A video doorbell with an HD camera, two-way audio, and an enhanced motion detector sends real-time alerts straight to your phone. Even at night, the image remains sharp thanks to high-contrast night vision. Connects to existing wiring, and with a Ring Home subscription, recordings can be stored for up to 180 days. Compatible with Alexa: just say “Alexa, talk to the front door” – and you’re instantly connected to your guest!
