Well we have conducted a T&E on the FACT Duty. It worked... The button hole camera is wide angle so everything 10 yards and in is detailed. However the further the range the smaller people/objects appear. The 500 lumen light is totally inadequate for police work at night. (I work straight night shifts) The beam of light the weapon light puts out disperses quickly, and really isn't worth a darn past 5 to 10 yards on a moonless night in the country. "Switch-ology" is weird with mushy activation buttons. Obviously it mounts to the pistol's accessory rail, but it just clamps and a cross screw/bolt holds the tension. The screw/bolt serves as the only recoil lug to keep the unit from sliding back and forth.
They also sent a long gun "prototype" model, which is the same light/camera with a cheapo tape switch added. Otherwise performance is exactly the same... poor. But the long gun model lacks the "instant-on" technology, which is half of their marketing ploy. Speaking of marketing, they really cherry pick the video they use to sell this thing.
I like the rechargeable battery setup, but otherwise everything else just feels cheap. They are NOT worth $500 a piece in my opinion.
Lastly, I can definitely believe that the company maybe shady. They are basically taking advantage of insecure admins and elected officials who believe that more video will prevent them from being tied up in civil court. Cops being sued is a cost of doing business, even if everything went according to law/policy. Its just the way society is now.
I like the holster activated camera idea, but having it mounted on a weapon isn't my favorite. I would rather see a glasses/head mounted camera instead. I'm sure people know, but the holster activation technology is available from other companies besides Viridian.
