There aren’t any cameras which connect directly to the smartthings hub.
Most use a cloud to cloud connection, in which case the camera has to be able to access Wi-Fi.
Most of the battery operated cameras use a plug-in base for their Wi-Fi connection because otherwise they will use up the battery too quickly.
The only exception I know are some of the battery operated ring models. They don’t need a base station. But they are quite expensive and The batteries need to be recharged frequently unless you get a solar charger, which adds yet another cost. And only some of the models work with smartthings.

But in general most cameras need a Plugged in base station to support the power demands of Wi-Fi, and Wi-Fi is how they will integrate with smartthings.
