You would need to mount it in a way that someone couldn't just come along and pick it up and go. Any mounting solution that requires internal access to undo would be a further deterrent.

Cameras would help too, and if you have either a very strong router (like a Ruckus), or cellular service, you could even potentially get notifications from the camera, prompting you to walk back because someone is attempting to unmount your stuff. Even just talking through one of those doorbell cameras will probably make them scurry off.

Even if you just slapped a simple chain bike lock on everything before you walked away that's probably going to stop most if not all attempts at stealing your stuff.
