PTZ cameras, or Pan-Tilt-Zoom cameras, are versatile surveillance devices that can move horizontally (pan), vertically (tilt), and zoom in on subjects. This functionality allows them to cover large areas and focus on specific details, making them ideal for monitoring public spaces, businesses, and homes. These cameras can be controlled remotely, often through software or a mobile app, enabling users to adjust the camera's position and zoom level in real-time. Many PTZ cameras also come equipped with features like night vision and motion detection, enhancing their effectiveness in various lighting conditions and situations.
