If you need to fire your camera from a distance you’ll need a remote trigger. Unlike a cable release, remote triggers give you the opportunity to move much further away as they use infrared beams or radio frequencies to communicate with your camera. The ranges of remote triggers differ from trigger to trigger but there are versions that can fire a camera from a massive 80m away. Be sure to check the distance and range of your trigger before parting with your cash.
Where some remote triggers plug straight into the manufactur’s release port, others will fit on top of the camera’s hot-shoe and use a small lead to plug into the release port. Most remote triggers have been designed to be used in front and behind the camera. They are also a great way of combating camera shake when you fire the shutter.
