IP cameras on ring topology, not star

[Pat Coghlan <info@xxxxxxxxxx>]

I'm looking for information on equipment that can/should be used to
install IP video cameras on poles around a perimeter (1-2 km, or more).

Token-ring routers typically require all drops to be plugged into a
panel (operates in token ring fashion, but physically is a star), which
is not practical with 100 cameras running around a ring, feeding traffic
back to recorders.

The equipment needs to be economical (hub on each pole).

Any suggestions or real-world examples out there?

Thanks.
