Connect all speed domes to host in daisy chain pattern as possible as you can
Star type configuration should be avoided to keep system away from
instability.
Each speed dome must have its unique ID so communication data can be
delivered to the correct target device.
Impedance-match setup is also required to keep RS485 communication
quality.
Make wire distribution
Connect the other end of the cable to a phone box with extension outlet of two.
Installer must pay attention to the pins of the extension box to ensure the
connection is correct.

above. You may continue extending the quantity of camera
to its maximum number of 128 per network, if the control
device has the capability of addressing that many ID..
