Without some serious software, out door motion detection is subject to a lot of false alarms. If sun and shadow is in view, ever time the clouds come by there's a good chance. Flipping in to (usually automatic) IR mode vs visible light may cause an alert if they are not somehow synchronized. At night i have the occasional large bug (moth for example) fly near the lens. I had some jet skis parked in my driveway which had fairly tight covers on them, but just wind blowing against the cover kept triggering motion. Waving leaves can be masked off but their shadows are more of a problem.
Not saying it's not possible, just that it can be a serious challenge; when I was looking for NVR software some tools had much more serious analytical tools than just motion, e.g. line crossing or tracking, or recognizing the difference in people and non-people. But they are more rare than just "motion".
Now indoor motion is usually easier because you can control all that stuff.
