What is a CCTV Camera?
CCTV stands for Closed-Circuit Television. A CCTV camera is a type of video camera that is used for security and surveillance. Unlike regular TV broadcasts, CCTV is a private system, and only certain people can view the footage.
These cameras are commonly used to monitor homes, shops, offices, roads, banks, and public areas. They help prevent crime, catch criminals, and make people feel safer.
Why CCTV Cameras Are Important
CCTV cameras are now an essential part of everyday life. Here are a few reasons why:
Safety and Security
CCTV cameras help keep homes, businesses, and public places safe. They act as a warning to criminals and help stop theft, break-ins, and vandalism.
Crime Investigation
If a crime happens, CCTV footage can be used as evidence. Police can use the video to identify and catch the suspects.
Remote Monitoring
Modern CCTV systems let users check the camera feed from a mobile phone or computer. You can watch your home or business from anywhere in the world.
Workplace Monitoring
Many companies use CCTV to watch employee behavior and make sure rules are followed. It also helps stop workplace theft and improves productivity.
Types of CCTV Cameras
There are many different types of CCTV cameras. The right one depends on what you need.
Dome Cameras
These are shaped like a dome and are often used indoors. They are small and not very noticeable, making them good for places like shops and homes.
Bullet Cameras

Infrared/Night Vision Cameras
These cameras can record in complete darkness. They use infrared LEDs to see in the dark and are great for areas with no light.
Wireless CCTV Cameras
These cameras use Wi-Fi instead of wires. They are easy to install and can be moved easily.
