Suggestions for motion sensor that detects people (avoiding false detection because of wind)

Similar to comment above regarding Blue Iris, here is another option Iā€™ve set up using tinyCAM (runs on Android) which can report motion, person, vehicle, pet and faceā€¦

Another thing to consider is whether you can apply a ā€˜maskā€™ to the scene so that motion sensing only occurs within specified areas of the camera view, to avoid problematic areas. This is something many camera apps support. tinyCAM supports this too of course, as Iā€™m sure BI will too.
