stabilizing brace

A camera stabilizer, or camera–stabilizing mount, is a device designed to hold a camera in a manner that prevents or compensates for unwanted camera movement, such as "camera shake".
For small hand-held cameras, a harness or contoured frame steadies the camera against the photographer's body. In some models, the camera mount is on an arm that protrudes in front of the photographer; beneath the camera is a handle grip. Another variation positions the camera atop a fulcrum braced against the photographer's chest or abdomen.
To compensate for camera instability caused by the movement of the operator's body, camera operator Garrett Brown invented the Steadicam, a body-mounted stabilization apparatus for motion picture cameras, which uses springs as shock absorbers.
In 1991, Martin Philip Stevens (born in England in 1963) invented a hand-held camera stabilizer for motion-picture and video cameras, called the Glidecam.
Some camera stabilization machines use gyroscopes to sense disruptive motion. The Artemis Trinity system from Arri combines a mechanical and electronic stabilization.Since approx. 2015, it is common to stabilize moving cameras with remote controlled camera heads. The camera and lens are mounted in a remote controlled camera holder which is then mounted on a moving dolly, such as rail systems, cable suspended dollys, cars or helicopters. For example the Newton stabilized remote head is broadly used to stabilize moving TV cameras at live broadcast of sports and events.

Although a tripod can hold a camera stably, stationary platforms are not regarded as camera stabilizers.
