Node AP's

I looking for clarification about the following question

How can I connect non-mesh clients to my batman-adv network ? Does this mean that for an existing batman node to allow non-mesh clients to join (I.E. cell phone, wifi camera, etc..), then 2 interfaces are required?

For example, if I have a pi-zero W in a wooded area, and I want a camera to connect to it, then do I need to add an additional usb network adapter to the Pi. One Interface for the Bat0 Mesh and One interface an an entry point for non-mesh clients.

any information is greatly appreciated.

Thanks Zach
