FG, nice try...
man are you a hack at the bashing stuff. A little digging on the link you provided says goes to 250 feet and costs $15,000. yes folks thats $15,000. (just a little more money? who are you kidding)
SEVU could set up security in walmart's parking lot for less than that. LOLOLOLOLOLOLOLOLOLOLOL. Oh, and I believe they have.
Thanks, you just made me feel better about SEVU.
JMHO
