Some things that should be considered.
The cameras trigger using the infrared detector (<25ft) within the camera not by the view that is seen, so wanted motion needs to be across the field of view. Eg. If a camera faces down a driveway it will not always trigger until someone gets out.
There is a 10sec reset time between motion events. Using record until motion stops is good for most needs but reliable viewing of an events should be using fixed record length.
Motion sensitivity adjustments are available for each camera rule within in each mode that can customise your requirements but camera placement should be optimised first.
