Buying your first CCTV camera can feel overwhelming — 2MP or 5MP? Dome or bullet? Analog or IP? The good news is that choosing the right camera comes down to five simple questions. Answer these and you’ll never overpay for features you don’t need, or under-buy and regret it later.

1. Where will the camera go — indoor or outdoor?
This is the first fork. Outdoor cameras need a weatherproof metal body (look for an IP66/IP67 rating) to survive rain, dust and heat. Indoor cameras can be smaller and lighter. Bullet cameras are visible and act as a deterrent outside; dome and eyeball cameras look neater indoors and are harder to tamper with. If you’re covering a mix of both, that’s completely normal — most homes use a blend.
2. What resolution do you actually need?
Resolution decides how much detail you capture — crucial for reading a face or a number plate. 2MP (1080p) is fine for general coverage; 5MP and 4K let you zoom in and still see detail. But higher resolution also needs more storage. We break the trade-off down fully in our guide to 2MP vs 5MP vs 4K CCTV cameras — worth two minutes before you decide.
3. Analog (HD) or IP?
Two families of cameras exist. HD analog cameras run over coaxial cable to a DVR — they’re affordable, proven, and ideal for homes and small shops. IP cameras run over network cable to an NVR, offer higher resolutions and features like smart detection, and are the choice for larger or future-proof installs. Neither is ‘better’ — it depends on your budget and how much you want to scale.
4. How good is the night vision?
Most incidents happen after dark, so night performance matters more than almost anything. Standard infrared (IR) gives clear black-and-white footage at night. Newer full-colour and dual-light cameras keep colour at night using a warm spotlight — far more useful for identifying clothing or vehicles. If night identification is important to you, spend here rather than on raw megapixels.
5. Where will the footage be stored?
Cameras are only half the system — you need a recorder and a hard disk to keep the footage. A 1TB disk stores roughly 8–10 days on a 4-camera setup; 2TB and 4TB store proportionally more. Decide how many days of history you want before you buy, and size the disk to match. WiFi cameras can also record locally to a microSD card if you don’t want a DVR.
Quick reference: match the camera to the job
| Your situation | Best fit |
|---|---|
| Home, tight budget, 2–4 cameras | 2MP HD analog + DVR |
| Home/shop, want to zoom into detail | 5MP HD or IP |
| Business, many cameras, smart features | 4MP+ IP + NVR |
| No wired internet at the site | 4G SIM or WiFi camera |
Don’t forget brand and warranty
A camera is a long-term investment that runs 24×7, so buy a genuine unit from a brand with real service support — Hikvision, CP Plus, Dahua and Prama are all dependable choices in India. Always insist on a proper invoice so your warranty is valid.
How many cameras will you need?
Once you’ve picked the type, the next question is coverage. Our room-by-room camera count guide helps you plan the right number without blind spots — or overspending.
Frequently asked questions
Is a 2MP camera enough for home?
For most homes, yes — 2MP covers gates, doors and rooms clearly. Choose 5MP only if you specifically need to zoom into faces or number plates.
Do I need internet for CCTV?
No — CCTV records locally without internet. You only need internet if you want to view the footage remotely on your phone.
Can I mix camera brands?
Cameras and recorder should ideally be the same brand for full compatibility. Accessories like HDDs, cables and UPS can be any brand.
