1) I think yes, generally speaking, occupancy sensors "senses" occupancy instead of translated movement. They are more "sensible".
X10 wireless PIR's, for example, offers ON status when a movement is detected and OFF status when a movement is not detected for a selectable amount of time.
Security wireless PIR's, like "Visionic", for example, have a battery saver system and, for many reasons, are not suitable for occupany sensors.
2) Yes, i use x10 wireless PIR's (suitables as occupancy sensors), but you can use any type of wired PIR (in this case, you need to manually program a retarded response that switch off your light, because PIR's generally doesn't send OFF status) .
3) I don't know, sorry.
