A doorbell is a simple but effective luxury of everyday life. It’s more convenient than knocking, gets your attention quickly, and makes sure you never miss an important visitor.
Today, you have the option of smart doorbells. Smart doorbells elevate traditional doorbells with added security features that allow you to see who’s at your door, speak to them, and receive alerts about activity on your property. No more surprises!
For an additional layer of security, you can integrate your CCTV system with your smart doorbell too. Whether you want to keep an eye out for deliveries or never miss a guest, a smart doorbell gives you peace of mind about your property.

We’re experienced in installing traditional wired and smart doorbells, and if you’re looking for a complete security system integration, we can handle that too.

Wired doorbells are not complicated; their components consist of a circuit that has a push-button, chime, and low-voltage AC transformer. The doorbell transformer steps down your home’s high-voltage to a level that is manageable for the small device.
Most smart doorbell systems operate at a higher voltage range than traditional doorbells and may require a transformer upgrade.
Dealing with the transformer and hardwiring your doorbell system still requires an electrician to do it safely. There are also different procedures for existing doorbell systems and new installations.
If there is existing wiring in place, either from a previous doorbell or created during construction, the process is straightforward.
Your switchboard will already have a corresponding circuit for your front door, which will be switched off while we work.
Our job then is to connect the wall wires to the terminal screws and mount the doorbell to its dedicated bracket. After that, we’ll restore power and test the device.
If it’s a smart doorbell camera, you’ll need to download the respective mobile app, and we’ll help you configure your device, connect to your Wi-Fi network, and sync with any smart home systems in place.
If there isn’t an existing system, then there are a few extra steps to take. A new system installation will involve:
And to wrap things up, we’ll test the hardware and help you configure your smart doorbell if necessary.
For greater surveillance capabilities and convenience, you can connect your video doorbell to an existing home CCTV system. By combining your two systems, you can:

Yes, you will need an electrician to install a wired doorbell in your home, regardless of whether you have an existing system or not. Because wired doorbells are connected to your home’s electrical system, a licensed electrician needs to carry out the process. An electrician may be needed for:
A standard doorbell installation will take approximately 20-45 minutes. However, if a new transformer or wiring upgrade is required, the installation process may take up to 1-2 hours. Any system upgrades, wire repair or new installations will add to installation time frames.
If your internet goes down, your smart doorbell will not be able to carry out key security features such as:
However, most smart doorbell models can still operate as a standard doorbell if they are hardwired into your home’s electrical system.
The cost of a smart doorbell installation will depend on the doorbell model you have chosen and whether you have pre-existing wiring or require an upgrade to your system. Replacing an old hardwire device may require a transformer upgrade to accommodate the smart doorbell’s required voltage. On average, a smart doorbell installation costs between $150 and $650.
Typically, if you are a homeowner, you don’t need any special permissions to install a camera doorbell on your property. If you are renting or living in an apartment complex, you will need to seek permission from your landlord or building’s Strata.
