I wanted to get everyones thoughts on how to extend the power cable to an outlet if an outlet is no where close to where the customer wanted the device. I'm talking about ceiling hung CCTV monitors, cameras, audio equipment, tvs, anything you wanna share...

Personally I've seen a 12" b/w monitor power cable extended 20 feet with 16/4 speaker cable in the crawl space above a false ceiling. I thought this was kinda odd and not sure about the safety of it so I wanted to see what everyones thoughts are...
