It can do both. Mine is set to record all the time (normal/Parking/event modes) but if to stops record due to no inactivity (no motion, movement or event) then it will wake up and start recording if it senses motion/movement/event.

In a parking lot there's always cars coming and going, people walking by and other various things "moving" so the motion sensor wouldn't likely let your camera go into standby mode.
