Dome Cameras
Dome cameras are the most popular CCTV camera type in Indian homes, offices, and retail stores. The hemispherical housing conceals the lens direction, preventing intruders from knowing exactly where the camera is aimed – a significant deterrence advantage. Vandal-resistant dome cameras (IK10 rating) withstand direct physical impact, making them ideal for Indian retail environments, parking lots, and stairwells.
Best for: Indoor halls, retail, reception areas, apartment lobbies. Weakness: Limited range (typically 15-20m effective view) and fixed viewing angle without pan-tilt capability.
Bullet Cameras
Bullet cameras are cylindrical, long-range CCTV cameras typically mounted on walls or ceilings pointing in a specific direction. Their distinctive shape acts as a visible deterrent – potential intruders clearly see they are being watched. Bullet cameras typically achieve better range than dome cameras (30-80m with varifocal lenses) and are preferred for Indian outdoor applications: compound gates, car parks, farm boundaries, and warehouse perimeters.
Best for: Outdoor compound, parking, long corridors, entrance monitoring. Weakness: Fixed aim direction – requires repositioning if coverage needs change. More vulnerable to vandalism than dome cameras.
PTZ Cameras
Pan-Tilt-Zoom (PTZ) cameras can remotely rotate (pan), tilt up/down, and zoom optically – providing active tracking capability. A single PTZ camera can cover the same area as 4-6 fixed cameras when actively monitored. Auto-tracking PTZ cameras use AI to follow moving subjects automatically without human operator intervention.
Indian cost: Rs 8,000-50,000 depending on optical zoom ratio (10x-40x), resolution (2MP-4K), and IR range. Most cost-effective for critical monitoring points that require flexible coverage: main gates of industrial facilities, hotel lobby intersections, and large outdoor areas.

Installation Considerations
For Indian climate conditions:
- Monsoon proofing: Use IP66 or IP67 rated cameras outdoors. Check junction box seals annually – Indian monsoon humidity degrades silicone seals faster than European climates.
- Sun exposure: Avoid mounting bullet cameras pointing east or west where direct sun enters the lens during morning/evening hours – use sun shields.
- Cable routing: In Indian RCC construction, route cables through EMT conduit where visible or through walls using a masonry drill. UV-rated outdoor cable is mandatory.
- Power supply: Indian 230V fluctuations can damage camera electronics. Use a UPS or voltage stabilizer for the DVR/NVR and PoE switch.

Frequently Asked Questions
How many cameras do I need for an Indian 3BHK flat?
Typically 4 cameras: front door (bullet or dome), back door/balcony, main hall, and parking/stairwell access. Priority order: main entrance first, then other entry points. Indoor cameras inside bedrooms require consent of all occupants.
What resolution CCTV should I buy in 2025?
2MP (1080p Full HD) is the minimum practical resolution for identification purposes. 4MP provides noticeably better detail at similar cost in 2025. 4K (8MP) is worth the premium only if you need to zoom into recorded footage for identification – storage costs are 4x higher than 1080p.
Is IP CCTV or HD-CVI/HD-TVI better for Indian homes?
For new installations in 2025: IP cameras (network video) are recommended. HD-CVI/TVI use analogue coaxial cable (like traditional CCTV) but at higher resolution – suitable only when reusing existing coaxial cable infrastructure. IP cameras offer better smart features, easier expansion, and cleaner installation with single Cat6 cable.
How far can IR night vision see?
Standard IR night vision in Rs 2,000-5,000 cameras: 20-30m effective range. Long-range IR bullet cameras (Rs 5,000-12,000): 50-80m. Professional IR with LED arrays: 100m+. For very dark environments without ambient light, use cameras with white light supplemental LEDs for colour night vision rather than IR.
What is the difference between H.264 and H.265 compression?
H.265 (HEVC) compresses video at approximately 50% smaller file size than H.264 at the same quality. For a 4-camera system recording continuously, H.265 roughly halves your storage requirement and network bandwidth. Newer cameras (post-2020) almost universally support H.265; verify your NVR also supports H.265 decoding before purchasing H.265 cameras.
