It's probably fair to assume that most of their other camera models are affected by the same or similar issues. It looks like they pump out quite a few models that I image have similar firmware.
This page[1] lists the C200 as last having a firmware update in October, but also lists the latest version as 1.4.4 while the article lists 1.4.2. It seems like they have pushed other updated in this time, but not these security fixes.
I looked at some older Zyxel products and came to the same conclusion a while back. There's a whole industry of labeling generic hardware as being part of someone's else ecosystem
it's a stretch to call it generic hardware, all of cheap cameras use similar hardware, but every few months there is a new version of chip which you need to adjust to. It's challenging to find an exact chip if you want to, because they get out of date faster than JS frameworks
