How Many CCTV Cameras Do You Need for Your Home?

Working out the right number of cameras comes down to coverage, not just floor space — a single well-placed camera can watch two approach angles at once, while a poorly placed one leaves blind spots even with extra units nearby.

Start With Entry Points

Front door, back door, and any side gates or garage entries are the priority. These are the points every intruder has to pass through, and they're also where package theft and doorbell-related incidents happen most.

• Front door / porch — wide-angle camera with a clear view of the approach
• Back door and side gates — motion-triggered coverage of less-visible entries
• Driveway and garage — covers vehicles and deliveries

Then Cover the Perimeter

For a typical Adelaide quarter-acre block, 4 cameras usually covers front, back, and both side access points. Larger properties or corner blocks often need 6-8 to remove blind spots along longer fence lines.

Don't Forget Resolution

Camera count matters less than most people think if the resolution is too low to identify a face or number plate at your property's actual distances. A 4-camera 6MP system will often out-perform an 8-camera 2MP system for anything you'd actually need footage for.

Our Recommendation

Most Adelaide homes land in the 4-6 camera range. Commercial properties and larger acreages typically need a proper site assessment — camera count, resolution and hard drive size can all be configured together in our online quote calculator, or a technician can walk your property and recommend exact placement.
