As you’re walking along the street, China‘s newest surveillance technology could soon be watching you – from space.
Scientists in Beijing have created ‘the world’s most powerful spy camera’ which can pick out facial details from distances exceeding 63 miles (100km).
It means the spy camera could potentially be in space aboard a floating satellite while clearly seeing faces of people on Earth’s surface.
It could also take high-resolution images of foreign military satellites operated by other nations that are also orbiting Earth, the South China Morning Post reported.
The technology, detailed by the scientists in a new paper, could be launched aboard a satellite in the near future.
But, unsurprisingly, the powerful laser-based system has sparked worries.
Robert Morton, author and member of the Association of Former Intelligence Officers (AFIO), called it a ‘massive security concern’.
‘Millimeter resolution from 60+ miles up? That’s next-level surveillance,’ he said in a post on X (Twitter).

Meanwhile, Julia Aymonier, head of digital transformation at API, posted to LinkedIn: ‘Big Brother is watching you!’
She added: ‘The future of space-based surveillance is here, and it’s more powerful than we imagined.’
And Natallia Catarina, CEO at Beam Wallet, said: ‘Now only clouds will save us from Chinese spies.’
The spy camera has been newly developed by China’s Academy of Sciences’ Aerospace Information Research Institute in Beijing.
It uses a system called synthetic aperture lidar (SAL), a remote sensing technology that sends out a pulse of light energy and then records the amount of that energy reflected back.
Capable of operating day and night, SAL creates 2D and 3D reconstructions of surfaces of the Earth in various weather conditions.
Because it relies on optical waves, it’s capable of creating imagery with much finer resolution and better detail – described as a ‘quantum leap’.
The experts conducted a successful test across Qinghai Lake in China’s northwest, with the SAL device on one side and the target 63.2 miles (101.8km) away.

They achieved ‘exceptional’ imaging clarity at this distance, as reported by South China Morning Post, which is around about where the boundary of space starts.
Alarmingly, the device detected details as small as 0.07 inches (1.7mm) and measured distances to within 0.61 inches (15.6mm).
Live Science points out that SAL needs the motion of an object – such as a moving satellite in orbit – to get images with finer resolution.
So the spy camera would need to be mounted on a satellite of China’s or even its Tiangong Space Station, the rival to the ISS launched in 2021.
Tiangong is moving at 17,000 miles per hour while in low Earth orbit, between 210 and 280 miles (340 and 450km) above our planet’s surface.
China already operates around 300 other surveillance satellites in lower orbits, according to the Center for Strategic & International Studies.
For example, Yaogan-41 – launched in December 2023 – gives China the ability to ‘identify and track car-sized objects throughout the entire Indo-Pacific region’.
It’s unclear when the world’s most powerful spy camera could be launched: MailOnline has contacted the researchers for more information.

The researchers outline their work further in a new study published in the Chinese Journal of Lasers.
China has previously raised US concerns through its use of ‘spy balloons’, which the Asian country has insisted are simply devices for monitoring the weather.
China’s government has come under increasing scrutiny for high-tech surveillance, from facial recognition-enabled security cameras to apps used by police to extract personal information from smartphones at checkpoints.
China is famous for tracking its citizens using the latest technology – notably a Black Mirror-like social rating system to ‘restore morality’ and blacklist ‘untrustworthy’ citizens.
It also reportedly developed an AI that can read the minds of Communist Party members by analysing facial expressions and brain waves.
