"doorbell camera" but not "camera"?

[HactarCE]

It came up on the Discord that it's strange there's a root ȚMY for "doorbell camera" but none for "camera" (you're supposed to derive it from MZ "remember / memory"). I (and HamNcheese95 on the Discord) propose that ȚMY be repurposed to mean "camera," with "doorbell camera" expressed using an incorporated root or similar. (I'm not familiar enough with Ithkuil IV to know exactly how this would work; please correct me if it seems impractical.)

Alternatively, add a affix to mean "device for creating/capturing/recording," and then we can use it to derive "photo camera" and "video camera" from Ż+CTE, along with "microphone" etc. from other roots. (When designing this affix, also consider similar devices, such as devices that livestream but do not save the data, or that process it in realtime but are not themselves recording it.) Either way, "doorbell camera" seems like overkill.

Doesnt seem to be a root for just “doorbell” either.
