I gather it will work but does cause problems if all the legs are long, I
cannot remember the reason but it is in the data book. Dallas recommend
using switches to isolate legs to improve propagation and reduce the load
on
the network, the I idea is you switch on a leg then access the device on
the
leg, when you have finished with a device you instruct the switch to open
again cutting of the leg, from memory its a DS2405.

In a home vision set-up you are unlikely to be able to use this approach.
