Yes, it can be set to only capture motion. Motion can easily be turned off. It can also be set to stop recording when the memory card is full, or to overwrite. And can be set to record in full HD or to record the “Sub Stream” (lower resolution).

What are the dimensions of this thing? The Tech Spec page on the Amcrest website has a spot for dimensions but it’s blank.
