recognize these companies’ opportunities in the years ahead.

Ethical considerations, though, also need to be evaluated as business risks.

The invasiveness of the surveillance capabilities is already causing a backlash – the European Union put a temporary ban on facial recognition in January, for example – and one that could grow.

The rapid rise of Environmental, Social, and Governance (ESG) investing presents another major potential challenge. The assets controlled by investment vehicles attuned to social and financial considerations are exploding. If ethical concerns mount, surveillance technology companies could find many investors turning away – even if they continue to deliver on the bottom line.
