Meet Smrtiplx

Smrtiplx smart lock is the 4-in-1 smart home solution that combines a door lock, video doorbell, outdoor camera, and indoor display monitor—all in one sleek device. It’s designed for real families who care about security, want easy control from anywhere, and don’t want to break the bank.

Why We Built Smrtiplx

One ordinary afternoon, our founder Joe was working from home while looking after his daughter. He stepped outside to take a quick call, and the door accidentally shut behind him. His daughter, remembering Joe’s advice never to open the door unless she’s absolutely sure who’s there, refused to unlock it—even though Joe was right outside. She couldn’t see or hear who was at the door—and that moment sparked an idea.

What if there were a smarter, safer way to know who’s really at your door—without guessing or yelling through it?

4-in-1 Advanced Security System: Experience all-around protection with a single device. This smart lock combines fast fingerprint recognition (100 fingerprint capacity), a built-in HD camera with auto night vision, and a video doorbell. Monitor your doorstep clearly day and night—always know who’s there
6 Flexible Unlock Methods: Unlock your door your way. Use your fingerprint, enter a PIN, control remotely via app, use voice commands with Alexa or Google Assistant, key fobs, or a physical key. Convenience and security—always accessible
Smart Indoor Display for Instant Viewing: See who’s at the door in real-time—no phone needed. The user-friendly display offers instant visual confirmation, making it ideal for seniors and kids. Enhance home safety and give your family peace of mind
App Remote Control from Anywhere: Stay connected to your home no matter where you are. With built-in 2.4GHz Wi-Fi, use the smartphone to lock/unlock the door, view live video, and talk to visitors directly from your smartphone. Perfect for busy lifestyles. If your smart door lock is installed too far from the router or blocked by multiple walls, it is recommended to purchase a Wi-Fi extender.

Easy Installation & Reliable Support: Fits most standard U.S. and Canadian wooden doors. Install in just 15 minutes—no drilling needed. Backed by our 24/7 customer service and a 12-month warranty, enjoy smart security without the hassle
