Good to Know Before Buying

  • All systems below record locally (no subscriptions required)
  • Most AI detection happens 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 NVR System

How many cameras do you need?

  • 4–8 cameras → most homes
  • 8–16 cameras → large homes or businesses
  • Always leave extra channels 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 fast

Do AI features matter?

  • AI helps reduce false alerts from shadows, rain, or trees
  • Person/vehicle detection is the most useful feature

How much storage is enough?

  • 2TB = ~7–10 days for 4 cameras at 4K (24/7)
  • Look for expandable HDD support if you want longer retention

PoE vs non‑PoE

  • PoE is strongly recommended for reliability and clean installs
