This article originally appeared on ABACUS The future of ZTE is still up in the air -- and now another Chinese tech giant could end up on the US blacklist. Hikvision is the second biggest vendor of surveillance products in the US . Its cameras have been widely used around the country , installed in schools and prisons -- as well as an army base in Missouri, and as far as the US embassy in Kabul, Afghanistan. The company is now crying foul, after the US House of Representatives passed a bill banning the federal government from buying equipment from Hikvision and several other Chinese companies, citing national security concerns. Representative Vicky Hartzler , who proposed the ban, said, “We must face the reality that the Chinese government is using every avenue at its disposal to target the United States, including expanding the role of Chinese companies in the US domestic communications and public safety sectors.” She said her amendment will “ensure that China cannot create a video surveillance network within federal agencies.” On its official Weibo account , Hikvision said the accusations carried “obvious speculation and bias”. And a Hikvision executive reportedly posted a statement on WeChat , saying that the company welcomes the US government to visit its lab in Los Angeles and examine the products’ source codes. Hikvision has attracted scrutiny in the US over its ties to the Chinese government, which owns 42% of the company. Its head of research and development also leads a lab inside China’s Ministry of Public Security. Missouri’s Fort Leonard Wood army base has said that any equipment used on a US military network is thoroughly tested for security vulnerabilities. But it decided to replace Hikvision cameras in January to “avoid negative perception”. The potential ban also covers two other Chinese surveillance product makers, Dahua and Hytera, as well as telecom giants ZTE and Huawei. How a US ban on Huawei could affect consumers A similar bill still needs to go through the Senate. If it passes, President Donald Trump will decide whether to sign it into law.
