And some quick reading the only place I could find 1200ft was for the traffic warning (speed traps, red light cameras, etc), I found the Escort 9500ix is rated a 1,200ft alert distance before arriving at a speed trap.

will give you an audible alert ("Caution — Speed Trap Ahead") 1,200 feet before you reach the location. Such an alert can easily mean the difference between complete rate-of-travel awareness and a momentarily lapse that results in a speeding ticket.
