Today’s cameras are more advanced, more affordable, and easier to install. Features like human detection, color night vision, AI analytics, cloud backup, and remote monitoring have made CCTV systems intelligent and proactive—not just passive recording devices.
This guide covers everything you need to know before choosing, buying, installing, or maintaining a CCTV system. Whether you’re securing a home, shop, office, warehouse, apartment, school, or factory, this pillar article gives you all the information needed to make the right decision.
Understanding How CCTV Systems Work
A modern CCTV system includes:
