I've decommissioned my remote observatory so have a couple of goodies needing a new home.
First up is a commercial grade internet power switching solution which includes in addition to the unit, four AU plug conversion sockets, each of which I would run into separate power boards to control different aspects of the observatory.
IP Power = $200 + Postage
Secondly is an IP Video server that allows control and viewing of up to four AV cameras. Used for an all sky camera + dome + security.
IP Video = $75 + postage
Needless to say, these require Wired Lan to work and internet to be web controllable.
