The Shutter-Beam IR Beam
and Sound triggering device allows you to use sound and light
triggering to capture high speed photographs of just about anything
that moves or can be made to move.
In order to hook up to a camera you will need a Shutter
Release Cord. An External Power
Adapter (EPA) can be used to
plug the Shutter-Beam into a wall rather than run on batteries
(included).
