Beginner’s Guide to CCTV Camera Installation and Setup (Step by Step)

CCTV cameras are no longer a luxury—they are a necessity for offices, shops, and even homes. Installing them correctly ensures maximum security and reliable monitoring. This guide will walk you through the basics of CCTV installation step by step.

Why CCTV Cameras are Important

CCTV (Closed-Circuit Television) systems provide real-time monitoring and recording of activities. They act as a strong deterrent against theft, vandalism, and unauthorized access. For businesses, they are also useful for employee safety and compliance.

Types of CCTV Cameras

  • Dome Cameras: Compact and widely used indoors.
  • Bullet Cameras: Long and cylindrical, good for outdoor use.
  • IP Cameras: Internet-based cameras that can be accessed remotely.
  • PTZ Cameras: Pan-Tilt-Zoom cameras that can rotate and zoom for flexible coverage.

Basic Equipment Needed

  • CCTV Cameras (Dome/Bullet/IP)
  • DVR (Digital Video Recorder) or NVR (Network Video Recorder)
  • Power Supply Units
  • Hard Disk for Recording (at least 1 TB recommended)
  • Cabling (Coaxial for DVR or Cat6 for NVR/IP)
  • Monitor or TV for viewing

  1. Step 1: Choose the right locations—cover entry/exit points, hallways, and critical areas.
  2. Step 2: Mount the cameras using screws and brackets provided.
  3. Step 3: Connect cameras to DVR/NVR using coaxial or network cables.
  4. Step 4: Provide power supply to each camera.
