How many CCTV cameras does a Sydney house need?

By Brendan Byrne · Published 10 September 2026 · 6 min read

Most Sydney houses need somewhere between 4 and 8 cameras, and the right number depends on your property's layout far more than its size in square metres. A single-fronted terrace with one side passage needs a very different setup to a freestanding house with a driveway on each side.

What does a typical Sydney house layout need covering?

Every property has a handful of points that matter more than the rest: the front door, the driveway or street frontage, any side passage or gate, and the back door or rear yard access. A semi-detached house usually has fewer of these points than a freestanding home, simply because shared walls remove some of the access options an intruder would otherwise have.

How many cameras does a semi or terrace need?

A single-fronted terrace or semi typically needs 4 cameras: one covering the front door and street frontage, one on the side passage if there is one, one covering the rear yard, and one covering the back door or laundry entry. Terraces often have a narrow side passage that's the realistic weak point, since it's out of view from the street and gives easy access to the back of the house, so that camera earns its place even on a tight budget.

How many cameras does a freestanding house need?

A freestanding house with a driveway usually needs 6 cameras: front door, driveway, one or both side passages depending on the block, rear yard, and back door. Corner blocks or homes with a second street frontage sometimes need a seventh camera to cover that additional exposure. Six cameras is the most common number we see specified for a standard freestanding Sydney block in the 400 to 700 square metre range.

What about duplexes and larger blocks?

Duplexes need cameras covering both the shared driveway and each unit's individual entry, which often pushes the count to 6 or 8 depending on whether the two households want fully separate systems or a single shared one covering common areas. Larger blocks, acreage properties or homes with a pool, shed or detached garage often land at 8 or more cameras once those secondary structures are included, since an empty shed or unmonitored pool gate is exactly the kind of blind spot worth closing.

Where exactly should cameras go?

The driveway camera should sit high enough to see the full width of the driveway and, ideally, the street beyond it, so it catches any vehicle approaching the property, not just one parked in the driveway itself. A front door camera works best angled to catch a visitor's face as they approach rather than looking straight down, which only ever captures the top of someone's head. Side passage cameras need to cover the full length of the passage, not just the gate, since a narrow field of view can leave the middle of the passage as an unmonitored gap. Rear yard cameras should cover the boundary fence line as well as the back door itself, since fence lines are a common point of entry that's easy to overlook.

Should I add a doorbell camera as well?

A video doorbell is a useful addition but shouldn't be your only front-of-house coverage. Doorbell cameras have a narrower field of view than a dedicated CCTV camera and, on most consumer models, a limited free recording window before you're asked to pay for cloud storage. Most Sydney homes we see run a doorbell camera for the immediate front-door interaction, package deliveries and visitor identification, alongside a full CCTV system that records continuously to its own local recorder and covers the wider property.

Why does camera overlap matter?

Overlapping coverage between two neighbouring cameras, even by a metre or two, closes the gap that a single camera's edge-of-frame distortion or blind spot could otherwise leave open. It also means that if one camera is obstructed, knocked out of position or has its view blocked by foliage that's grown over time, the adjoining camera still has partial coverage of that area rather than leaving it completely unmonitored. A good installer will plan for this overlap rather than treating each camera as covering an entirely separate zone.

What does a site walk actually check?

A proper site walk involves an installer walking the property with you, checking the sightline from each proposed camera position, working out where power and network cabling can realistically be run without unnecessary drilling or exposed cable, assessing lighting conditions at night since most break-ins happen after dark, and checking for gaps or overlap between camera positions before anything is mounted. For strata properties, the site walk also needs to account for by-laws about what can be mounted on common property versus your own lot, which is worth raising early rather than after a camera's already gone up.

Once you've worked out roughly how many cameras your property needs, it's worth reading our comparison of UniFi Protect, Hikvision and Dahua to decide which system suits the number and type of cameras you're after, and our guide to CCTV installation cost in Sydney to get a sense of what a system at this scale typically costs installed. If you live in an apartment or strata block rather than a standalone house, our guide on CCTV for strata and apartments covers the by-law side in more detail, and our top 5 CCTV installers in Sydney page is a good place to find someone to run the site walk itself.

Frequently asked questions

Is 4 cameras enough for a house? For a smaller semi or terrace with one main entry point, 4 cameras covering the front door, driveway or street frontage, side passage and back door is often enough. Larger freestanding homes or properties with multiple access points usually need 6 to 8 to avoid leaving a gap.

Do I still need CCTV if I have a video doorbell? A video doorbell covers your front door well but has a narrow field of view and usually a limited recording window unless you pay for cloud storage. Most Sydney homes use a doorbell camera alongside, not instead of, a proper CCTV system that covers the driveway, side access and rear yard on its own recorder.

Where do most break-ins happen on a Sydney property? Side passages, rear yards and unlit driveways are the most common points of entry, largely because they're out of view from the street and give an intruder time to work without being seen by neighbours. These are the areas a site walk should prioritise even if the front door feels like the obvious spot for a camera.

What does a CCTV installer's site walk actually check? A proper site walk checks sightlines from each proposed camera position, where power and network cabling can realistically run, lighting at night, overlap between cameras to avoid blind spots, and any strata or council restrictions that might apply to where cameras can be mounted.
