A Professional Guide to Solving Arlo Wiring Problems
Installing a wired Arlo camera or video doorbell can provide a constant, reliable stream of security footage without the need to ever change batteries. However, this reliability depends entirely on a correct and stable wiring installation. If your device is not powering on, frequently disconnects, or is showing a low power warning, it's time to troubleshoot the wiring.
Safety First: Before you begin any work, you must turn off the power to your doorbell or camera circuit from your main circuit breaker. Working with electricity is dangerous and should be done with the utmost care.
## Issue 1: The Device Will Not Power On
This is the most common issue after a new installation and is almost always related to insufficient power.
### Check Your Transformer
The transformer is a small box, usually located in a cupboard, attic, or near your main electrical panel, that steps down your home's high voltage to a low voltage suitable for devices like doorbells.
- Voltage Requirements: Arlo wired doorbells require a transformer rated between 16-24V AC. Many older homes have transformers that are only 8-10V AC, which is not enough to power the doorbell's camera and Wi-Fi chip.
- How to Check: The voltage is usually printed on the transformer body. If it's below 16V AC, you will need to replace it with a compatible one. This is the number one solution for power-related issues.
### Secure Wire Connections
- At the Arlo Device: Ensure the wires are securely wrapped around the terminal screws on the back of the Arlo device and that the screws are tightened firmly. A loose connection here will prevent power from reaching the device.
- At the Chime Box: Check the connections inside your internal doorbell chime. Ensure all wires are secure and that no two wires are touching, which could cause a short circuit.
## Issue 2: Frequent Disconnections or "Low Power" Warnings
If your device works intermittently or the Arlo app is warning you about low power, it points to an unstable power supply.
### The Arlo Power Kit is Essential
For the Arlo Video Doorbell, the installation of the included Power Kit is mandatory.
- What it Does: This small component is installed inside your existing chime box. It regulates the power flow, ensuring the doorbell gets a consistent supply of energy without buzzing or damaging your chime.
- Correct Installation: Follow the Arlo app's instructions carefully. You typically connect the Power Kit wires to the "Front" and "Trans" (Transformer) terminals in your chime box. An incorrect installation will lead to power instability.
### Wire Gauge and Condition
- Old Wiring: The wiring itself can be a point of failure, especially in older homes. Look for any signs of fraying, corrosion, or damage along the wire's length.
- Thin Wires: Very thin wires can struggle to deliver adequate current over a long distance. While less common, this can contribute to power loss.
## Issue 3: The Existing Chime Does Not Ring
If the Arlo doorbell works but your internal chime is silent, the issue is almost always in the chime box wiring.
- Check Power Kit Connections: Re-verify that the Power Kit is installed exactly as shown in the manual.
- Chime Compatibility: Ensure your chime is compatible. The Arlo Video Doorbell works with standard mechanical and electronic chimes but may not work with intercom systems or DC-powered chimes.
- Bypass Mode: If you don't have a chime or don't want to use it, you must still install the Power Kit by connecting it directly to the wires coming from your transformer. This is often called "bypass mode."
By methodically checking your transformer's voltage, ensuring every connection is secure, and correctly installing the Power Kit, you can resolve nearly all wiring-related problems with your Arlo devices. If you are not comfortable working with electrical wiring, please hire a qualified professional.
