The Bower RCWUNI Universal Wireless Shutter Release Set is an extended range infrared wireless system designed for professional and advanced amateur users of Canon, Minolta, Nikon, Pentax, Samsung, and Sony cameras. The set consists of the shutter release transmitter, plus connectors for a wide range of cameras. If your camera supports an infrared sensor then the RCWUNI can be used wirelessly, otherwise, one of six included cables will allow this system to work as a wired remote.
The remote system is ideal for taking pictures of subjects that are difficult to approach, or to minimize vibration for close-ups and time exposures. The transmitter fires the camera from a maximum distance of 150' (45.7 m). Sixteen transmission channels are available to prevent interference between other cameras using wireless remotes.
