Closed-circuit television (CCTV) cameras are a popular security solution for homes, businesses, and public spaces. They work by capturing video footage and sending it to a monitor or recording device for viewing. This tutorial will explain the basics of how CCTV cameras work and their different components.
Introduction
CCTV cameras are designed to capture video footage of a specific area and send it to a monitor or recording device.
