Sure, but there's no reason they couldn't be built into an enclosure that looks like other security cameras.

Alternatively, you just build a little box that has that extra stuff and plugs into a normal security camera, and you bury the box in the ground or put it inside a locked utility cabinet or something.

I mean, plenty of security cameras have WiFi capabilities. Adding bluetooth wouldn't be a very big lift. It definitely wouldn't be big enough to prevent a smaller form factor.
