Faketv is a burglar deterrent that recreates the light of a real hdtv television. So from outside, it looks like someone is home watching tv. Most burglars do not target occupied houses. Why risk prison? So when a prowler sees that flickering glow that means someone is home watching tv, he knows to move on to an easier target. So, facet makes a break-in less likely. The ftv-7 simulates the light output of a 27" tv, just like our ftv-10. It is a little smaller in size than the ftv-10. Also, the ftv-7 has only one timer setting: Dusk +5 hours. The ftv-10 and ftv-11 have two: Dusk +4 hours, and dusk +7 hours. Faketv's built-in computer controls 7 super-bright leds that fill a room with light. It accurately simulates scene changes, fades, and on-screen motion, in thousand of possible shades of color, just like real tv. A built-in light sensor turns facet on at dusk, and it can be set to turn off after four or seven hours. The dynamic light from facet conveys the impression of "alive" in a way that a light on a timer cannot. Consumes just the power of a night light. AC adapter included.
