Do You Fully Understand the Working Principle and Classification of PTZ?

What exactly is a Pan-Tilt for surveillance cameras? What types can PTZ be divided into according to usage and structure? How does a complete Pan Tilt Zoom system realize angle adjustment and limit control?

A Pan Tilt Zoom camera refers to a surveillance camera matched with PTZ, which can rotate horizontally and vertically to capture multi-angle images. The core part of the whole set is the Pan-Tilt, the supporting equipment used to fix and drive the camera. It is mainly split into fixed Pan-Tilt and motorized PTZ. Fixed style is used for areas with small monitoring range; after adjusting the angle, just lock the structure for stable monitoring.

Do you know how the motorized Pan Tilt Zoom operates? Two internal motors are responsible for left-right and up-down rotation respectively. Different operating voltages such as AC 24V, AC 220V and DC 12V will affect the working state of the entire PTZ. When the motor receives the control voltage, it drives gears and reduction boxes to rotate the device.

Does every Pan-Tilt have a limit protection structure? The answer is yes. Limit bolts and micro switches are installed inside, which will cut off the power and stop rotation when reaching the preset angle. In terms of usage environment, PTZ is also classified into indoor type and outdoor type. Outdoor Pan-Tilt has stronger load capacity, sealed rainproof structure and anti-freezing protection circuit to adapt to harsh weather.
