TV360 Box mis-identified on WiFi?

I have to admit to being perhaps more than a little paranoid about IT security, so when I saw an unknown device, titled "HUMAX NETWORKS", on my WiFi network, I immediately blocked it and started trying to figure out how someone outside of the house might have gained access.

A few minutes later, the blocked item was relabelled as my main TV360 box and this was confirmed by that box no longer being connected to the Internet.  

Panic over and I've now unblocked it, but wondered if this is likely to be an issue with my router or whether the TV360 boxes might have some historical connection to Humax, that might explain this mis-identification?
