What type of signal is generated by a CCTV camera?

A CCTV camera typically generates a composite signal. This type of signal combines various data elements, including video information, into a single transmission. This makes it easier for standard television systems to receive and interpret the signal, as the composite format allows for the effective transmission of the video output through coaxial cables.

While digital signals are used in some modern systems, particularly those that integrate with IP technology for networked cameras, traditional analog CCTV systems rely on composite signals to carry video signals. Baseband, on the other hand, refers to a type of signal transmission that handles a single frequency, often used in local communications but not specifically representative of what a CCTV camera outputs directly. IP signal refers to signals transmitted over a network, which relates to newer digital camera systems but again isn't a characteristic of traditional CCTV cameras.

Understanding these distinctions is crucial for grasping how different systems work and how they communicate video data.
