How do analog cameras work?

Published in Analog Cameras 1 min read

Analog cameras function by capturing video material and converting it into analog signals, which are then transmitted to recording equipment. This is achieved by sending footage in analog format via coaxial lines to recording equipment, such as Digital Video Recorders (DVRs).

Here's a breakdown of the process:

  • Image Capture: The camera captures the visual scene.
  • Analog Conversion: The captured image is converted into an analog electrical signal. This signal represents the variations in brightness and color within the image.
  • Transmission: The analog signal is then transmitted through a coaxial cable to a recording device, typically a DVR or other analog recording system.
  • Recording: The recording device stores the incoming analog signal.

This entire process leverages technology as old as electricity, providing a smooth transmission of video data in analog format.
