Security & CCTV

🔒 What is Security & CCTV?

1. CCTV (Closed-Circuit Television)

CCTV is a video surveillance system that uses cameras to transmit signals to a specific set of monitors or recording devices. Unlike broadcast TV, the signal is not publicly distributed—hence “closed-circuit.”

🔹 Components of a CCTV System:

Cameras – Capture video footage (can be analog, digital, HD, or IP-based).
DVR/NVR – Digital Video Recorder (for analog) or Network Video Recorder (for IP cameras) stores and manages footage.
Monitors – Display live or recorded video.
Cables/Network – Transmit video signal (coaxial, Cat5e/Cat6, or fiber).
Power Supply – May include PoE (Power over Ethernet).

📷 Types of CCTV Cameras:

Dome Cameras – Discreet, ideal for indoor use.
Bullet Cameras – Longer range, visible deterrent.
PTZ Cameras – Pan-Tilt-Zoom; remote control for flexibility.
Infrared/Night Vision Cameras – For low-light or 24/7 surveillance.
Wireless/IP Cameras – Network-connected, often cloud-based.

2. Security Systems

These systems protect buildings from intrusions, theft, vandalism, or unauthorized access.

🔹 Common Features:

Door/Window Sensors – Detect entry.
Motion Detectors – Trigger alarms on unexpected movement.
Glass Break Sensors – Identify shattered glass.
Alarm Panels – Central hub for controlling and arming/disarming the system.
24/7 Monitoring – Alerts a monitoring service or police.
Smart Integration – Works with apps, lighting, or locks.

🔹 Add-ons:

Access Control – Card readers, keypads, biometric scanners.
Intercoms – For secure communication between entry points and personnel.
Remote Monitoring – View live feeds or control systems from mobile devices.
