Did not detect vehicle

So, Easter wknd here.

Multiple family members coming and Arlo camera picked up all vehicles except one...

Even when people started leaving at stagnant times. The one vehicle not picked up upon entry was also not picked up on camera on exit. Yet, all other vehicles were.

And no, it was not one vehicle after another but different entry and exit times.

Is this a concern?

How far away is the camera from the vehicles? The spec'd range for motion detection is only about 20 feet. While vehicles are usually detected from further away, the reliability will drop off as the distance increases. Also, the camera is more sensitive to side-to-side motion than it is to motion straight towards the camera. Plus it is more sensitive to motion at the bottom of the field of view than it is at the top.

So this might be due to where the missed vehicle parked, or possibly the size of the missed vehicle compared with the others.

I have seen some posts here from people who found that white vehicles weren't detected as reliably as other colors. This likely is because they aren't reflecting as much infrared - which is that triggers the passive infrared (PIR) sensor on the camera. So that is another possibility.
