I did something similar to what @Omgitstony suggested.
My first garage cam, I started with everything turned up, then started changing the sensitivity to fit that location. I was finding that light coming in through the garage window was triggering motion when I didn’t want it. I only wanted to know when one of the doors opened or a person came in, etc. Not when the light shifted through the window.
Then I realized another thing that would help was to use the detection zones. So everytime the sunlight set off my motion notification, I would go in and black that area out on the detection zone. Now it no longer caused me false notifications from that anymore. I still had enough of the garage door and the door to the house within the detection zone that anytime those opened or closed I got notifications. So it worked perfectly between detection zones and sensitivity levels.
Later I got cam plus as was able to have it alert me whenever it saw a person, which was pretty effective because whether getting into or out of the car, it would always see a person, so that worked too.
One other cool thing I did for a while before I had cam plus, is I had contact sensors and put one on my garage doors (the big one and the one to the house) and set up a rule to have it notify me and start a video every time one of those opened. The benefit of this is because if you don’t have cam plus, then the V3 will only be able to detect motion and upload something to the cloud once every 5 minutes. But with a contact sensor, there was no cooldown limit, so even if the camera was set off 1 minute ago by a lighting change, if either of those doors ever opened, it would still send me a notification and upload a cloud recording of that event.
There are lots of options, just play around and decide what is best for you.
