A door lock with camera combines a motorized lock with a built-in camera so you can see, speak to, and verify visitors before remotely unlocking the door.
A door lock with camera isn’t just a smart lock with a peephole upgrade. It’s a 3-in-1 device that merges a smart deadbolt, a video doorbell, and app-connected access control into one unit mounted on a single door. Instead of juggling a separate lock and doorbell, you get one device that handles entry, identification, and conversation.
The camera activates on motion, a doorbell press, or live app access, then sends alerts to your phone. You can check who’s there, talk through two-way audio, and unlock the door if you want to let them in—all from the companion app. It’s the difference between knowing someone knocked and knowing exactly who is standing on your porch.
How a Door Lock with Camera Works
The lock’s electronic mechanism controls the deadbolt or latch, while the camera system handles video, motion detection, and two-way audio. The two parts run through the same app, so a single interface manages both locking and viewing.
Most models unlock through several methods—fingerprint, PIN keypad, smartphone app, voice commands, NFC or RFID cards, and a physical key. Higher-end models add face recognition or palm scanning. Connectivity varies by model: Wi-Fi enables remote access from anywhere, while Bluetooth works only within range unless paired with a bridge or hub.
Popular Models and What They Offer
Several manufacturers make door locks with cameras, and the feature set differs meaningfully between them. The eufy Video Smart Lock S330 packages a 2K camera, fingerprint reader, and doorbell into one unit, with a 10,000 mAh rechargeable battery and expandable storage up to 128 GB microSD. It’s marketed as having no monthly fee.
The Lockly Vision streams live video through the Lockly Home App so you can verify identities and remotely unlock. TP-Link’s Smart Video Door Lock integrates a doorbell, 2K ultra-wide camera, and lock with auto-lock, alarms, and notifications. The myQ Secure View offers a 3-in-1 design with 2K video and a 150-degree wide-angle lens.

Battery Life, Storage, and Subscription Reality
Camera locks consume noticeably more power than standard smart locks because video recording and streaming drain batteries fast. The eufy S330 ships with a 10,000 mAh rechargeable battery to handle the load, but expect to recharge more often than you would with a simple smart lock. Battery management is the main maintenance task with these devices.
Video storage varies. Some models, like the eufy S330, use a microSD card (expandable to 128 GB) with no subscription. Others may require a cloud plan for video history. The “no monthly fee” claim is product-specific—it never applies across the whole category. Check the storage method and any subscription requirement before buying, because a $0 fee lock and a $10-per-month lock are different long-term purchases.
The camera’s motion detection and field of view matter too. The eufy S330’s dual motion detection reaches up to 17 feet, while the myQ Secure View uses a 150-degree lens. Wider coverage means fewer blind spots at your entryway.

Is a Video Smart Lock Right for You?
A door lock with camera makes sense when visitor identification matters as much as remote locking. If you want to confirm a delivery driver’s identity before buzzing them in, or check who’s at the door while you’re away, the camera is the point. If you only need remote locking, a standard smart lock costs less and uses less power.
Installation matters too. These are heavier units than standard deadbolts, and they need a solid door and proper alignment. Most replace an existing deadbolt with basic tools, but the added camera housing means more surface area on the door interior.
Also note that a door lock with camera is not the same as a separate doorbell camera. A doorbell camera watches your porch but doesn’t control entry. A camera lock does both—one device, one app, one install point.
FAQs
Do camera locks require a monthly subscription?
Not always. Some brands like eufy offer local storage on a microSD card with no recurring fee. Other manufacturers use cloud storage that requires a paid plan for video history. Always confirm the storage method and subscription terms for the specific model you’re considering before purchase.
Can I unlock a camera lock with my phone?
Yes. Most camera locks connect to a companion app that lets you unlock, lock, view live video, and talk to visitors from anywhere with an internet connection. The exact app depends on the brand—eufy uses the eufy Security app, while Lockly uses the Lockly Home App.
How long does the battery last on a video smart lock?
Battery life varies widely by model and usage. The eufy S330 includes a large 10,000 mAh rechargeable battery to support its camera and lock functions. Video recording and live streaming drain power far faster than simple lock mechanisms, so plan for more frequent recharging than standard smart locks.
