# Pan Tilt Unit Overview
## What is a Pan Tilt Unit?
A pan tilt unit (PTU) is a mechanical device that provides rotation in two axes: horizontal (pan) and vertical (tilt). These units are commonly used in various applications where precise control of camera or sensor orientation is required.
## Key Components of a Pan Tilt Unit
A typical pan tilt unit consists of several essential components:
– Base: The stationary part that provides stability
– Pan mechanism: Enables horizontal rotation
– Tilt mechanism: Enables vertical rotation
– Motors: Provide the movement (often servo or stepper motors)
– Control system: Manages the unit’s movements
## Common Applications
Pan tilt units find applications in numerous fields:
– Surveillance systems
– Robotics
– Photography and videography
– Astronomy
– Industrial inspection
– Military and defense systems
## Types of Pan Tilt Units
There are several types of PTUs available in the market:
