Yes the system will record when motion is identified. motion zones can be established so you don't get too many false positives, the only thing I have not been able to stop it doing is it tends to do a recording when our outside light automatically turns on as it is getting dark. The change in the light is recognized as movement, It captures the neighbors cat occasionally but that is okay. Other nice features are the ability to be notified to your phone on motion, on doorbell use, both or none. You can also set quiet times when you will not be notified so overnight it records but does not notify my phone, it still records though and I can review activities the next day.
