Choosing a smart lock with childproof mode means checking more than how many ways it can open. The key distinction is what the indoor safety setting actually restricts, and whether household members can still exit quickly in an emergency. I rank the Bestkid YL-MD11 with Inside Unlock Code first for its separate indoor code, the Eseesmart MD12 for families who want a camera and doorbell built into the lock, and the Anweller MD11 for a simpler sensor-equipped setup.

These picks make different compromises. Camera models add doorstep visibility but also depend on 2.4 GHz Wi-Fi and bring more components to install. The Bestkid inside-code model puts its child-safety control at the center, while the other locks rely on child-safety modes whose exact behavior buyers should confirm before enabling. I compare them by the usefulness of their indoor restriction, backup access, door-status monitoring, and practical tradeoffs—not by feature count alone.

More Details on Our Top Picks
Bestkid Child Safety Smart Deadbolt with Inside Unlock Code
This is my first choice when the goal is a clearly defined indoor restriction rather than a camera or the longest feature list. Its separate inside unlock code gives the childproof premise a concrete mechanism: opening from indoors requires an additional credential. Guardian Mode, entry and exit logs, and phone alerts add oversight, while fingerprint, PIN, RFID, app, and key access give adults several ways to enter.
Compared with the Bestkid YL-MD11 that simply lists a child safety mode, this model describes the indoor-code requirement more explicitly. That clarity helps with choosing, but it also makes safe configuration especially important: a lock that restricts interior unlocking may slow an adult’s exit. I would check the manufacturer’s instructions and local fire and building rules before turning on Guardian Mode, and I would make sure household members know the override procedure.
The door sensor reports whether the door is locked, unlocked, or ajar, which is useful if a child leaves the door open or the deadbolt has not engaged. The 10,000 mAh battery is stated to last up to 12 months, though actual duration depends on use and connectivity. Unlike the Eseesmart and Foxlock, it has no integrated camera, so it is a better fit for buyers who prioritize indoor control and status alerts over visitor video.
Pros:- Separate inside unlock code makes the indoor restriction more specific than a general child-safety-mode listing.
- Door sensor tracks locked, unlocked, or ajar status and can send phone alerts.
- Fingerprint, PIN, RFID, app, and mechanical-key access provide several entry options.
- 10,000 mAh battery is stated for up to 12 months of use.
Cons:- Guardian Mode may restrict a fast exit; verify emergency operation and local requirements before enabling it.
- Remote controls and alerts require the app and Wi-Fi.
- No built-in camera or video doorbell for monitoring visitors.
Best for: Households that want an explicit separate code for unlocking from inside, plus door-status alerts and multiple adult access methods.
Not ideal for: Buyers who need a simple interior thumb-turn or who cannot confirm that Guardian Mode permits a safe, code-compliant emergency exit.
- Brand and model:Bestkid YL-MD11
- Lock type:Biometric smart deadbolt
- Access methods:App, fingerprint, PIN, RFID card, and key
- Child-safety detail:Separate code required to unlock from inside; Guardian Mode
- Battery:10,000 mAh; stated up to 12 months
- Door sensor:Tracks locked, unlocked, or ajar status; app alerts
- Installation fit:Retrofit; standard US doors with 2-1/8-inch cross bore
- Included backup access:Two keys and two IC cards
Our verdict“I rank this first for its clearly described inside-code restriction, provided the household verifies a safe exit procedure before using Guardian Mode.”
Eseesmart MD12 Smart Lock with Camera, Child Safety Mode, and WiFi Door Sensor
The Eseesmart MD12 combines child-focused controls with the broadest doorstep-monitoring package in this group: a 2K camera, video doorbell, night vision, and two-way audio. That makes it more than a deadbolt for families who want to see and speak with visitors from the app. Its dedicated Childproof Mode and Child Lock Passcode add a stated layer of indoor control, while the sensor supports auto-locking and open-door alerts.
Against the Bestkid inside-code model, Eseesmart trades a more explicitly described interior-code requirement for stronger visitor visibility. The product description does not spell out the precise behavior of its Childproof Mode as clearly as Bestkid’s separate-code mechanism, so buyers should confirm exactly what is restricted and how an adult exits. It is also a busier choice than Anweller: the camera and doorbell add functions, but a household that only wants a basic child-safety lock may not need them.
Entry options include fingerprint, password, RFID, app, Wi-Fi, Bluetooth, and a mechanical key. The rechargeable 10,000 mAh battery and included sensor support a connected setup without relying on the camera alone for door status. A notable limitation is 2.4 GHz Wi-Fi only; a 5 GHz-only network will not meet the stated requirement. The product description also provides a 12-month warranty, but does not establish how long the battery lasts between charges.
Pros:- Integrated 2K camera, night vision, and two-way audio support doorstep monitoring.
- Dedicated Childproof Mode and Child Lock Passcode are aimed at family use.
- Door sensor supports auto-locking and open-door alerts.
- Fingerprint, password, RFID, app, Bluetooth, Wi-Fi, and key access offer flexibility.
Cons:- Requires a 2.4 GHz Wi-Fi network; 5 GHz support is not specified.
- Exact indoor restriction and adult exit behavior should be confirmed before enabling childproof controls.
- Battery runtime between charges is not stated in the supplied specifications.
Best for: Families who want a child-safety mode alongside a built-in camera, video doorbell, two-way audio, and door alerts.
Not ideal for: Buyers seeking a simple lock, a confirmed 5 GHz connection, or a child restriction whose indoor operation is fully specified in the product details.
- Brand and model:Eseesmart MD12
- Camera:2K with night vision
- Audio:Two-way audio
- Child controls:Childproof Mode and Child Lock Passcode
- Connectivity:2.4 GHz Wi-Fi and Bluetooth
- Access methods:Fingerprint, password, RFID, app, Bluetooth, Wi-Fi, and mechanical key
- Battery:10,000 mAh rechargeable Li-ion; USB-C
- Included sensor:Smart door sensor for auto-lock and door alerts
- Warranty:12 months
Our verdict“I recommend Eseesmart for families who value camera and doorbell features as much as childproof controls, but not for buyers who want the simplest lock.”
Anweller MD11 Smart Deadbolt Lock with Fingerprint and Wi-Fi
Anweller is the restrained choice in this roundup: it pairs a child-safety lock with a magnetic door sensor, auto-lock support, and open-door alerts, without adding a camera. For a household that wants to know whether the entry has closed and locked, that is a more focused package than the Eseesmart or Foxlock MD12. The product also lists ANSI/BHMA Grade 2, a 10,000 mAh rechargeable battery, and mechanical keys for backup access.
Its sensor-based approach is useful, but the description gives less detail about exactly how the child-safety lock changes indoor unlocking than Bestkid’s separate-code model. I would treat the mode as a feature to investigate, not as a guaranteed childproof outcome. Ask what action is blocked, whether a physical inside control remains available, and what happens if the battery or network fails.
Compared with Bestkid’s camera-free inside-code pick, Anweller provides a more conventional mix of fingerprint, RFID, app, and key access, but no stated indoor unlock code. Its built-in Wi-Fi means there is no separate bridge listed, though it supports 2.4 GHz only. The stated six-month average battery life is shorter than Bestkid’s up-to-12-month claim. Buyers who want fewer connected features may prefer its simpler setup; those who need precise indoor restriction details should favor Bestkid.
Pros:- Magnetic sensor supports auto-locking and alerts when the door is open.
- Fingerprint, RFID card, app, and mechanical-key access cover common entry needs.
- Built-in Wi-Fi allows remote app control without a listed extra bridge.
- 10,000 mAh rechargeable battery and two mechanical keys provide backup options.
Cons:- Child-safety mode behavior and emergency exit procedure are not described in detail.
- Battery life is listed as a six-month average.
- Wi-Fi is specified for 2.4 GHz only.
Best for: Buyers who want a child-safety feature, door sensor, auto-lock, and remote app access without an integrated camera.
Not ideal for: Households that need an explicitly documented separate interior code, camera monitoring, or a longer stated battery interval.
- Brand and model:Anweller MD11
- Access methods:Fingerprint, RFID card, app, and mechanical key
- Child-safety feature:Child-safety lock; exact indoor behavior should be confirmed
- Connectivity:Built-in 2.4 GHz Wi-Fi
- Battery:10,000 mAh rechargeable Li-ion; six-month average listed
- Door sensor:Magnetic sensor with auto-lock and open-door alerts
- Security grade:ANSI/BHMA Grade 2
- Dimensions and weight:6 × 2.9 × 1.1 inches; 2.9 pounds
- Warranty:12 months
Our verdict“I would choose Anweller over the camera locks for a focused sensor-and-auto-lock setup, but choose Bestkid when a defined inside-code restriction matters more.”
Foxlock MD12 Smart Deadbolt Lock with Camera and Child Safety Mode
Foxlock belongs in the same camera-equipped tier as Eseesmart, but its description adds practical installation and durability details: DIY setup with a screwdriver, IP54 water resistance, and an ANSI/BHMA Grade 2 rating. The MD12 also includes a 2K camera with a 160-degree lens, night vision, two-way audio, childproof mode, and a sensor for auto-locking and open-door alerts. For buyers who want one package to cover entry, video, and door status, it is feature-rich.
Compared with Eseesmart, Foxlock gives a stated lens angle, water-resistance rating, and emergency USB power support. Eseesmart, by contrast, calls out a Child Lock Passcode, while Foxlock’s description does not explain the exact mechanics of its child safety mode. That distinction matters more than the shared camera resolution: if restricting indoor unlocking is your main reason for shopping, the Bestkid inside-code lock remains the more explicit choice.
Foxlock lists fingerprint, keypad, app, Wi-Fi, and physical-key entry, plus four RFID cards in the included items. Its rechargeable 10,000 mAh battery has emergency USB power support, but no runtime is specified. The lock fits most standard US doors according to the description, yet buyers should check dimensions and existing hardware before ordering. As with the other camera lock, remote functions require 2.4 GHz Wi-Fi; IP54 also does not make it a fit for every exposed exterior location.
Pros:- 2K camera, wide-angle lens, night vision, and two-way audio add visitor monitoring.
- Childproof mode and door sensor support family-focused access and door alerts.
- Emergency USB power and two mechanical keys provide backup options.
- DIY installation, ANSI/BHMA Grade 2 rating, and IP54 water resistance are specified.
Cons:- Child-safety mode behavior is not described as specifically as Bestkid’s separate inside code.
- Requires 2.4 GHz Wi-Fi for remote features.
- Battery runtime is not stated, and IP54 may not suit highly exposed outdoor conditions.
Best for: DIY-minded households that want a child-safety mode, video doorbell functions, door alerts, and emergency USB power in one lock.
Not ideal for: Buyers who need a fully detailed indoor restriction, a stated battery runtime, or a lock for a highly exposed entryway.
- Brand and model:Foxlock MD12
- Camera and lens:2K HD; 160-degree wide-angle lens; night vision
- Audio:Two-way audio
- Child and door features:Childproof mode, door sensor, auto-lock, and open-door alerts
- Connectivity:Built-in 2.4 GHz Wi-Fi; no hub required
- Access methods:App, fingerprint, keypad code, Wi-Fi remote, and physical key
- Battery and backup power:10,000 mAh rechargeable Li-ion; emergency USB power support
- Installation and warranty:DIY installation; 12 months
Our verdict“Foxlock is my camera-focused DIY pick, while Bestkid remains the stronger choice when a clearly described interior unlocking restriction is the priority.”
Bestkid Keyless Entry Smart Deadbolt with Child Safety Mode
This Bestkid model is a good match for households that want several ways to manage who can enter: fingerprint, PIN, RFID, Bluetooth app, Wi-Fi remote access, and two emergency keys. Its child safety mode restricts indoor unlocking, while the app handles permissions, unlock records, notifications, and auto-lock. With capacity for 100 fingerprints, 20 PIN codes, and 100 RFID cards, it suits a busy household or a home with frequent visitors better than a pared-back keypad lock.
Compared with the Bestkid inside-code model, this one offers more precise credential-capacity details but does not describe a separate code required from indoors. That makes it less compelling for buyers whose first concern is preventing a child from operating the interior release. Its 5,000 mAh battery is rated for up to six months per charge, shorter than the other Bestkid’s stated up-to-12-month battery claim and Anweller’s 10,000 mAh capacity.
The lock supports USB-C charging, low-battery reminders, emergency Type-C power, and mechanical keys, giving owners several ways to deal with a depleted battery. It requires initial calibration during installation, and the six-month warranty is shorter than the 12-month coverage listed for Eseesmart, Anweller, and Foxlock. I would place it below those options for long-term reassurance, but its broad credential management can make sense when the household values flexible access more than a camera or explicitly described inside code.
Pros:- Supports fingerprint, PIN, RFID, Bluetooth app, Wi-Fi remote, and mechanical-key access.
- App provides permissions, unlock records, notifications, and auto-lock controls.
- Capacity for 100 fingerprints, 20 PIN codes, and 100 RFID cards accommodates multiple users.
- USB-C charging, low-battery reminders, emergency power, and two keys offer backup routes.
Cons:- Battery is rated for up to six months per charge.
- Six-month warranty is shorter than the 12-month coverage listed for several competing picks.
- Initial calibration is required, and indoor restriction details are less specific than the inside-code model.
Best for: Households managing many fingerprints, PINs, or RFID cards that also want app permissions and a child safety mode.
Not ideal for: Buyers prioritizing a separately described interior unlock code, longer stated battery life, or a longer warranty.
- Brand and model:Bestkid YL-MD11
- Access methods:Fingerprint, PIN, RFID, Bluetooth app, Wi-Fi remote, and emergency key
- Child-safety feature:Child safety mode restricting indoor unlocking
- Credential capacity:100 fingerprints, 20 PIN codes, and 100 RFID cards
- Battery:5,000 mAh; up to six months per charge
- Charging:USB Type-C, 5V/1A; approximately five hours
- Backup access:Two emergency keys and emergency Type-C power
- Operating temperature:-4°F to 113°F
- Warranty:Six months
Our verdict“I recommend this Bestkid for households that need flexible credential management, not for buyers who want the clearest indoor restriction or longest listed battery interval.”
How We Picked
I ranked these locks around the part of the brief that matters most: childproofing indoor access. A lock that lists a child safety mode is not automatically equivalent to one that requires an inside unlock code. I gave the Bestkid model with a separate inside code the leading role because its restriction is described most concretely, while also flagging that Guardian Mode could affect a quick exit.
Next, I compared the support features that affect day-to-day household use: door sensors, auto-lock behavior, access methods, backup keys, battery details, and remote connectivity. Sensors can tell a household whether a door is ajar, while a camera can add visitor visibility; neither replaces a dependable mechanical exit plan. I treated those features as useful distinctions rather than proof of a lock’s child-safety performance.
Finally, I considered the tradeoffs in setup and ownership. The Eseesmart and Foxlock add 2K video and two-way audio, but their 2.4 GHz Wi-Fi requirement and extra camera functions may not suit every entryway. Anweller is more straightforward but lists a six-month battery average. Bestkid’s standard child-safety model offers broad keyless access, yet its shorter stated battery life and six-month warranty count against it. Product descriptions do not settle how a lock behaves during power, network, or emergency conditions, so I recommend verifying those details and checking applicable fire and building requirements before enabling an interior restriction.

Factors to Consider When Choosing Smart Locks With Childproof Mode
Before choosing, I would separate the phrase “childproof mode” from the lock’s other smart features. The central question is what the lock prevents a child from doing and how an adult can still leave quickly. A camera, fingerprint reader, or auto-lock may be useful, but none answers that question on its own.Find out what the indoor mode actually blocks
Product labels vary. Bestkid’s inside-code model specifically says a separate code is required to unlock from indoors, while the other listings use terms such as child safety mode or childproof mode. I would check the manual for the exact behavior: whether the mode disables an interior control, requires a PIN, or changes only app settings. Confirm the adult override method and test it with the door open before relying on the mode. A restriction that creates a slow or unclear exit is not a sensible trade for convenience.
Treat emergency exit and code compliance as part of the decision
Any lock that adds a code or restriction to indoor unlocking deserves extra care. Ask the manufacturer how the lock behaves during a dead battery, lost network connection, or an emergency, and check local fire and building requirements. Keep mechanical keys accessible to responsible adults, and make sure other household members understand the exit procedure. A feature described as childproof should not be assumed to replace supervision or an approved emergency egress route.
Choose sensors and cameras for different jobs
A door sensor answers questions such as whether the door is ajar or whether auto-lock has engaged. That can help a household catch an open entry, but it does not show who is outside. Eseesmart and Foxlock add cameras, night vision, and two-way audio for visitor monitoring; Anweller and the Bestkid picks concentrate on lock access and status. I would pay for camera features only if seeing or speaking with visitors is a real household need.
Match access methods to the people using the door
Fingerprints and PINs can reduce reliance on phones, while RFID cards and mechanical keys provide alternatives for users who do not want biometric access. App and remote unlocking are useful when granting access from elsewhere, but they add a network dependency. The two Bestkid models serve different needs: one emphasizes a separate indoor code, and the other lists large credential capacities. Compare those priorities instead of treating their shared model name as proof that their child controls work alike.
Check Wi-Fi, battery, installation, and the actual door
Eseesmart, Foxlock, and Anweller specify 2.4 GHz Wi-Fi; verify that your router and the lock’s installation location can support a reliable connection. Battery claims are not directly equivalent: one Bestkid lists up to 12 months, Anweller gives a six-month average, and the other Bestkid lists up to six months per charge, while the camera models do not state runtime in the supplied details. Check cross-bore and door compatibility, available clearance, charging access, and backup-key plans before buying. Installation directions and listed fit do not substitute for measuring your own door.
Frequently Asked Questions
What does childproof mode mean on a smart lock?
The phrase can refer to different indoor restrictions, so I would not assume every lock behaves the same way. The Bestkid inside-code model explicitly requires a separate code for indoor unlocking; the other listings describe a child safety or childproof mode without the same level of detail. Read the operating instructions to learn what the mode blocks, how an adult exits, and what happens if power or connectivity fails.
Which option gives the clearest description of indoor child control?
The Bestkid Child Safety Smart Deadbolt with Inside Unlock Code is the clearest in this lineup because its description states that a separate code is needed to unlock from inside. That does not by itself prove it is right for every home: check the Guardian Mode behavior, emergency override, and applicable fire or building rules before enabling the restriction.
Are the camera-equipped locks better for family safety?
Eseesmart and Foxlock add a camera, two-way audio, night vision, and door-sensor features, which can help a household check visitors and monitor the entry. Those functions do not replace a properly understood indoor exit method or close supervision. For a clearly described interior code, the Bestkid inside-code model is the more direct match; choose a camera model when doorstep visibility is also a priority.
Can these locks work if Wi-Fi is unavailable?
Connectivity affects remote app functions and alerts, but several locks also list local entry methods such as fingerprint, PIN, RFID, or a mechanical key. The supplied descriptions do not fully explain every model’s offline behavior, so I would verify which features remain available without Wi-Fi and whether the child-safety mode changes. Keep backup keys and follow the manufacturer’s battery and emergency-power instructions.
What should I check before installing one on a family door?
Confirm the lock fits the door’s bore, thickness, backset, and existing hardware, then review the installation and calibration steps. Before using a child restriction, test adult exit and backup access with the door open, and check local egress requirements. Also verify Wi-Fi frequency, battery charging access, sensor placement, and the household’s plan for mechanical keys or emergency power.
Conclusion
For the most clearly described indoor restriction, I would start with the Bestkid Child Safety Smart Deadbolt with Inside Unlock Code, while confirming that Guardian Mode permits a safe, compliant exit. Choose Eseesmart MD12 if you want a camera and video-doorbell functions alongside child controls, or Foxlock MD12 if DIY installation and emergency USB power are priorities. The Anweller MD11 suits buyers who prefer a sensor-and-auto-lock setup without video. Pick the other Bestkid YL-MD11 for managing many credentials, accepting its shorter stated battery interval and warranty. In every case, I would verify the exact indoor behavior and door fit before purchase.
