Is there a way to install a stick up plugin outdoors?

Hi guys. I have 6 different cameras and 3 models, these stick up ones are giving me a headache. They bought the Stick Up Plugins. I see it's an AC/DC adaptor with a barrel tip. I don't understand how they will be installed outdoors. Can I just buy some $30 POE adaptors from Ring store, cat5e, and a POE switch? I ask because I see there's a Stick Up Camera POE version.
