Frequently Asked Questions

How is it powered and charged?

It uses a removable, rechargeable lithium-ion pack (≈9,540 mAh). Pop it out to charge via micro-USB; typical life can reach months between charges, depending on activity and settings.

Does it require existing doorbell wiring or a chime?

No wiring is required. It’s battery-powered and is designed to connect over Wi-Fi to the Alarm.com Smart Chime (ADC-W115C) for in-home chime sounds and a robust link.

We onboard it to your network (and Smart Chime) and can use WPS pairing when appropriate; the LED patterns indicate progress during setup.

How weather-resistant is it?

The housing is IP66 and rated for –4° to 122 °F operation. We still recommend a vertical, shaded mounting spot for longevity and image quality.
