AmericanDJ VFWR2 Wireless Fog Machine Remote

The ADJ VFWR2 is a wireless remote for the ADJ VF1300 and VF1600 fog machines, putting the fog trigger in the operator's hand rather than at the machine.

Fog machines end up on the floor at the edge of a stage or behind a riser, which is precisely where nobody can reach them on cue. A wireless trigger is what makes the effect usable in a show. ADJ catalogues it under Fluid, Timer and Accessories as part number VFWR2.
