- Optional: Voltage Meter: If you’re unsure about the power supply from your existing transformer, a voltage meter can confirm it’s within the acceptable range (typically 8-24V AC for wired Arlo doorbells).
Understanding Your Existing Doorbell System
The process of installing an Arlo doorbell can differ depending on whether you are replacing an existing wired doorbell, installing it in a location without a prior doorbell, or opting for a wireless model.
Wired Doorbell Replacement
If you have an existing wired doorbell, the Arlo doorbell is designed to integrate with your current chime system. You’ll need to identify the transformer and the existing wiring.
- Locate the Transformer: The doorbell transformer is usually found in your electrical panel, near your furnace, or in your garage. It converts your home’s high-voltage AC power to the low-voltage AC power required by your doorbell. Ensure it outputs between 8-24V AC. If your transformer is insufficient, you may need to replace it, which is a more advanced electrical task.
- Identify Existing Chime: Most wired doorbells connect to an indoor chime unit. The Arlo doorbell typically works with mechanical chimes and some electronic ones. Consult your Arlo manual for specific chime compatibility.
- Disconnect Power: Crucially, before touching any wires, turn off the power to your doorbell circuit at your breaker box. This is a non-negotiable safety step.
No Existing Doorbell or Wireless Installation
If you don’t have an existing wired doorbell, you have two primary options:
- Hardwiring: You will need to run new low-voltage wiring from a compatible transformer (you may need to install one) to the doorbell location. This is a more involved process and might require professional assistance if you are not comfortable with electrical wiring.
- Wireless Models: Arlo offers battery-powered video doorbells. These are the easiest to install as they don’t require any wiring. You simply mount them and connect them to your Wi-Fi via the Arlo app. Ensure the battery is fully charged before installation.
