Thanks, I have several IRs at each corner of my house where I have cameras mounted on the soffit. Those IRs are as you stated, off to the side by foot. The ones I'm asking about today are for cameras mounted on two different trees along my driveway. The built-in IR is real bad about reflecting spiderwebs and raindrops etc. so I have made the decision to install separate IRs for these cameras as well. If my choice is above or below, what would you think?I usually mount auxiliary IRs off to one side on the same plane as the camera. All that's needed is a foot or so separation.
