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.

Best door handle and lock out there.. except notifications
This is one of the best ones out there. Ive purchased so many cheap ones and its worth it to buy one good one instead of numerous bad ones. This one got one is the best only issue is it needs to come with a handle to put on the door or something in case you need to grab it there is nothing to grab or get a spring loaded door shutter. Thanks !!

Smart lock with camera
I put this smart lock on my mom’s front door during the holiday time so she doesn’t have to worry about forgetting her keys. The lock feels solid in the hand, and the outside part looks neat on her door. I was able to install it myself with a simple screwdriver, and the size fit her old deadbolt spot without much trouble. Now my mom uses her fingerprint to open the door, and the sensor usually recognizes her pretty fast, though once in a while she needs to try a second time. I added the lock to the app on my phone, so if I get to her house and she is not home yet, I can tap on the app to unlock the door for myself or other family members. The small camera and doorbell let us see who is standing there, even at night, which makes both of us feel safer.

Peace of mind when I’m home alone
This lock helps with that in a way that feels everyday and natural. I like being able to see who is at the door before I decide to respond. Sometimes it’s a delivery, sometimes it’s a neighbor, and sometimes it’s someone I do not want to answer. Having the live video and two-way talk means I can handle it without opening the door or guessing. Unlocking choices matter more than I thought. Fingerprint entry is convenient, but I also keep the keypad option in mind for situations where I want a different method. The app control is useful when I’m not right next to the entry, and the indoor monitor makes checking the door feel simple and immediate. I also like that it’s one integrated setup, so I’m not managing multiple devices with different quirks.

Makes deliveries easier to manage
One of the biggest improvements for me has been handling deliveries. When someone arrives at the door, I can see what’s happening without opening it or guessing based on a knock. Being able to speak through the doorbell has been useful for quick instructions or acknowledgments, especially when timing matters.Unlocking options give me flexibility depending on the situation. If I’m nearby, fingerprint entry is quick. If I’m not close to the door, app control lets me handle things without moving across the house. The indoor display has become part of my routine, letting me check the door at a glance while staying focused on other tasks. It feels less disruptive than phone alerts and more natural in daily life. The entire setup gives me a sense that my front door is responsive and manageable instead of something that demands immediate attention every time there’s activity.

Useful for working from home
While working from home, interruptions at the door can break focus. This lock has helped me manage that better. When someone arrives, I can quickly check the indoor display and see who it is without standing up or pausing my work. If needed, I can speak through the doorbell and handle things without opening the door. Unlocking options give me flexibility depending on where I am in the house. Fingerprint access works well when I’m heading out between meetings, and app control is useful when I’m not nearby. The system feels supportive of a busy schedule rather than disruptive.

Easy entry for busy hands and kids
My day is usually a juggling act—bags, groceries, and somebody asking a question while I’m trying to unlock the door. This lock has made that moment smoother. Fingerprint entry is quick, and the keypad option is there for anyone who prefers typing a code. I also like having a backup key in the mix, just for peace of mind. What really makes it feel “thought through” is the indoor display. If I’m in the kitchen and the doorbell goes off, I can peek without stopping everything. It’s simple to check who is outside, and the two-way talk works well when I need to answer without opening the door. The chime is loud enough to catch my attention, even from another room.

Remote checks make my trips less stressful
I travel on and off, and I wanted a way to keep an eye on my entry without bothering neighbors. With this lock, I can check the live view and see what’s going on at the door, even when I’m not home. If someone shows up, I can talk through the doorbell and handle it without making it a whole production. The multiple ways to unlock have been handy for me too. Sometimes I use the fingerprint, sometimes the code, and sometimes I use the app if I’m coming in with luggage. It’s also nice knowing family can use what feels natural to them instead of everyone learning one method. The camera view in low light has been reliable, and the overall system feels like it was built to be a single, complete front-door setup rather than separate pieces glued together.

Helpful when hands are full
Coming home with bags, boxes, or other items used to be an awkward moment at my door. With this lock, that part of the day feels smoother. Fingerprint unlocking means I don’t have to dig around or set things down. It’s quick and reliable, which makes a real difference during busy moments. The doorbell camera has also changed how I handle interruptions. If someone shows up while I’m in the middle of something, I can check the indoor display and decide what to do without stopping everything. Sometimes I answer through the speaker, sometimes I wait. That choice feels empowering rather than stressful.
