SMRTIPLX S398 Video Smart Lock , 4-in-1 Camera + Video Doorbell + Fingerprint Keyless Door Lock + Indoor Display Monitor
This Video Smart Lock is designed for busy homeowners who want to keep an eye on package deliveries while at work. Instead of just a standard deadbolt, think of it as a home security camera and doorbell combined into one sleek lock.
The built-in HD camera with auto night vision lets you see who approaches your door, even in the dark. When a visitor rings, the indoor display shows them instantly–no need to grab your phone. The fingerprint sensor unlocks the door in under a second, perfect for when your hands are full with groceries. If a child comes home from school, you can unlock remotely via the app after confirming their identity on the live feed.
The two-way audio lets you tell a delivery driver to leave a package safely, and the motion alerts pop up before your neighbor even notices. It’s Alexa compatible, so you can lock the door with your voice while cooking dinner. With a durable 10,000mAh battery and weather-resistant build, this lock gives you peace of mind without constant maintenance.
