Lightning Trigger: There is a great challenge in capturing lightning when it strikes. With this trigger things become much easier. Once the trigger detects a flash or burst of light it will activate the camera's shutter within 0.1ms. Motion Trigger: The unit's motion triggering modes uses a Passive Infrared (PIR)sensor. It detects movement of infrared (IR) sources, such as humans or animals, from up to 5 meters away, and smaller wildlife at a closer range. When the sensor detectsIR motion within its field of view (Horizontal: 94°, vertical: 82°), it will trigger your camera shutter. Sound Trigger: The sound trigger mode uses an insert microphone sensor. It will trigger the camera once the microphone detects any sound, such as the snapping of fingers, clapping hands or voice from human/ wildlife within approximately 2 metres. 0.1ms response time from lightning event to shutter release 5m PIR passive motion triggering capability when in Motion Mode; Set camera to manual focus and focus to infinity Power:IEC LR03 AAAx 2(not included) Compatibility: Nikon: D1, D1X, D1H, D100, D200,D2H, D2X, D3, D300, D3X, D3S, D4, D700, D800 1E, DCS 620, F100, F5, F6, N90,N90S,D3100, D5000, D5100, D7000,D90 Fuji : S3,S5
