Total Subjects:	2

1: Basic Electronics & Field Tools

Before touching a camera, you must understand how power and signals work to avoid damaging expensive equipment.

Principles of Electricity: Understanding AC/DC current, voltage, and power requirements for different cameras.

Electronic Components: Testing resistors, capacitors, and diodes using a Multimeter.

Cabling & Connectors: Hands-on practice with Coaxial (RG59/RG6) cables, Cat5/Cat6 (Ethernet), and crimping BNC and RJ45 connectors.

Technician Tools: Mastery of drills, wire strippers, crimping tools, and signal testers.

 2: CCTV Hardware & Lens Technology

This block covers the "eyes" and "ears" of the surveillance system.

Camera Types: Learning when to use Dome (indoor), Bullet (outdoor/long-range), PTZ (Pan-Tilt-Zoom), and C-Mount cameras.

Lens Theory: Understanding focal length, aperture, and Field of View (FoV) to ensure the right area is captured.

Image Sensors: The difference between CCD and CMOS sensors, and understanding "TV Lines" (TVL) vs. Megapixels.

Night Vision & Illumination: Setting up Infrared (IR) LEDs and understanding lux levels for low-light recording.

 3: Recording, Storage & Networking

This is where the "video" becomes "data." You will learn how to manage and protect recorded footage.

DVR vs. NVR:

DVR (Digital Video Recorder): Used for analog cameras.

NVR (Network Video Recorder): Used for modern IP (Internet Protocol) cameras.

Storage Management: Calculating Hard Disk Drive (HDD) space based on resolution, frame rate, and "Retention Period" (how many days you need to keep footage).

Video Compression: Understanding standards like H.264 and H.265 to save disk space without losing quality.

Remote Monitoring: Configuring the system so the client can view live footage on their Smartphone or Laptop from anywhere in the world.

 4: Site Survey, Maintenance & Legalities

The final phase focuses on the professional "business" side of being a technician.

Site Survey: Learning how to walk through a building to identify "blind spots" and optimal camera placement.

Troubleshooting: Diagnosing common issues like "Video Loss," "Ghosting" (double images), or network lag.

Legal & Ethical Standards: Understanding privacy laws (where you cannot point a camera) and data protection.

Soft Skills: Customer interaction, preparing a Bill of Materials (BoM), and safety protocols for working on ladders or high structures.
