This is the fork in the road every CCTV buyer hits, and picking wrong means rewiring everything later.

Let me break down the real difference without the sales pitch.

Analog (HD-CVI/TVI): cheaper, simpler

Analog cameras send video over coaxial cable to a DVR. They're cheaper, the tech is mature, and for a small home setup they're perfectly fine. The trade-off is lower maximum resolution and less flexibility.

IP cameras: higher quality, more features

IP cameras run over network cable (or Wi-Fi) to an NVR. You get higher resolution, smarter analytics (line-crossing, intrusion detection), and easier remote access. The cost is higher and they need a proper network setup.

Which should you pick?

Small home on a tight budget → analog is fine. Business, larger property, or you want smart detection and crisp footage → go IP. Most modern buyers lean IP because the price gap has narrowed.

Either way, brand reliability matters more than the format debate. This Dahua security camera range carries both analog and IP options, so you can pick the format that fits your wiring and budget.
