CCTV cameras are becoming more common day by day as the IT sector is experiencing an explosion and the related technology is becoming more sophisticated. There are many types of surveillance cameras such as hidden cameras, dome cameras, smoke detectors, and "smart" cameras equipped with motion detectors.
CCTV cameras can also be classified according to the technology used in them. A CCTV camera is a camera that has a fully closed circuit and all elements are interconnected. In contrast, high-end digital cameras are cameras that are not connected to a circuit, but can be installed anywhere in the world.

Digital video recorders do not require VCRs and other recording devices to record or record on-site activities. The software automatically records unusual activities at odd times of day.
CCTV cameras are used on school and school buses to monitor student activity. There are also hidden cameras on the market that are usually hidden in watches, smoke alarms, and stuffed animals like bears. These cameras can also be distinguished according to their efficiency.
The dome camera rotates 360 degrees to take pictures anywhere on the site. Infrared surveillance cameras are used by government agencies such as SWAT to track down suspects at night.
Security agencies and detective agencies use these cameras to monitor people at the request of their clients. Setting up cameras and recording public activities is legal and there is a lot of discussion on the subject.
