Does Zkteco Make Its Own IP Cameras?

For those of you that can spot an OEM'd camera just by looking at them, could you please take a look at the network cameras on the ZKTeco website and tell me if they appear to be made by Hik/Dahua/Uniview?

I believe ZK states that they make their own cameras, which I can believe if that's the case since they do have ample production resources and capacity for manufacturing them.

Thanks in advance.
