Sounds good, where did you get it ?
I am afraid my OH is the gizmo person in our house. But we basically bought an indoor camera (with IR capability) with an IP over mains transmitter for the distance from the goathouse to our house, plus some extra cable from the extension connection for the goathouse (in the garage) to the router in the house because of interference.
Bit if you have clear line of sight between your house and the goathouse you can get easy transmission to either a computer screen or a TV (which we haven't got).
There are a few "ready made" systems available, usually sold under "lambing cameras", but our combination worked out cheaper.
Hope your girls get on with it! (I am sure they will - weather forecast is a bit wild... snow down your way?)
The whole caboodle came from Amazon.
