Notifications are irrelevent. That's just what you set it to tell you. If you set it to trigger recording on motion, it will trigger recording on motion. If you're recording to an SD card which has limited memory, then it will over write anything already there. So that burglar it records when they trip the trip wires at 9.30am, will get over written by the midge swarm mid morning or the swaying bush, leaving you with video of midges or the bush and not the burglar. Also, I hope you bought an expensive endurance memory version, because most ordinary SD cards do not like continuos or intense writing. It's better than nothing, but recording to internal SD is not very reliable either.
