CCTV

CCTV stands for Closed-Circuit Television. It is a system used for surveillance and monitoring by capturing and transmitting video footage to a limited set of monitors.

📹 What is CCTV Used For?

• Security and surveillance (homes, businesses, public places)
• Crime prevention and investigation
• Traffic monitoring
• Industrial processes monitoring
• Access control in buildings

🔧 How CCTV Works:

1. Cameras capture video footage.
2. The footage is sent to a monitor or recording device.
3. Only specific people can view it — it’s not broadcast to the public (hence “closed-circuit”).
4. DVR/NVR systems (Digital or Network Video Recorders) can store the video for later review.

🛠️ Types of CCTV Cameras:

• Dome Camera (used indoors, discreet)
• Bullet Camera (long-range, outdoors)
• PTZ Camera (Pan, Tilt, Zoom — remote-controlled)
• IP Camera (connects via internet)
• Wireless CCTV (no cables, uses Wi-Fi)

📍 Common Places You See CCTV:

• Banks
• Stores and malls
• Airports and train stations
• Streets and intersections
• Homes (smart home security systems)

CCTV helps deter criminal activity and provides evidence when incidents occur.
