Always TEST all proposed locations using a temporary mount prior to permanent mountings. Test rig: 8'x2x4, 5 gal bucket, and rocks for ballast. Test for a minimum of 24 hrs.
If you aren't careful, you will get IR reflected back into the dome of the cam and cause issue's at night from the slopped part of the soffit.
You want a PTZ to be mounted on a level horizontal surface, or it won't track correctly when you pan the lens.
That also looks to be too high. Don't mount cams over 7-8' for best chance of face ID's.
I would get some thin aluminum stock, and fashion a bracket so that you can mount the cam on or near the bottom of the gutter.
You are almost always better off with more fixed cameras, over a PTZ. The ptz has a high likelihood of looking in the wrong direction when something happens.
Also, keep in mind the IR on that cam isn't very strong, so you will probably want additional white light or a separate
IR illuminator to light up the yard.
Courtesy of Andy @ Empire Technology @EMPIRETECANDY we have a new Mini PTZ to check out. This is similar to the one that @tangent reviewed, except this one includes zoom and IR illumination, his model does not. You can see his review here of the SD12200T-GN: Review: Dahua Starlight Mini PT Dome...
