From what I can see, this is not true.
The Exacq rep in our area is now pitching Exacq products AND American Dynamic cameras to Kantech customers and vice-versa.
One of my dealer friends had a visit from the Exacq guy who was accompanied by the Kantech rep (they are not a Kantech dealer nor did they show any inclination towards Kantech) - the 2 guys were visiting each other's customers together.
They are sharing customer information- this could not be any clearer
