If you run a small business, CCTV shouldn’t feel like a tech project. You need clear footage, reliable recording, and easy playback—not fancy features you’ll never use.
Here’s the practical setup that works for most Aussie shops, cafés, clinics, workshops, and small warehouses.
The “just right” CCTV setup (most small businesses)
1) Camera count: usually 4–8 cameras
-
4 cameras: small shopfront or café
-
6 cameras: shop + stock room + back entry
-
8 cameras: small warehouse / workshop / more entrances
If you’re under 4 cameras, you almost always miss something (back door, stock room, side access).
2) The 4 most important camera locations
Don’t start with corners. Start with risk zones:
-
Front entry (face capture)
-
Point of sale / counter area (not the whole floor—focus on transactions)
-
Stock room / high-value storage
-
Rear door / delivery entry
Then add:
-
carpark / loading area (if you have one)
-
side access / alley (common sneaky entry)
3) Recording: NVR + wired PoE is the standard
For business CCTV, wired PoE + NVR wins because:
-
it records 24/7 reliably
-
it keeps recording even if the internet drops
-
video quality stays stable with multiple cameras
Wireless is fine for one camera or temporary coverage, but it’s not the best base for business evidence.
4) Storage retention: aim for 14–30 days
Most small businesses should target:
-
14 days minimum (better than “we only have last week”)
-
30 days if you deal with chargebacks, disputes, or incidents noticed late
Storage depends on camera count, resolution and whether you record 24/7—use your storage calculator to size it properly.
What’s worth paying for (and actually helps)
-
Human/vehicle detection (reduces false alerts)
If you want notifications that aren’t annoying, get AI filtering.
-
Good low-light performance
If you have any dark areas (rear door, carpark), low-light performance matters more than megapixels.
-
A simple playback/search experience
The ability to quickly find “person at back door at 2am” matters more than the fanciest spec.
-
UPS backup (if outages happen in your area)
A small UPS can keep your NVR and router alive long enough to keep recording through short outages.
What’s usually overkill for small businesses
-
8MP/4K everywhere
4MP or 6MP is enough for many areas. Use 8MP only where you need wide coverage + zoom (like a carpark or big warehouse bay).
-
Facial recognition
For most small businesses, it’s unnecessary and can raise privacy concerns. You usually just need clear face footage at entry.
-
“Cloud-only” subscription systems for multi-camera setups
Subscriptions add up fast, and you’re dependent on internet. For 4+ cameras, local NVR recording is usually the smarter long-term option.
-
One camera trying to cover everything
Wide shots look nice but often fail when you zoom in. Better: one overview + one closer identification angle in key zones.
Quick buying checklist
Before you buy, answer these:
-
How many entrances do you have (front + back + side)?
-
Where is your highest-value area (stock/cash/tools)?
-
Do you need 14 or 30 days retention?
-
Will cameras be exposed to weather/coastal conditions?
-
Do you want alerts after hours (human/vehicle detection)?
If you can answer those, the system spec becomes easy.
Recommended “starter packages” by business type
Small shop / café (most common)
-
4–6 PoE cameras
-
8-channel NVR (room to grow)
-
2TB–4TB HDD depending on retention target
Workshop / warehouse / medical practice
-
6–8 PoE cameras
-
8-channel NVR
-
4TB–8TB HDD for 30 days if recording 24/7
Bottom line
For most Australian small businesses, the best CCTV setup is wired PoE cameras + NVR + 14–30 days storage, placed at entry, counter, stock, and rear door.
Everything else—4K everywhere, facial recognition, cloud-only subscriptions—tends to be overkill unless you have a specific reason.
