Hi, Is there a way with Motion to count all occurrences detected in pre-made video? I have 30min video that is mostly black and only one orange led is blinking in 10sec pattern with 2 sec pause trying to tell me the issue with hardware (blinking service code). I know that motion is able to trigger action based on motion detection, but is able to like show me number of how many blinks was issued durring 10sec session? Thanks for any reply
