A Closed-Circuit Television (CCTV) camera is a security device used for monitoring, recording, and transmitting video footage within a private network. Unlike broadcast television, CCTV footage is restricted to authorized users, making it a crucial tool for security, crime prevention, and surveillance.

How Does a CCTV Camera Work?
Lens Captures Footage – The camera lens gathers light and focuses it on the image sensor.

Image Sensor Converts Light – CMOS or CCD sensors process the light into digital signals.

Video Processing & Transmission – The signals are sent to a monitor, recording device (DVR/NVR), or cloud storage.

Storage & Monitoring – The footage is saved for real-time or later viewing.

Types of CCTV Cameras
1. Dome Cameras
✔ Used for indoor and outdoor surveillance.
✔ 360-degree rotation provides a wider field of view.

2. Bullet Cameras
✔ Long-range, cylindrical design for outdoor security.
✔ Ideal for parking lots, highways, and perimeters.
