Most Australian homes need four to six security cameras, and businesses scale from there based on entry points and risk. The real question is not just "how many" but "where" — good coverage beats a big number. Here is a simple way to work it out, with genuine Hikvision gear from an authorised Hikvision reseller.
The quick guide by property type
| Property | Typical cameras | Cover first |
|---|---|---|
| Apartment / townhouse | 2–4 | Front door, balcony/garage, hallway |
| Standard home | 4–6 | Front door, driveway, back yard, side access |
| Large home | 6–8 | All entries, garage, perimeter corners |
| Small business / shop | 4–8 | Entrance, register, stockroom, blind spots |
| Warehouse / large site | 16+ | Gates, loading docks, aisles, perimeter |
How to work out your number
- List every entry and exit — doors, gates, garages. Each usually needs a camera.
- Add high-value and blind-spot areas — driveways, back yards, registers, stockrooms.
- Choose the right camera per spot — a long AcuSense bullet for driveways, a ColorVu camera at the door for full-colour night footage.
- Leave NVR headroom — pick a recorder with spare channels so you can add cameras later.
Match your cameras to a recorder
Once you know your camera count, choose an NVR with at least that many channels plus room to grow — our NVR channels & storage guide makes it easy. New to picking cameras? Start with the best Hikvision cameras for home security, and see what a full system includes in our CCTV kits guide.
Frequently asked questions
How many security cameras do I need for a house?
Most homes are well covered by four to six cameras: the front door, driveway, back yard and side access points. Larger homes with more entry points may want six to eight.
How many cameras does a business need?
It depends on the site. Map every entrance, till or register, stockroom and blind spot — a small shop may need four to eight, while a warehouse can need dozens. Plan by zones and risk.
Where should I place security cameras?
Cover every entry and exit first, then high-value areas and blind spots. Mount cameras high enough to avoid tampering but angled to capture faces and plates, not just the tops of heads.
Do more cameras need a bigger NVR?
Yes. Choose an NVR with at least as many channels as cameras, with room to grow. See our NVR channels and storage guide to size it correctly.
Is it better to have fewer high-resolution cameras or more cameras?
A balance works best — use higher-resolution cameras to cover wide or critical areas, and add more cameras to remove blind spots. Coverage matters more than raw camera count.
