The ProMaster Multi-Function IR Timer Remote triggers your shutter wirelessly or wired using an OPTIONAL ProMaster Camera Release Cable. It's also equipped to handle a long list of timer functions: self-timer, interval timer, long exposure timer, as well as controlling the number of continuous shutter releases. It works with almost any camera that has infrared capability. In the infrared mode, the remote will trigger your camera up to 30' away depending on the lighting conditions and line of sight to your camera's infrared receiver.
