Trying to understand how motion detection really works so I can record ALL motion around car in front of house

Background: I had my car wheels stolen just in front of our house one night a few weeks ago. Goal 1: prevent reoccurrence of theft, or at least get a recording of thieves in the act. Constraint: car is parked aligned with camera within, but very close to, the 30 ft mark. Goal 2 (unrelated to goal 1): detect all people walking on walkway which goes roughly from one end of car to house. Constraint: car, door and camera are all aligned. Problem: recording of people around car or on walkway happens only very sporadically. I initially purchased the cheapest Ring Video Doorbell, and as it did not work well, I gave the Battery Doorbell Pro a try, but it does not help. Note: in parallel, I purchased a couple of Blink Outdoor 4 at a fraction of the price of the Rings and they do work. So, I think my goal is reasonable. I also purchased a Stick Up Cam Battery for troubleshooting purpose. They have a small blue LED that turns on when they wake up, I assume based on infrared sensor input. I can see that them waking up does not necessarily mean that a recording will be made. I therefore assume that they do a bit of image analysis once they wake up and go back to sleep if the image analysis does not see anything of interest. By extension I assume that, for the Battery Doorbell Pro, the radar input is also taken into account. If those assumptions are correct, the problem is that I am not sure what to do to skip the (faulty) image analysis so that recordings are made whenever the infrared sensors detect movement. Also, the radar does not work well when I walk around my car, and I do not know what to expect when the radar cannot confirm that detected movement is within the specified zone. What should I do? Thanks! E.g. should I disable Bird's Eye Zone? Will I still be able to record the 3D paths if I do so? What does "motion sensitivity" refer to exactly? Image analysis? If so, is there a way to completely skip image analysis?
