“It has come at a cost to our business, but it does allow us to sleep at night.”

That’s the view of Daniel Lewkovitz, CEO of Calamity Monitoring – an Australian security company that’s pulled the plug on its ties with Chinese firm Dahua.

Mr Lewkovitz made the decision when he found a function in Dahua’s technology that enabled it to racially profile people, such as the Uighurs.

He’s urged other companies to follow suit, as Phoebe Bowen reports.
