Analog closed-circuit security cameras (CCTV) are a type of security camera that uses an analog video signal (CVBS / Composite Video Signal) to capture video surveillance images. Analogue security cameras can be connected to recorders and monitors using coaxial cables such as the RG59.
The image taken by the cameras and converted to CVBS are encoded by the recorder and recorded on internal hard drives.
Analog camera system parts can be written as:
As this operating system imposes a large processing load on the recorders, the expansion of the systems can reach up to 16 cameras *. Therefore, 16-split systems can be designed to install larger systems. As the number of cameras increases, so does the number of monitors. For this reason, matrix switching units capable of crossover are one of the biggest helpers of analog camera systems.
With a control keyboard, the user can draw any camera to the desired monitor via matrix switching, play back images written by the recorders to the hard disk, and change the direction and angle of the moving cameras.
Analog camera systems could not exceed 1000TV Line resolution. For higher resolution imaging;
* Although there are manufacturers producing larger systems, they did not show commercial success.
