only on (some) hikvision colorvu gen2 with newest firmware possible
if you are using
blueiris you might be able add an motion trigger action and turn it on with api
i think they dont add it because its somehow useless. if you are near complete darkness it should be impossible for software to detect motion... also maybe some problems with exposure settings..
near trustful solution in my opinion to add a pir sensor to the alarm input and link it somehow. but then you can also add a simple motion floodlight
