Outdoor Camera: Motion Type

I had a question regarding the outdoor camera's "Motion Type". I understand there are two options; (1) Person-only detection, (2) All Motion. My question is, does the camera still record all motion, even when "Person-only detection" is enabled, and just not alert/notify you? Or does the camera not record at all when "Person Only" mode type is enabled (except for when detecting humans). I couldn't tell for sure from the information listed in support and from the keywords used. I thought somewhere it did say it recorded anyway (although this wasn't an official response), and I remember seeing an official Simplisafe employee mentioning on the forums that the outdoor camera always records. I just wanted to clarify this. It sounded like it was possible the official support page was referring to alerts/notifications only, not specifically recording.
