Where are you looking to lock the camera from (what UI)? Since the only access is through the mobile app, if the mobile app is cutoff from the DCS-825L then how would you get back on (i.e. unlock)?
Maybe Iīm wrong , but if i register the camera to the Cloud, the you allways can access the camera remotly.
So if I would like to let my grandparents see my child, I give them my login to the cloud, then they can access this all the time thru the Dlink baby app (and maybe I donīt whant this)
Therefor I whould like to have, for example a checkbox "broadcast throu cloud".
