How it protects and simplifies your door duty

The doorbell continuously watches over your entryway, sending alerts when activity is detected. If someone passes by, lingers, or rings the bell, you’ll receive an alert on your phone and can review the real-time feed instantly. The AI detection minimizes nuisance alerts, so you only respond to genuine visitors. When you’re away, you can still verify who’s at the door and communicate via the built-in remote intercom.

Battery life and power convenience

The device features an 8000mAh battery designed for long operation without frequent charging. Choose between modes for balance between power and immediacy: Standard mode offers up to about six months of use on a single charge, while Real-time viewing mode reduces battery life to about three months for continuous live monitoring. A convenient Type-C port makes topping up the battery straightforward.

Storage, security, and data protection

Keep footage securely with both cloud and local storage options. The system employs secure encryption to protect your recordings and notifications, giving you peace of mind whether you’re at home or away.
