Home Security Systems in Sydney: A Guide for Modern Homes
Home Security Systems in Sydney: A Guide for Modern Homes
Keeping your home secure used to be fairly straightforward. A basic alarm, a sturdy lock and some sensible lighting were often enough. Today, home security systems look very different. Cameras, smart doorbells, wireless sensors and App-based monitoring are becoming the new normal across Sydney, and homeowners now have access to technology that can genuinely improve safety and peace of mind.
With this shift comes an important question. Which home security systems actually work in Sydney homes, and when should a licensed electrician be involved? Faraday Group has supported Sydney households for more than sixty years, and we see firsthand how modern security technology fits into real homes, not just brochures. This guide will help you understand the options available and choose the mix of security features that makes sense for your property.
What Makes Up a Modern Home Security System
A home security system is no longer a single device. It is usually a collection of interconnected parts that work together to protect your home. The most common components include:
Security cameras
These are now available in wireless, wired, indoor and outdoor versions. They provide live viewing, motion alerts and recorded footage. More recent models use AI to distinguish between people, pets, vehicles and general movement.
Video doorbell cameras
These give you real-time visibility of visitors at your front door. Many homeowners treat them as a first line of defence because they also capture footage of deliveries, unexpected visitors and attempted break-ins.
Smart alarms and sensors
Motion sensors, window sensors and door sensors form the backbone of a traditional alarm, but they can now be integrated with mobile apps and automated routines.
Smart locks and access control
Keypad and fingerprint locks are becoming more common in Sydney, particularly in homes where family members or short-term guests come and go.
Security lighting
One of the simplest and most effective deterrents. Modern systems can include floodlights with built-in cameras, pathway lighting and motion-activated lights.
Each of these categories has pros and cons, and the right mix depends on your property layout, wiring, Wi-Fi coverage and the level of visibility you want.
Security Cameras: The Fastest Growing Trend in Sydney
Interest in security cameras has increased sharply over the last couple of years. The technology has become more affordable, easier to install and much more intelligent. Modern cameras now offer:
- High resolution video, often 2K or higher
- Night colour vision rather than basic infrared
- AI detection that reduces false alerts
- Wider lenses that capture more of your entry areas
- Local storage options that avoid subscription fees
- Weather-rated casings for outdoor installation
Wired versus wireless
Wireless cameras suit renters or homes where drilling is not ideal. They rely on Wi-Fi and battery or solar power. Wired cameras (often PoE, powered over Ethernet) provide stronger reliability and uninterrupted recording. Many of Sydney’s older homes, including terraces and semis, benefit from wired systems because internal walls and long, narrow layouts can create Wi-Fi dead zones.
Faraday Group is often called to install outdoor power for cameras, run safe cabling for wired systems or upgrade switchboards when older homes cannot support additional load. This work must follow NSW electrical safety rules, and professional installation ensures equipment performs as intended.
Video Doorbell Cameras: What to Know Before You Buy
Video doorbells have become one of the most popular home security upgrades across NSW. They offer a simple combination of convenience and protection. Key features usually include:
- Live video of your front door
- Two-way audio
- Motion alerts
- Package detection
- Visitor history
- Night vision
Some models can be installed with adhesive mounts or existing screws and operate on rechargeable batteries. Others can be hardwired into your current doorbell circuit. This is where homeowners often become unsure, because any hardwired installation must comply with NSW electrical regulations.
Battery doorbells are typically fine for DIY, although placement and Wi-Fi strength can affect performance. Hardwired doorbells, especially those that require a transformer or connection to a chime, should be installed by a licensed electrician. Faraday Group frequently supports homeowners who want a clean, safe and tidy installation that avoids exposed cabling and ensures reliable charging.
Alarms and Smart Sensors: Still an Important Foundation
Alarms remain an essential part of many home security systems in Sydney. Modern alarm systems can operate as standalone devices or integrate with cameras and smart home platforms such as Google Home, Apple Home or Amazon Alexa.
Typical components include:
- Door and window sensors
- Motion sensors
- A control panel
- A siren or outdoor strobe
- Optional smoke detection integration
If you have an older alarm that uses outdated wiring or a panel that no longer supports modern sensors, it may be worth replacing rather than repairing. Some new systems operate on Wi-Fi, although anything requiring power or physical cabling is safest when installed by a professional.
Smart Locks and Access Control
Smart locks have become especially appealing for busy households, families with teens and homes used for short-term rentals. Features can include:
- PIN entry
- Fingerprint unlocking
- Phone-based access
- Temporary access codes
- Auto locking
- Integration with doorbell cameras
The installation process varies widely. Some locks require no electrical work at all. Others need a power source, particularly if they include cameras or use features beyond simple battery operation. When external wiring or modifications to a door frame or strike plate are required, Faraday Group can advise on the safe way forward.
Security Lighting and Outdoor Safety
Lighting continues to be one of the most effective deterrents against break-ins. The right lighting strategy often works better than a camera on its own because it eliminates hiding spots and makes CCTV footage clearer.
Popular options include:
- Motion-activated floodlights
- Wall-mounted perimeter lights
- Integrated light and camera combinations
- Pathway or landscape lighting for visibility
Outdoor lighting must be weatherproof, safely wired and installed according to NSW electrical standards. Faraday Group regularly installs security lighting for Sydney homes, particularly for older properties where outdoor power access is limited.
Choosing the Right System for Your Home
Before purchasing a home security system, consider the following:
Property type
Terrace houses often require wired solutions because of thick brick walls. Apartments may have strata rules restricting external cameras. Freestanding homes usually have more flexibility.
Wi-Fi strength
Many security failures come from weak Wi-Fi. You may need additional access points or cabling to ensure reliable camera operation.
Power and cabling
If you plan to install wired cameras, doorbells, lighting or alarms, check whether your home has suitable power access and whether external wiring will be exposed.
Storage preferences
Some homeowners prefer systems with local storage on SD cards. Others do not mind cloud-based subscriptions.
Smart home integration
If you already use Apple Home, Google Home or Alexa, choose equipment that works smoothly with your ecosystem.
When to Call a Licensed Electrician
There is a place for DIY in home security, but there are also clear situations that require professional support. You should contact a licensed electrician, such as Faraday Group for:
- Hardwired video doorbell installation
- Outdoor security lighting
- Installing wired security cameras or PoE systems
- Upgrading switchboards to safely support security equipment
- Running new cabling through walls or outdoor areas
- Adding external power points
- Ensuring equipment is weather-safe and compliant
Faraday Group’s technicians make sure all work complies with NSW regulations and that systems operate reliably long term.
A Brief Note on NSW Privacy and CCTV Rules
Sydney homeowners should be aware of basic privacy considerations when installing cameras.
Your cameras must not record neighbours in private areas such as inside their home or in spaces where they reasonably expect privacy. NSW has clear rules regarding surveillance devices, and it is worth reviewing official guidance before installation.
