I installed it as well (DS2047G2-LU), i set up the light option into intruder smart detection, i set 5 sec into the linkage methode., i walked nearby the camera, got notified by the app, light went on
, but it stayed on 10 sec and after 25 min when returning from a walk, it still was burning.....................
On my NVR the same, no option yet for motion or smart event to set the light on.
Did your light went out using motion detection after your 60s?
it just being explained, i tested the wrong smart event, which seems to bugged ;-)
