Buying the right CCTV camera system for your home, office, or factory in Panipat requires understanding a range of technical specifications including resolution, lens type, night vision range, storage, power, and brand reliability. This practical guide cuts through the jargon to help you make an informed purchasing decision in 2025.
Expert Tip from Eliza Infotech
Do not just buy the cheapest camera. A poorly installed, low-quality CCTV system that fails at night or produces blurry footage is worse than having no system at all. Invest in the right hardware from the start.
1. Choose the Right Camera Type
| Camera Type | Best Use | Field of View |
|---|---|---|
| Dome Camera | Indoor ceilings – offices, reception areas, schools | 90-120 degrees |
| Bullet Camera | Outdoor walls – gate entrances, parking, warehouse facades | Long-range narrow |
| PTZ Camera | Large open areas – factory grounds, parking lots | 360 degree motorized |
| Wi-Fi Camera | Indoor monitoring – baby monitor, home security | Depends on model |
| Fisheye Camera | Single camera for 360 degree room coverage | 360 degrees |
2. Megapixels and Resolution
- 1MP (720p): Entry-level. Good for indoor rooms where you just need presence detection.
- 2MP (1080p Full HD): The current standard for most homes and small offices.
- 4MP (2K): Excellent for shops, showrooms, and school corridors. Plate numbers readable at 10-15m.
- 8MP (4K Ultra HD): Premium. Best for bank branches, government buildings, and large warehouses in Panipat.
3. Night Vision – IR Range Matters
- 20m IR: Small rooms and corridors
- 30-40m IR: Average-sized outdoor areas
- 60m+ IR: Factory compounds, large parking areas
- Colour Night Vision: Uses ambient light to produce colour images in low light (ideal for entrance areas with streetlights)
4. DVR vs NVR
DVR (Digital Video Recorder) is used with traditional coaxial cable cameras. It is more affordable and suitable for smaller setups (2-8 cameras). NVR (Network Video Recorder) is used with IP cameras. It transmits video data over ethernet or Wi-Fi and supports higher resolutions. For new installations in Panipat in 2025, NVR with IP cameras is generally recommended for scalability.
5. Storage Calculation
Estimate your HDD requirement: Camera count x 30GB per day per camera. So 4 cameras x 30 days x 30GB = ~3.6TB. Budget for a 4TB or 6TB surveillance-grade HDD. Use Western Digital Purple or Seagate SkyHawk series – standard desktop HDDs fail under 24/7 recording stress.
6. Best CCTV Brands at Eliza Infotech Panipat
- Hikvision – World’s #1 selling CCTV brand. Excellent software ecosystem (Hik-Connect app), wide product range.
- CP Plus – India’s most popular brand. Great value for money, strong after-sales support.
- Dahua – Premium AI-powered cameras with face recognition, ANPR, and perimeter detection.
7. Red Flags – What to Avoid
- Unknown Chinese clone brands from street markets – no warranty, no app support, firmware security risks
- Buying without a site survey – camera placement matters more than camera quality
- Skipping an AMC contract – cameras need annual cleaning, HDD checks, and firmware updates. Sign up for a CCTV AMC plan
- Using domestic-grade HDDs – they fail within 6 months under 24/7 recording stress
