Eliminates the need for a cable release. Allows the camera to be fired from an extended distance of up to 300 feet, unobstructed. Uses RF (radio frequency) signals, not line of sight like infrared.
Designed to fit specific cameras. Transmitter has a two-position switch, press lightly for prefocusing, and then continue pressing to release the shutter.
LED lights indicate prefocus and exosure. May be used on up-to 16 channels, user settable. Also allows the receiver to trigger the camera and thus be used as a "wired" cable release.
