They have made it clear it is a China / PRC government issue, ergo why Huawei was removed too.
As you know, unlike Hikvision, Huawei is not owned by the Chinese Government, on paper at least. Rather, its structure is an ESOP, like Dahua.
Yes, Wikileaked documents contain statements regarding doubts about where the true control lie and whether backdoors may have been installed. This led to an informal ban on Huawei telcom products, though it should be noted no actual legal sanction was put in place.
In any event no evidence of backdoor was ever found, as the White House admits. If you can find a U.S agency that claims that Huawei is actually owned by the state, I'd would be interested in seeing it.
All this to say that it makes Genetec's action more undefined, since Hikvision can be explained simply by saying that Hikvision's largest shareholder is the Chinese government. With Huawei, they are making a call on something that there is no consensus about, and certainly no official document or statement to back them up.
Is Huawei controlled by the state? It may be, and as we have discussed before, POEs as well as SOEs in China are all beholden to the state ultimately, though SOEs are much easier to manipulate.
tl;dr;
All this to say that, Genetec should also release its criteria for determing this new class of excluded vendors. Otherwise, we should consider the possibility that Genetec conclude that other POEs, i.e. Dahua et al, could be implicated at any time.
