In August 2018, the US Congress officially passed the 2019 national defense authorization act, which banned federal government agencies from purchasing products of several Chinese enterprises, including monitoring equipment manufacturers Hikvision and Dahua, on the grounds of "national security considerations" < p > after nearly three years, the interceptor, a US investigative news website, published a report on July 21 local time entitled "the US military purchased cameras in violation of US sanctions against China", which revealed the fact that many US federal agencies, including military branches, purchased monitoring equipment from Hikvision and Dahua < p > "interceptor" and a video surveillance industry research publication media "ipvm" after a joint investigation, it was learned that these institutions purchased blacklisted Chinese enterprises' equipment through a domestic dealer network system in the United States, and the dealers said that these cameras were compliant < p > after appearance comparison and even professional disassembly comparison, it is found that many other brands of equipment are actually products of Hikvision or Dahua, and ipvm even found the processor manufacturing label of "Huawei (Hisilicon)" in a device < p > after this situation was exposed, from the federal online sales platform responsible for government procurement, to a number of federal distribution contractors, and finally to the U.S. military that actually purchased products, their responses were basically vague, not focused on the key points, and some even appeared the saying of "shirking the blame and throwing the pot" < p > at the same time of the investigation report, the federal surveillance camera suppliers mistakenly contacted the investigation media, hoping that they could help to provide Hikvision equipment and install it in the US embassy in Venezuela < p > < p > screenshot of interceptor's report < / P > < p > I don't know if I don't dismantle it, but I'm scared when I dismantle it... < / P > < p > according to interceptor's report, publicly available purchase records show that since the US initiated sanctions, including the US air force, the army, the Navy, the Department of Veterans Affairs and the office of the Secretary of defense, they have purchased products from two Chinese companies, Hikvision and Dahua, The other camera system hardware purchased, confirmed by ipvm, is actually assembled or manufactured by Hikvision and Dahua, and finally sold in the name of other brands < p > GSA is responsible for government procurement, and its "GSA advantage" is a platform for federal suppliers to sell products to the government online. The list released by this platform also shows that the renamed Hikvision and Dahua equipment can still be purchased under different brand names < p > this report describes in detail how these cases were discovered: Although these devices are not sold in the name of the two sanctioned Chinese enterprises, ipvm compares them with similar devices of the sanctioned companies in terms of hardware and software appearance, and in some cases, compares the devices after physical disassembly < p > for example, the recently launched "performance" series of surveillance cameras on the "GSA advantage" platform is ostensibly made by Honeywell, a major US defense contractor, but they are no different from Dahua's equipment in appearance. The software interface of the two cameras is almost identical. After partial disassembly of Honeywell's equipment, it was also found that a silicon processor also had a "Huawei (Hisilicon)" processor manufacturing label on it < p > when the Honeywell equipment was disassembled, there was a picture of the processor manufacturing label of Huawei's Hisilicon semiconductor company. From ipvm < / P > < p > < p > "interceptor" pointed out that since the US government did not provide the public with any evidence to prove that Hikvision and Dahua "monitored customers", this severe sanction has been questioned in terms of investigation procedure, transparency and seriousness. At the same time, it is not clear to the outside world how the US government effectively regulates the products on "GSA advantage", which has a large number of products available for sale < p > when the news is exposed, how do all parties respond < p > in an email in response to interceptor, GSA spokesman Kim armeni said that their contractors were required to comply with the Federal Acquisition regulations (far), which set rules for government procurement and contracting practices. In the 2019 update, the ban on Hikvision and Dahua under the defense authorization act was also included < p > armney said that GSA has a variety of methods to review the suppliers on its platform and the products they sell, but did not elaborate on these methods < p > according to the public purchase records and the analysis results of ipvm, the US Army purchased a Dahua video recorder, model "xvr4104", brand "amcrest" and model "amdv10814-1tb-c", which was resold by Global Data Center Inc. under the certification of the supplier in September 2020 < p > compared with the two models, only the appearance and decoration are slightly different. Although the front panel of "amcrest" version seems to be modified, both models have the same side ventilation panel, and the interface arrangement of the rear section is also the same, which indicates that they use the same internal circuit. In addition, the two devices are equipped with almost the same software, but "amcrest" has added some new color elements to its version < p > the comparison shows that Honeywell's "performance" surveillance camera uses a miniaturized customized version of ipvm with Dahua's built-in software interface < / P > < p > in response to this situation, Chris Davis, vice president of global data center, replied by e-mail: "we have both fault and no fault in this issue. We don't know that amcrest or Bosch are selling and shipping anything other than the products they're selling. " "If they transport banned third-party products, this is done without our knowledge, consent or approval," he added < p > Davis also said that he had learned some information from GSA and was cooperating with GSA to provide all the information to clearly prove that the company had no relationship with this incident and was not involved in any incident < p > "amcrest's cameras and security products are designed by the brand's company in Houston, Texas, and work with contract manufacturers (Mexico and China) around the world to complete the design, assembly and actual manufacturing," a representative of amcrest wrote in an email The representative acknowledged that the company's products did not comply with the provisions of the defense authorization act, which meant that they could not be legally sold to the federal government < p > Anne insero, spokesman of Bosch(Anne insero) said that the global data center company purchased those video products through distributors, and Bosch has no direct purchasing relationship with the company. "We are transparent about any customer inquiries about compliance with the defense authorization act," the spokesman added Richard Levine, a spokesman for the US Army, who purchased the products, replied in an email: "companies applying for federal contracts must comply with various federal acquisition regulations and defense supplements. The equipment was purchased through the GSA website. It is a video recorder. The procurement team found that neither amcrest nor GDC are listed as prohibited companies, and there is no evidence that they may be related to the prohibited companies. " < p > in addition to the US Army, the US Air Force has also been found to have purchased Dahua's cameras and Hikvision's surveillance camera system. The spokesman responded that the military will conduct an investigation, but there is no latest progress available to publish < p > in the process of interceptor's investigation and report, the suspected "violation" of the US Defense Authorization Act is still happening. A federal surveillance camera supplier contacted ipvm, and it is obvious that they mistook the monitoring industry research publication media for a camera dealer. The supplier asked ipvm if it could provide four Hikvision surveillance cameras to be installed in the US embassy in Venezuela The U.S. Department of state's foreign security service declined to comment on the situation In 2018, the US Congress passed legislation to prohibit federal agencies from purchasing equipment produced by several Chinese companies, including Hikvision and Dahua, on the grounds of "national security considerations"; On October 8, 2019, the US Department of Commerce once again listed eight Chinese enterprises, including Hikvision and Dahua, on the "blacklist" of trade control, and prohibited US enterprises from cooperating with listed institutions < p > before the US investigation media interceptor exposed these news, the Wall Street Journal reported on October 19, 2019 that there were still more than 2700 Chinese made cameras operating in US federal agencies. According to the report, the number of cameras actually installed and still working may be higher "since forecout can't get all the data" At the same time, other Western media are also hyping the so-called "security threat" of Chinese surveillance cameras

6 28, the former Broadcasting British Corporation (BBC) employee Natalia Antrava (Natalia Antelava) founded the news platform "Koda" (Coda Story) reported that although the United States unwarranted suppression of Hikvision, but in the COVID-19 period, the administrative regions and schools at all levels in the United States have spent hundreds of thousands of dollars to buy Hikvision's temperature scanning cameras. At present, the United States estimates that there are more than 330000 monitoring equipment of Hikvision < p > in addition to the United States, Britain also uses a large number of Hikvision equipment. According to a survey by Internet research firm top10vpn, about 65% of local governments in the UK currently use Hikvision technology and have purchased at least $1.3 million worth of equipment in the past two years. Britain has become the fourth largest foreign buyer of Hikvision in the world At the end of June this year, Matt Hancock, the British health secretary, was monitored and photographed cheating in marriage, which caused strong repercussions in China, and then he resigned. Unexpectedly, some British media and politicians have also dumped the "pot" on the surveillance cameras produced by Chinese company Hikvision < p > in addition to the frequent crackdown on Hikvision and Dahua, on July 9, the US Department of Commerce added 23 Chinese entities to the "entity list" of export control In response, a spokesman for China's Ministry of Commerce said that the US side generalized the concept of national security, abused export control measures, ignored the facts, and once again listed 23 Chinese entities on the "entity list" on the grounds of so-called "human rights". This is an unreasonable crackdown on Chinese enterprises and a serious violation of international economic and trade rules, which China firmly opposes. The US side should immediately correct the wrong practice. We will take necessary measures to resolutely safeguard China's legitimate rights and interests
