Nursery Video and Paging

As most of you know we have had a TV setup in the nursery for some time now. The parents using it have asked to update it so that there is a clearer picture and better sound. One of the changes I am trying is different camera positions in the gym. It also looks like we have to abandon the wireless feed as there is too much interferance with the signal (doesn't like going through walls). We have also purchased a wireless paging system for paging parents to the nursery. All of this is going to be installed onto a cart so that there is only one plug to attach each Sunday. To help with this we need to do some high level wireing with the beloved scaffold, if anyone can help on Sat. Oct. 14 from 9 to 11 please let me know.
