Best for
Single-bore doors needing integrated handles

Best for
Households wanting indoor countertop video viewing

Best for
Doors with existing video doorbells

The eufy Security Smart Lock FamiLock E34 is engineered specifically for homeowners who want cutting-edge palm vein recognition without turning their deadbolt into a video doorbell. By focusing strictly on physical access rather than streaming video, this model achieves impressive power efficiency. Its primary 10,000mAh rechargeable lithium cell provides up to 8 months of operation, supported by a built-in 750mAh non-removable emergency backup battery that keeps the lock functional during main pack swapping or unexpected drainage.

Equipped with sub-dermal biometric sensors, the lock achieves 99.9% recognition accuracy in approximately 0.6 seconds. Since all biometric templates are saved locally on the device, personal vascular data never leaves the premises. Built-in Wi-Fi allows direct out-of-the-box mobile management without requiring a proprietary bridge, making it simple to link access events alongside an existing eufy doorbell 4k installation inside the unified companion application.

Smart home integration is versatile on this deadbolt. It works with Apple Home, Google Home, Amazon Alexa, and Samsung SmartThings via Matter, making it a reliable eufy Matter smart lock Apple Home owners can adopt without compatibility hurdles. Installation follows standard North American door prep dimensions, requiring no drilling for standard exterior deadbolt cutouts.

• Dual battery system combining a 10,000mAh main rechargeable pack with a 750mAh internal backup cell
• Built-in Wi-Fi radio eliminating the need for standalone network bridges
• Matter protocol support across Apple Home, Alexa, Google Home, and SmartThings ecosystems
• Vascular scanning sensor achieving 99.9% accuracy with rapid 0.6-second door latching

Best for
Front doors wanting 2K camera monitoring

The eufy Security Video Smart Lock FamiLock merges two critical front porch security devices into a single exterior deadbolt assembly: a vascular recognition sensor and a high-definition 2K camera. Built with an f/1.8 aperture lens featuring High Dynamic Range (HDR), the optical sensor covers a wide angle of 150 degrees vertical, 150 degrees horizontal, and 180 degrees diagonal. This panoramic perspective allows homeowners to monitor incoming porch visitors from head to toe while eliminating blind spots right beneath the lock where delivery parcels rest.

Because continuous video surveillance demands more power than standard mechanical locking, this model includes an expansive 15,000mAh rechargeable lithium battery rated for up to 4 months of typical performance. To guard against lockouts when the main battery depletes, an integrated secondary tray holds 4 AAA emergency backup batteries that grant an additional month of core locking operation. False detection triggers are mitigated by combining passive infrared (PIR) and radar sensors, which eufy states reduces unneeded alerts by up to 95 percent.

This eufy smart lock with camera functions seamlessly alongside the broader ecosystem and HomeBase 3. While it supports basic smart home commands through Matter, the listing notes that live video streaming operates through the native eufy application. It provides an ideal upgrade path for entryways that lack space for both a video doorbell and a separate keypad deadbolt.

• Integrated 2K HD video camera equipped with HDR and an f/1.8 wide-aperture lens
• Expansive 180-degree diagonal viewing angle with head-to-toe package monitoring
• Dual motion sensing using combined PIR and radar sensors to filter false triggers
• Hybrid power design with a 15,000mAh lithium pack and a 4-AAA battery emergency reserve

For entryways requiring both exterior video monitoring and convenient indoor visibility, this bundle of the eufy Security Smart Lock FamiLock S3 ships directly with the eufy Smart Display E10 smart home hub. While standard smart deadbolts require you to reach for a smartphone whenever motion occurs at the door, the Smart Display E10 acts as a central countertop monitor, allowing household members to see who is standing outside without checking their personal phones.

The lock hardware features an advanced 2K camera with an f/1.6 lens that captures detailed imagery even in dimly lit evening environments. Its 150-degree head-to-toe viewing field captures doorstep parcels clearly. The palm vein recognition lock module reads vascular patterns in 0.6 seconds with 99.9% accuracy, keeping authentication data stored on the hardware to ensure personal biometric information remains private.

Power management uses a high-capacity rechargeable battery pack delivering up to 4 months of standard video and deadbolt duty, backed by 4 AAA emergency batteries providing an additional month of baseline access control. The included Smart Display E10 serves as an operational bridge and video station, making this bundle a complete door communication system for busy households.

• Bundled with the eufy Smart Display E10 tabletop hub for indoor video viewing
• Bright f/1.6 optical aperture for enhanced clarity during night and low-light visits
• 150-degree vertical viewing geometry specifically calibrated for entryway package visibility
• Dual power redundancy with rechargeable lithium power plus secondary AAA cell backup

Standalone camera deadbolt with indoor screen

Best for
High-security setups wanting central storage

The eufy FamiLock S3 Max bundled with the HomeBase S380 hub is the flagship configuration for homeowners building an expansive local-storage home security network. Unlike entry-tier deadbolts that only display camera footage on phones, this model incorporates an integrated Rear Lock Video Screen on the indoor assembly. Anyone standing inside the home can glance directly at the interior lock housing to verify exterior visitors before manually opening the latch, which provides critical convenience for young children and elderly family members.

Biometric processing receives an upgrade on this flagship hardware. The listing indicates ultra-fast 0.1-second palm vein unlocking backed by a 99.99999% biometric recognition accuracy rating. The front exterior escutcheon incorporates a crisp 2560×1440 2K HDR video sensor with an f/1.6 lens and a 150-degree head-to-toe field of view, logging crisp motion clips and visitor chimes directly onto the bundled HomeBase S380 without mandatory subscription fees.

Energy is managed via a 4-month rechargeable main pack supplemented by a 4-AAA battery emergency backup providing an extra month of life. While Matter connectivity links the deadbolt to major platforms, video streams are handled through the native application, making the pairing between the S3 Max and HomeBase 3 the most robust solution for advanced automated recordings.

• Includes HomeBase S380 (HomeBase 3) hub for centralized local storage expansion
• Integrated indoor Rear Lock Video Screen for immediate doorway monitoring
• Advanced 0.1-second palm vein recognition with 99.99999% scanning accuracy
• High-resolution 2560×1440 2K video capture paired with an f/1.6 lens for low-light recording

The eufy FamiLock S3 Max Smart Lock provides the flagship deadbolt hardware as an unbundled, standalone option. It is ideal for homeowners who want the advanced internal screen and 2K camera of the S3 Max line but do not require additional accessories like the Smart Display E10 or the HomeBase S380 hub. If you are upgrading from a conventional eufy door lock with handle arrangement and already have standard deadbolt prep on your door, this unit installs cleanly over your existing deadbolt bore.

On the exterior side, an f/1.6 2K video camera monitors the porch day and night while the palm vein scanner reads unique sub-dermal patterns in 0.6 seconds with 99.9% accuracy. On the interior escutcheon, the built-in Rear Lock Video Screen allows family members to check porch status at a glance without unlocking the door or finding an app. Biometric credentials stay safely encrypted on the lock itself for strict data privacy.

The dual power system pairs a primary rechargeable lithium pack providing up to 4 months of typical use with an emergency backup tray containing 4 AAA batteries for an additional month of operation. It features native Matter compatibility for cross-platform smart home setups alongside direct integration with eufy security gear.

• Standalone deadbolt configuration containing the built-in interior Rear Lock Video Screen
• Sub-dermal palm vein reader providing fast 0.6-second keyless entry verification
• 2K video doorbell camera equipped with an f/1.6 lens for superior low-light recording
• Dual power supply including a primary rechargeable battery and 4 AAA emergency backup cells
