Analog cameras record images and then send the signal over a coaxial cable to a DVR (Digital Video Recorder). The DVR converts the video from analog to digital signals, compresses the file, and stores it on a hard drive. Then, they can receive and send data over a computer network rather than going through a DVR first.
Analog Coaxial DVR RecordersIn a DVR system, the analog cameras stream an analog signal to the recorder, which then processes the images. The advantage of this system is the reduced complexity required of the camera when compared to an NVR system. Cable – Coaxial BNC Cable. The camera connects to the DVR recorder via a coaxial BNC cable.
Analog Coaxial CamerasAn analog camera is a traditional camera used in CCTV systems. It sends video over cable to VCRs or DVRs. There was no such thing as an HD analog or IP (Internet Protocol) camera. An analog security camera is a low-resolution camera by today's standards that used a coaxial cable to connect the camera to the digital video recorder (DVR) or to a video monitor.
