Good to Know Before Buying
- All systems below record locally (no subscriptions required)
- Most smart alerts and AI detection happen inside the cameras, not the NVR
- PoE = one cable for power + video (simpler, more reliable)
- Wired NVR systems are more stable than battery or Wi-Fi cameras
How to Choose the Right 4-Channel NVR
How many cameras do you need?
- 1–4 cameras → ideal use case
- Always leave at least one channel free for future expansion
Is 4K really worth it?
- Yes if you want to zoom into faces or license plates
- 1080p saves money but loses detail quickly
Do smart alerts matter?
- Smart detection reduces false alerts from shadows, rain, or pets
- Person/vehicle detection is the most useful feature
How much storage is enough?
- 2TB ≈ ~7–10 days for four 4K cameras recording 24/7
- Look for expandable HDD support for longer retention
PoE vs non-PoE
- PoE is strongly recommended for reliability and clean installs
