Winds affect the camera's motion detections?

ant — Fri, 30 Sep 2016 00:26:25 GMT

Hello.

Today is a clear sunny day, but a little windy. The outdoor cameras are picking up movements. Is it because of trees' branches and leaves moving around? If so, then I thought the cameras sense motions based on heat. I don't want to lower the sensitivities to miss other things tiny animals, people, etc.

Thank you in advance. 🙂

Also, today is warm. It is about 72F degrees right now if that matters.

snip... Is it because of trees' branches and leaves moving around? If so, then I thought the cameras sense motions based on heat. I don't want to lower the sensitivities to miss other things tiny animals, people, etc.
The IR sensor does not pick up heat... it picks up IR or reflected IR off of objects. So if the sun is shining and reflecting off of the objects moving in the wind, it can set off the motion detect.

There are many threads on here re adjusting for motion, put "motion" in the info bar above "search for answers"

So, pointing a mounted camera at house's sides with reflective windows from a tree is a bad idea? No sun shining on them though. I also see some branches and leaves on the camera's corners. Maybe it would help to cut them off. FYI, this is in a rural area with lots of trees and plants.

Just lower the sensitivity.....

OK. I hope it won't miss anything important. We are going to try to trim the moving branches and leaves that we can see in the camera's view corners (1/fir)st.
