canon 100d half shutter video

[ccgokgul]

i am setting camera trap in the field , so i am using the passive infrared sensor to wake my sleeping camera ..i loaded ml to capture video for same aim...before loading ml my sl1 takes photo when you press movie button in video mode , after loading sl1 and setting the camera recording video by pressing the shutter , the motion activated (from shutter released input) camera cant decide to shoot video or photo , generally choses to take photo and i cant take video , many thanks...
