Most home CCTV systems sold in Sydney are over-specified, under-installed, or both. Knowing what actually matters before you buy makes the difference between security and a noisy gadget.

Home CCTV has moved a long way since the grainy black-and-white systems of the 2000s. A current four-camera setup gives you 4K colour footage, intelligent person detection, and remote access from anywhere in the world. For most Sydney homes, that is the sensible starting point.
This guide covers the specs that matter, the ones that do not, where wireless cameras make sense versus where cabled is the only realistic option, and how to think about storage, mobile access, and insurance documentation.
Most Sydney homes are well covered by four cameras. Front door, rear door, driveway, and one wider view of the backyard or pool area. Anything more starts to become administrative overhead. Anything less leaves blind spots that an intruder will find.
Larger blocks with side gates, granny flats, or long driveways often need a six or eight camera setup. Smaller terraces and units in higher-density Sydney suburbs are often fine with two well-placed cameras at the entry points. The right number is what covers every approach without overlap.
4K cameras have come down in price enough that we install them as standard now. The extra resolution is not about looking sharper on screen. It is about being able to digitally zoom into a recorded clip and still identify a face, a number plate, or a clothing detail well enough for a police report or insurance claim.
Anything below 1080p struggles to deliver usable detail past about four metres. Anything above 4K is overkill for residential use and uses far more storage than the extra detail justifies. Four megapixel to eight megapixel is the practical sweet spot.
Sydney burglaries skew heavily toward overnight hours. A camera that produces useless footage after dark is not a CCTV system. It is a daytime gadget.
Standard on most current cameras. Renders the scene in black and white using invisible infrared light. Works to about twenty to thirty metres depending on the camera. Good for general coverage, useless for capturing colour detail.
Newer cameras use larger sensors and built-in white LEDs to deliver full colour footage even at very low light levels. The white LED can also act as a deterrent, illuminating an intruder the moment motion is detected. Worth the upgrade on entry points.
Cameras with built-in spotlights and speakers can trigger lights, sirens, or pre-recorded warning messages when they detect a person on the property. For homes that have had previous incidents, this layer can be the difference between an intruder approaching and one walking away.
Wireless cameras are easier to install, but they depend on a stable WiFi signal and a constant power source. They also drop offline more often than cabled cameras. For high-value positions like the front door and driveway, cabled is the safer choice.
Power-over-Ethernet, or PoE, runs a single cable for both power and data. We run PoE through the roof cavity in most installs, which gives reliable footage with no batteries to charge and no WiFi drop-outs. Wireless cameras work well for difficult positions where running cable is genuinely impossible.
On-site recording on a network video recorder, or NVR, is still the standard for serious CCTV. The NVR holds two to four weeks of footage, depending on resolution and number of cameras, and continues recording even if the internet drops out.
Cloud recording is useful as a secondary backup, particularly if an intruder steals or damages the NVR itself. Combining a local NVR with selective cloud upload for motion events gives the best balance of cost, reliability, and footage availability. Every system we install includes mobile app access for live view and clip playback from anywhere.
An insurance claim after a break-in usually requires footage that clearly shows the offender, the time and date of the incident, and the items taken or damaged. A 4K cabled system with accurate timestamps and remote backup ticks every one of those boxes.
We document every camera position, hand over the system schematic, and walk through the mobile app on commissioning. If you ever need to provide footage to police or an insurer, you know exactly which clip to export. That is the system working the way it should.
If your safety switch is more than ten years old, or it trips for no obvious reason, it is already telling you something.
Most EV owners do not think about their home charger until the car arrives in the driveway. By that point, the install is a rush, and rushed installs go wrong.
Federation cottages, post-war fibros, 1970s brick veneers. They share one thing. Their switchboards were not built for 2026.
