How good is the Motion Detection?

How far away does the motion detection detect objects moving? I believe these cameras can see 30 feet away. Do these cameras have good motion detection?

Motion detection is based on pixel to pixel change over time, so distance is not really a factor. It’s not like the sensor used in an alarm system or motion activated security light. As long as the moving object is large enough relative to the frame and there is enough contrast, it will pick it up.

Thank you, Rick. This answer helps me out.

There isn’t any motion detection at all.

It is all done by pixel comparisons between frames.

So, light difference, wind blowing things, and so on will trigger the alerts.
