A cold shoe is a mounting point on the top of a camera used to attach an accessory that doesn't require an electrical connection. Cold shoes are used with off-camera flash units, mounted on stands, and connected to the camera by cable or triggered wirelessly. Accessories that do not connect electrically to the camera can be inserted into hot shoes, without using the contacts. For instance, a stereo microphone or electronic viewfinder can be used in the Olympus XZ-1 camera's hot shoe. FotoSpot geotagging satellite positioning units utilize the accessory shoe for mounting to the camera.
