There are mainly three types of CCTV cameras based on technology.
Analog Camera: The analog camera was used in earlier times when the CCTV market was not as digital as it is today. Video and image quality on analog cameras is not as good as it is today. The image quality or image resolution that can be captured by the camera on these types of cameras is measured in terms of TVL, such as 420 TVL, 480, 650 or 7oo TVL i.e. more the camera has TVL, the better its quality. . of picture. They will be .
In an analog camera setup, each camera is directly connected to the DVR via coaxial cable, where the camera captures video and then sends that captured video or image to the DVR via the coaxial cable. Then the DVR processes the received videos from different cameras and finally we get a finished video, but the clarity of this video is much clearer than it is today.
Analog HD Camera: Analog HD camera is also a member of analog camera family, but its video quality is much better than ordinary analog camera i.e. it records the video in high definition. The camera capacity of an analog HD camera is measured in megapixels, such as 1MP, 2MP, 4MP, etc. Simply put, the more megapixels the camera has, the better the video quality will be.
