my two cents on the range ops. the pic quality on them is pretty poor. same with the mid range one. and the one range ops i bought takes about 70% of my daylight pics as night pics. not too happy about that. good in that it does indeed get pics of what shows up, not a bunch of false triggers. anyway the higher end one, the spec ops, is supposed to be better, and i just found them for $140 each so i bought 3, but wont be putting them up until snow melts.
