What types of cameras are commonly used in security surveillance systems?

Commonly used cameras in security surveillance systems include dome cameras, bullet cameras, and PTZ cameras. Dome cameras are discreet and provide a 360-degree view, making them suitable for indoor and outdoor monitoring. Bullet cameras are long and cylindrical, ideal for long-range surveillance in outdoor areas. They are weatherproof and have infrared capabilities for night vision. PTZ (Pan-Tilt-Zoom) cameras offer the ability to pan, tilt, and zoom to capture a wider area and focus on specific points of interest. They can be controlled remotely for versatile monitoring. These cameras are often equipped with high-resolution capabilities, infrared sensors, and built-in storage options. The choice of camera type depends on the surveillance needs, such as the area to be monitored, lighting conditions, and specific requirements of the security surveillance system.
