I'm thinking of using this ftp service for my cameras however I currently only allowed motion recording on my free trial. Does the subscription plan include continuous recording? It does not specify.

Yes. 

CameraFTP offers the most flexible service plans. You can order an image recording or video recording plan; you can fully customize the recording parameters such as Resolution, Frame Rate and Retention Days. If you want to order a continuous recording plan, you just need to uncheck the "Motion Detection" checkbox in the Subscribe page.

 I understand now. The motion detection thing was a bit confusing as it seemed like a feature as opposed to a recording limitation. Would probably be clearer if it was a drop down menu for motion detection or continuous as opposed to a checkbox.

I was getting it confused with motion detection alerts. Thanks for the clarification.
