3 min readUpdated 04-Nov-2026

Start with entry points

  • Main gate and front door.
  • Back door, roof door or garage.
  • Car porch or parking.
  • For shops: counter, cash area and entrance.

Recording and night view

  • Recording days depend on hard disk size, number of cameras and quality.
  • Choose night vision cameras for gates and streets that are dark at night.
  • Outdoor cameras should be weatherproof.

Respect privacy

Cover your own property. Don't point cameras into neighbours' homes, windows or private spaces. A good installer helps you set angles that are fair to everyone.

Still stuck? A checked CCTV mistri can help.
