South Australia’s health department is removing from its buildings all closed-circuit television cameras made by a Chinese surveillance giant due to security concerns.

The department will remove all cameras made by Hikvision, a partially state-owned Chinese surveillance technology company, from its public hospitals and nursing homes.

But despite the warnings, Hikvision cameras continue to operate in other government buildings across the country, including NSW health facilities where there is no plan to remove them.

Victoria and Queensland refused to say whether there were Hikvision cameras in their public hospitals or aged care centres.
