Strike Finder Pro - Camera Trigger w/ MC30 Cable for Nikon Cameras(Activated by Lightning and Laser includes Intervalometer) Lightning Activated Shutter Trigger was designed to capture lightning strikes either day or night. It uses microcontroller based technology along with an infrared sensor to capture the most stunning photographs with complete ease. The device mounts onto the camera hotshoe so you can walk away and let it do all of the hard work. Laser Trigger was designed to capture anything that breaks the beam from water droplets to people walking through it. Once the laser has been tripped, the device instantly sends a signal to the camera telling it to release the shutter. The shutter releases about 45-60ms later, depending on the camera. Intervalometer allows you to do time lapse photography. The device contains a small knob that that adjusts the duration of the time lapse from 1s to 10 min. Once set, the device sends a signal to the camera to release the shutter at the specified duration.
