Whether you manage a busy retail shop in K.B. Royal Complex, operate a office in Motera, or want to secure your family home in Chandkheda, installing a reliable CCTV camera system is the single most effective deterrent against theft, unauthorized intrusion, and property disputes.
However, entering the CCTV market can be overwhelming with technical jargon like DVR, NVR, PoE, 2MP vs 5MP, and ColorVu. At Radhe Computer, our security lead Jitendra Arora has installed over 300+ CCTV camera channels across Ahmedabad. Here is your practical 2026 CCTV installation guide.
1. Dome vs Bullet Cameras: What's the Difference?
Selecting the right camera shape depends on where it will be mounted:
- Dome Cameras: Compact, spherical cameras designed for indoor ceilings (offices, shop counters, living rooms). Their rounded housing makes it difficult for onlookers to see which direction the lens is pointed.
- Bullet Cameras: Cylindrical, weatherproof cameras designed for outdoor walls, gates, parking lots, and building perimeters. Their prominent shape acts as a strong visual warning.
2. HD Analog vs IP Cameras: Which Technology Do You Need?
HD Analog Systems (DVR Based)
HD Analog cameras (e.g. 2MP or 5MP CP Plus / Hikvision) connect to a Digital Video Recorder (DVR) via coaxial cables. They offer fantastic 1080p video clarity, extreme reliability, and are the most cost-effective choice for small retail shops and apartments.
IP Cameras (NVR Based)
IP Cameras record video digitally and transmit data over standard Cat6 network cables to a Network Video Recorder (NVR). They offer superior 4K clarity, digital zoom without pixelation, and smart AI features like facial detection and tripwire motion alerts. Ideal for large offices, multi-story houses, and industrial units.

Don't fall for low-quality desktop hard drives. CCTV systems require surveillance-grade hard drives (like Western Digital Purple or Seagate SkyHawk) designed for 24/7 continuous writing.
- 4 Cameras (2MP HD) + 1TB Hard Drive: Approx. 12 to 15 days continuous recording.
- 8 Cameras (2MP HD) + 2TB Hard Drive: Approx. 15 to 20 days continuous recording.
- 8 Cameras (5MP IP H.265+) + 4TB Hard Drive: Approx. 25 to 30 days continuous recording.
4. Night Vision Quality: Infrared vs Full-Color Night Vision
Standard IR cameras record black-and-white footage in the dark. Modern Full-Color / ColorVu cameras feature built-in warm LED lights that allow the camera to record vivid, full-color HD footage even in 100% pitch dark environments—making license plates and clothing colors easy to identify.
5. Live Mobile Monitoring Configuration
Never accept a CCTV installation without mobile app integration. At Radhe Computer, every installation includes complete router configuration so you can view live camera feeds, receive motion alerts, and play back historical video from anywhere in the world on your smartphone.
