How to Size a CCTV Camera System
  • Cover every entry (doors, gates, loading, garage).
  • Cover approach paths (driveway, walkways, parking lanes).
  • Cover high-value areas (register, inventory, tools, docks).
  • Fix blind spots at corners and transitions.
2–4 Cameras
Small coverage: key entry points + one approach path.
8 Cameras
Full perimeter basics + key interior areas.
16–32 Cameras
Multi-zone coverage for larger businesses and facilities.
DVR Recording: What matters most
DVRs record video locally and make it easy to search and export footage when you need it. Prioritize:
  • Channel count (buy with room to expand).
  • Remote viewing (optional internet access for mobile/desktop).
  • Playback speed and easy search tools.
  • Audio support if you’re using built-in microphone cameras.
Storage & Retention Planning
Retention depends on (1) camera count, (2) resolution, (3) recording mode (continuous vs motion), and (4) activity level. For longer retention, consider motion recording and choosing storage that matches your goals.
Installation Tips (Pro Results)
  • Mount cameras high enough to reduce tampering but low enough to capture usable faces.
  • Aim for faces at entries and activity in approach lanes (driveway/walkway).
  • Avoid pointing IR cameras at reflective surfaces to reduce night glare.
  • Label your cables and document camera zones for faster troubleshooting later.

CCTV System FAQs
How many cameras do I need?
Start with every entry and approach path, then add coverage for high-value areas and blind spots. Most homes start at 4–8 cameras; businesses often start at 8–16+.
Do CCTV systems need internet?
No. DVR recording is local. Internet is optional for remote viewing.
Can I expand my system later?
Yes—if your DVR has open channels you can add cameras later without replacing the entire system.
