Do home security systems need to be wired by an electrician?

Yes. Any security system that connects to 240V power, such as CCTV, hardwired alarms, or video intercoms, must be installed by a licensed electrician. In Victoria, these systems must comply with AS/NZS 3000 and ensure proper circuit protection, cable segregation, and IP-rated enclosures if exposed to the elements.

Security System Requirements

Security systems today include more than just cameras. There are sensors, alarms, intercoms, electric locks, and cloud-based hubs, all of which require reliable, standards and compliant electrical work.
In suburbs like Narre Warren North, Berwick, Devon Meadows, Clyde and beyond, homeowners are upgrading not just for safety but for peace of mind.

At Direct Point Electrical, we wire smart security systems that work quietly, reliably, and legally. We ensure all of standards are met and documented on a Certificate of Electrical Safety (COES).

What Counts as “Security Wiring”?

Security system wiring refers to any fixed, powered component that forms part of your surveillance, alarm, or entry system. These can include:

• CCTV systems (POE or DC-powered)
• Wired alarm panels and PIR sensors
• Doorbell intercoms
• Electronic deadbolts or strikes
• External motion lights with cameras
• Garage entry systems
• Gate controllers or swipe access systems

Whether you’re installing a DIY kit or an enterprise grade NVR, if it connects to the 230V supply or fixed cabling, you need a licensed electrician.

What We Wire (and Why It Matters)

1. CCTV Systems (Wired)

Hardwired CCTV cameras offer better reliability than WiFi options and are ideal for:

• Larger homes
• Long retention storage (via NVR)
• External monitoring
• Smart motion alerts

We handle:

• Low voltage DC power routing
• Conduit protection for exterior runs
• Power-over-Ethernet switch installations
• Surge protection on exterior lines

2. Wired Alarm Panels

Many security systems include fixed PIR sensors, panic buttons, and sirens wired back to a central panel.

We install:

• 12V or 24V DC power cabling from the switchboard
• Separate conduits or cable trays for signal vs power
• Isolation switches and battery backups
• Mounting, programming, and testing support

3. Video Doorbells & Intercoms

Popular brands like Ring, Arlo, and Hikvision offer Wi-Fi versions, but wired intercoms provide:

• Better video/audio quality
• Secure power supply
• Integration with electric gates or locks

We handle:

• Low-voltage transformer installs
• External conduit for front gate wiring
• IP-rated enclosures for outdoor stations
• Cabling through brickwork or render without damage

4. Electronic Locks & Garage Access

We provide safe, high-reliability wiring for:

• Strike plates
• Keypad locks
• Swipe card or fob entry
• Smart garage door controllers (wired or relay-based)

Many of these systems draw low voltage but must be wired to secure, isolated DC power, not shared points or multi-use plugs.

Do You Need a New Circuit?

Sometimes, yes. If you’re adding:

• Multiple cameras
• High-powered NVRs
• Integrated lighting
• Wireless hubs or control units

Then a dedicated 10A–16A circuit may be required to prevent overload and ensure separation from other household loads.

We can also combine this upgrade with a Switchboard Upgrade if your current board is full, outdated, or lacks RCDs.

What About Smart Integration?

We design wiring layouts to support:

• Google Home / Alexa control of alarms
• IFTTT automation (e.g. “If door opens, turn on porch light”)
• Push notifications to mobile
• Remote lock/unlock functions

Many smart systems still require fixed wiring at key points (e.g. chimes, transformers, or PoE switches), which must be installed by a licensed professional.

FAQs

Can I install my own wired security system?

No, not if it connects to mains power or includes fixed cabling. DIY installations are limited to plug-and-play wireless kits.

Do wireless systems need an electrician?

Not for setup, but if you’re powering them from wall-mounted transformers or hardwiring lights or alarms, yes.

Do I need a permit to wire a CCTV system?

No permit is needed, but all electrical work must be performed by a licensed electrician and comply with state law.

How long does security wiring take?

Most full-system installs (CCTV + intercom + sensors) take 1–2 days, depending on home layout and accessibility.

Is surge protection required?

Yes, for all outdoor components and PoE lines. We install surge arresters to protect your system from lightning or grid faults.

Final Thoughts

Security starts with strong wiring. Whether you’re monitoring your driveway, linking sensors to a smart lock, or securing your garage, it only works if the electrical foundation is solid.

Direct Point Electrical provides fully certified, standards-compliant security system wiring across Melbourne’s outer east. We wire homes for safety and peace of mind.
