Home Security Cameras

A home security camera system today is a different proposition than five years ago. AcuSense AI on the camera filters motion alerts down from "every passing animal and weather event" to "humans and vehicles only" — your phone notifications stop firing on possums and wind. ColorVu cameras stay in full colour at night instead of switching to black-and-white IR — capturing clothing colour, vehicle colour and other identification detail that matters when something does happen. NVR-based systems retain weeks of footage on a single hard drive, with mobile app access for live view and playback from anywhere. The DIY install is achievable in a weekend for typical single-storey homes; professional install is the right call for two-storey, brick-veneer or solid-brick, or where the cable routing complexity warrants it.

Security Cameras Australia stocks the residential range from value-tier HiLook and Tapo through premium-tier Hikvision and Axis. Every kit is genuine Australian stock with manufacturer warranty.

What a typical home install looks like

Most homes work well with one of three configurations:

Entry-point kit (1-2 cameras)

Front door and one other position — back door, driveway, or side gate. Suits apartments, townhouses, or homeowners wanting visibility at the highest-risk position only. Single-camera setup with mobile app live view; usually wireless or single-line PoE.

Perimeter kit (4 cameras)

Front door, back door, two side perimeters — covers the four sides of a typical single-storey home. 4-channel NVR + 4 PoE cameras + 30-day retention. The most common residential install. DIY-installable for accessible single-storey homes; professional install $1,500-3,000 typical for two-storey or complex routing.

Full coverage (6-8 cameras)

Four-side perimeter plus driveway entry, back-yard view, garage interior, and additional high-value positions. 8-channel NVR + 6-8 PoE cameras + 30-60 day retention. Larger homes, properties with multiple buildings (garage, granny flat, shed), or owners wanting full property coverage. Professional install standard at this scale.

How to choose the right cameras

Resolution

4MP for short-range and budget-conscious installs (most front-door positions are within 4MP's identification range). 6MP for the standard home — slightly more headroom at distance, the most common buy. 8MP / 4K for long driveways, larger properties, or wanting maximum detail.

AcuSense (AI alert filtering) — yes or no

For outdoor cameras, almost always yes. AcuSense classifies motion as human/vehicle/other, cutting false alerts up to 95%. Without AcuSense, every passing animal, wind-blown branch and weather event triggers a notification — within a week most owners just ignore the alerts. With AcuSense, notifications become worth checking. The cost premium is modest. See AcuSense.

ColorVu (full-colour night vision) — yes or no

For front-of-house identification positions, often worth it. ColorVu keeps the camera in full colour at night via F1.0 aperture and supplementary white light — captures clothing colour, vehicle colour and other descriptive detail instead of B&W IR. The supplementary white LED also acts as a soft deterrent. Not ideal for covert or rear-perimeter positions where you don't want the visible light. See ColorVu.

Camera form factor

Turret cameras for general perimeter — the most common buy, compact and discreet. Bullet cameras for long-range positions like driveway or long fence line. Dome cameras for ceiling or eave-soffit positions. PTZ for active properties wanting controllable wide-area coverage (rural properties with large coverage zones). See turret, bullet, dome, or PTZ.

Practical install considerations

DIY vs professional

DIY install is sensible for single-storey homes with accessible cable paths through roof spaces. The cameras and NVR are plug-and-play once cabling's run. Plan a weekend for a 4-camera install.
Professional install is the right call for two-storey homes, solid-brick or brick-veneer construction, complex cable routing, or where you want neat finished cable runs. Cost: $1,500-3,000 typical for a 4-camera system, more for larger.

Wired vs wireless

Wired (PoE): best image quality, continuous recording, no Wi-Fi dependency, no batteries to charge. The standard for permanent installs. Single Cat6 per camera carries power and data.
Wireless (Wi-Fi): no cable run to the camera, but needs mains power at the camera and reliable Wi-Fi coverage. Suits sites with power but no easy cable route — outdoor cameras within Wi-Fi reach, indoor cameras at power points. See wireless cameras.
Solar/4G: for positions with no power and no network — rural properties, sheds, remote gates. See solar cameras.

Storage and retention

Modern NVR-based kits include a pre-installed surveillance-grade hard drive (typically 2-4 TB) sized for 30-day retention at the camera resolution. For longer retention, upgrade the drive — surveillance drives like Seagate SkyHawk AI handle continuous 24/7 write loads. See CCTV hard drives.

Insurance benefit

Many Australian home insurers offer modest premium discounts for monitored CCTV systems. Talk to your broker — the discount over the system's life often offsets a meaningful portion of the install cost.

Common questions before you buy

Wi-Fi camera or wired NVR system?

Wi-Fi for 1-2 cameras at convenient positions, no commitment to a system. NVR-based for 4+ cameras or any install where reliability matters more than convenience. The crossover point in most homes is around 3 cameras — beyond that, the wired NVR architecture wins on cost, reliability and image quality.

Will I need a hard drive?

Wi-Fi cameras typically record to cloud (subscription) or an SD card (limited capacity). NVR systems record to a hard drive (included in most kits) — weeks of continuous footage on a one-time purchase, no subscription. For most homes, NVR storage beats cloud subscription on long-term cost.

Can I view cameras when I'm away?

Yes — Hik-Connect, the Hikvision and HiLook mobile app, supports live view and playback from anywhere with internet. Setup is QR-code-based via the app. No cloud subscription required for basic remote viewing.

Frequently Asked Questions about Home Security Cameras

How many cameras do I need for my home?

For most single-storey homes: 4 cameras (front door, back door, two side perimeters) covers the four sides. Larger homes, two-storey, or properties with multiple buildings (garage, granny flat, shed): 6-8 cameras to add driveway, side approaches, and high-value positions. Apartments or townhouses: 1-2 cameras at the main entry often enough. Start with 4 if unsure — the cost difference between a 4 and 6-channel NVR is modest and gives expansion room.

Can I install a home CCTV system myself?

For single-storey homes with accessible cable paths through roof spaces: yes, comfortably in a weekend. The cameras and NVR are plug-and-play once cabling's run; routing the Cat6 from NVR to each camera is the time consumer. For two-storey, brick-veneer or solid-brick construction, or any install where you want neat finished cable runs, professional install ($1,500-3,000 for a 4-camera system) is the right call. Many homeowners self-install single-storey and call professionals for two-storey.

Will the cameras keep recording during a power cut?

Only if the NVR is on a UPS (uninterruptible power supply). Without a UPS, the NVR loses power and stops recording until the mains comes back — typical brief outages mean 5-10 minutes of lost recording and a slight risk of hard drive corruption from unclean shutdown. A modest UPS adds proportionately small cost and gives the system 15-30 minutes of battery backup through brief outages. Worth considering for any install where recording continuity matters. See <a href="/collections/uninterruptible-power-supply">UPS for CCTV</a>.

Do I need a special hard drive in the NVR?

Yes — surveillance-grade drives like Seagate SkyHawk AI or WD Purple are designed for continuous 24/7 write loads from multiple camera streams. Standard desktop drives often fail prematurely in this use. Most NVR kits include a pre-installed surveillance drive; if you upgrade, specify surveillance-grade. Typical size: 4 TB for a 4-camera 4MP install at 30-day retention; 8 TB for 8-camera 4MP at 30 days. See <a href="/collections/hard-drives-for-cctv">CCTV hard drives</a>.

Will the cameras work if my internet goes down?

Yes for recording — the NVR records continuously to its hard drive regardless of internet status. What stops working: remote viewing via mobile app and cloud-based notifications. Live view at the NVR (connected to a TV via HDMI) keeps working. When the internet comes back, the mobile app reconnects automatically. For home installs where internet reliability is occasionally an issue, the on-NVR recording means you never lose footage even during a connection dropout.
