I want to buy this camera and put it outside maybe 30ft away from my home. http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=6598199&csid=_61 I know it plugs into a regular wall socket. Does that mean I will have to plug it up inside my home with a extension cord, and run it all the way outside to the camera? Also what if it rains on the extension cord? Wouldn't that be a fire hazard.
