Knowing who is at your door — before you open it — has quietly become one of the most valuable features in home security. A smart lock with video call and smart notifications turns your front door into a two-way window on the world: you see the visitor, speak to them, and decide whether to let them in, all from your phone and all from anywhere. This guide explains how video calling and real-time alerts work, the everyday situations they transform, and how they raise your awareness and security without adding complexity.
What is a smart lock with video call?
A smart lock with video call combines a secure door lock with a built-in camera and intercom. When someone approaches or presses the bell, the lock streams live video to your phone and lets you talk through two-way audio, just like a video doorbell — except it is integrated with the lock itself, so you can also unlock the door remotely in the same app. On models like the premium Covlor® push-pull locks, the camera sits in the exterior panel, giving you a clear view of your doorstep day or night.
How video calling and notifications work together
The two features reinforce each other. A notification tells you something has happened — a visitor, a knock, motion at the door, or an unlock — and the video call lets you see and respond. When the doorbell rings, your phone shows a live call; you glance at who it is, speak if you want to, and either open the door with a tap or simply dismiss it. Because everything flows through one app, there is no juggling separate cameras and locks: awareness and action happen in the same place.
What video and notifications let you do
The practical payoff shows up in dozens of small moments. The table below pairs common situations with the alert you receive and the action you can take, so you can see exactly how the feature fits everyday life.
| Scenario | Alert you get | What you can do |
|---|---|---|
| Visitor rings | Video call to your phone | See & speak, unlock remotely |
| Delivery arrives | Snapshot + notification | Grant a one-time code |
| Someone loiters | Motion / tamper alert | View live, trigger alarm |
| Kids arrive home | Unlock notification | Confirm they are safe |
| You are away | Any entry logged | Check who & when |
See and speak to visitors from anywhere
The headline benefit is presence without proximity. Whether you are at work, travelling or simply upstairs, a visitor at your door reaches you instantly. You can accept a parcel by speaking to the courier and granting a one-time code, tell a salesperson you are not interested without opening the door, or greet a family member and let them in remotely. For anyone who works away from home or travels often, being able to answer the door from another city is a genuine upgrade in both convenience and control.
Improved home awareness and safety
Beyond answering the door, video and notifications sharpen your overall awareness. You know the moment your children arrive home from school, see when a delivery actually lands, and get alerted to motion or tampering at the entrance. If someone lingers at the door, you can view the live feed and decide how to respond, and a tamper alarm adds another layer. This constant, gentle stream of information means you are rarely surprised by what happens at your threshold — a quiet confidence that a plain lock could never provide.
Protecting deliveries and managing visitors
Parcel theft and missed deliveries are everyday frustrations that video calling helps solve. When a courier arrives, you can speak to them, watch the parcel being left, and even grant temporary access to a secure porch if you have one. For expected visitors — a plumber, a relative, a guest — you can confirm their identity on camera before issuing a code or unlocking remotely. The result is fewer missed deliveries, less doorstep uncertainty, and a record of who came to your door and when.
Notifications that keep you informed, not overwhelmed
Good smart locks let you tune notifications so they help rather than nag. You might choose to be alerted to every unlock while you are away but only to the doorbell when you are home, or to flag unknown activity more prominently than routine family entries. Each alert carries useful detail — who, what and when — and taps straight through to live video or the access log. Set up thoughtfully, notifications become a reliable briefing on your home’s front door rather than a stream of noise.
Privacy and secure storage
With a camera at the door, privacy matters, and quality systems are designed with it in mind. Video calls are encrypted in transit, access to the feed is tied to your secure account, and you control who in the household can view it. Footage and logs are protected behind your credentials, and biometric matching for the lock still happens on the device. Used sensibly — a strong account password, two-factor authentication and trusted users only — a smart lock with video call enhances security without compromising your family’s privacy.
Choosing a video-enabled smart lock
If video calling appeals to you, look for a lock with a clear camera, reliable two-way audio, good low-light performance and dependable notifications, backed by a solid app. A strong battery is important, since video draws more power than simple entry, and an all-metal body and tamper alarm round out the security. The premium end of the Covlor® range pairs these connected features with face, palm and fingerprint entry and a mechanical-key backup, so you gain awareness without giving up any of the everyday convenience.
Video lock vs a separate doorbell camera
Many homes already have a doorbell camera, so why choose a lock with video built in? The answer is integration. With a separate camera you see the visitor but still need another device, or a key, to let them in — two apps, two accounts, two things to maintain. A smart lock with video call unites seeing and acting in one place: you watch the live feed and unlock with the same tap, in the same app. It is tidier, faster and more reliable, and it removes the awkward gap between recognising a welcome visitor and actually opening the door for them.
There is also a security advantage to integration. Because the camera and lock share one system, the access log and the video record line up, so you can match an entry to the person who made it. That unified picture — who rang, who entered, and when — is far harder to piece together when your camera and lock come from different makers and live in different apps.
Getting the most from your video lock
A few simple steps make a video-enabled lock shine. Position matters little because the camera is built into the panel at the right height, but good Wi-Fi near the door keeps the stream smooth, so add a gateway or extender if the signal is weak. Set your notification preferences thoughtfully — prominent alerts for the doorbell and unknown activity, quieter ones for routine family entries — so the information helps rather than overwhelms. Make sure more than one adult in the household can receive calls and unlock remotely, and keep the battery charged, since video uses more power than simple entry. With these small habits, the feature becomes a dependable, everyday window on your doorstep.

Frequently Asked Questions
How does a smart lock with video call work?
A camera and intercom in the lock stream live video and two-way audio to your phone when someone is at the door, and you can unlock remotely from the same app.
Can I answer the door when I am not home?
Yes. As long as the lock has internet, you receive the video call anywhere, can speak to the visitor, and can grant access or a one-time code remotely.
Does video calling use a lot of battery?
Video draws more power than simple unlocking, so you may recharge a little more often. Low-battery warnings and USB-C backup keep you covered.
Is the video feed private and secure?
Yes. Feeds are encrypted and tied to your secure account. Use a strong password and two-factor authentication, and limit viewing to trusted household members.
Can more than one person get the video call?
Yes. You can add several trusted household members to the account so that a visitor’s call and notifications reach everyone who should respond. If one person is busy or out of signal, another can still see the visitor and unlock the door, so the front door is never left unanswered when someone is home or reachable.

A smart lock with video call and smart notifications gives you something a key never could: the power to see, speak to and admit visitors from anywhere, and to always know what is happening at your front door.
