What type of camera is most commonly used in CCTV systems?

Dome cameras are most commonly used in CCTV systems due to their versatile design and functionality. The dome shape allows for better aesthetic integration into various environments, making them less obtrusive and more discreet than other types of cameras. Additionally, dome cameras often come with a built-in infrared capability for night vision, making them effective in low-light conditions.

Their ability to diffuse focus makes it difficult for individuals to determine the direction in which the camera is pointing, which can serve as a deterrent to potential intruders. Because of these combined advantages—protection from tampering, enhanced night vision, and a low profile—dome cameras are widely utilized in both indoor and outdoor surveillance applications.
