Thunder, I spoke with Mr. Louh at FLIR. In answer to your last question, the answer is yes they can be adjusted to do about anything that you want them to do including scaring a customer into uneeded repairs.
I figured that they would be pricey and they are. They recommended a B1 model (B is for building) that sells for a mere $10K, If you want something a little more versitile the E4 is a steal at $20K.
I think that I would ensure that there is a market prior to spending that kind of money.
