Picking a CCTV camera feels overwhelming because every listing throws spec jargon at you, so let me cut through it.

Here's the simple decision framework I wish someone had given me before my first purchase.

Step 1: Decide indoor vs outdoor

Outdoorcameras need weatherproofing (look for IP66/IP67 ratings) and better night vision. Indoor ones can be smaller and cheaper. Map your property first and mark every spot you want covered.

Step 2: Pick resolution by purpose

2MP (1080p) is fine for general coverage. Go 4MP+ only where you need fine detail like faces at the gate or number plates. Higher resolution eats more storage, so it's a trade-off, not a "more is always better" thing.

Step 3: Don't forget the recorder and storage

People obsess over cameras and forget the DVR/NVR, which is what actually keeps your footage. Buy enough storage for at least 2 to 4 weeks of recording.

Step 4: Match it to a reliable brand

Once you know your specs, choosing is easy. If you want to buy dahua camera models, they're organized by type so you can match the spec you decided on above to a real product. Get these four steps right and you'll avoid the most common beginner mistakes. Drop your home layout below and I'll suggest a camera count.
