Wireless doorbell/intercom system
 

My brother wants a system that has a doorbell/communication device at his front door, then has a base station inside that also has a portable receiver that he can carry with him, like into the bathroom or the back yard. I checked on line with Radio Shack and was not impressed with their reviews and when I called for more help the person on the line said that they did not carry the intercom/doorbell units.
Anyone have any ideas?

May not be much help...but try this.
