What type of signal does a CCTV camera generate?
Underpinning a CCTV camera is a CCD sensor (charge-coupled device). The CCD converts light into an electrical signal and then signal processing converts this electrical signal into a video signal that can be recorded or displayed on the screen.
Is CCTV analog or digital?
Analog refers to CCTV cameras which us an analog video signal that is transmitted over coaxial cable back to a video recorder or monitor. So, the modern CCTV surveillance system (still sometimes called analog ) is actually analog on the camera and cable side, but digital on the recorder side.
What format are security cameras?

Why is digital video better than analog?
A copy of a digital recording is as clear as the original, no matter how many generations of copies have been made, because the ones and zeroes of each copy are identical. This capacity to make an infinite number of copies with no degradation is alone enough to justify a move from analog to digital recording methods.
Is digital or analog better?
Digital recordings can have a greater signal-to-noise ratio depending on the bit depth of the recording. The smooth analog signal matches the recorded sound wave better than the steps of a digital recording.
