# Shutter release cable > A cable that fires the camera from an external device, such as a robot's control unit. Also known as: shutter cable, remote shutter release, wire shutter. Category: Hardware. A shutter release cable connects a camera's remote port to an external trigger so the shutter can be fired without touching the camera. In automated photography the trigger is the robot's controller, which fires the camera at exactly the right angle. ## How PhotoRobot uses it PhotoRobot control units fire cameras through their digital outputs; a dual output can, for example, pre-raise the mirror of an SLR with one signal and expose with the other. PhotoRobot prepares a shutter cable with a camera-specific connector, which is why it asks customers to confirm their camera model. Third-party cameras are supported when fired by cable from the control unit. ## See on photorobot.com - [Recommended cameras](https://www.photorobot.com/manuals/recommended-cameras) ## Related terms - [Control unit](https://www.photorobot.com/glossary/control-unit): The computer inside or beside every PhotoRobot that drives its motors, triggers cameras and connects it to the network. - [Fast Spin](https://www.photorobot.com/glossary/fast-spin): PhotoRobot capture mode that photographs during continuous turntable rotation instead of stopping at each angle. - [Tethered shooting](https://www.photorobot.com/glossary/tethered-shooting): Shooting with the camera connected to a computer, which controls settings and receives every image directly. - [Shutter lag](https://www.photorobot.com/glossary/shutter-lag): The delay between triggering a camera and the moment the image is actually exposed. ## Where this term appears on photorobot.com Mentioned on 13 pages.
