Compare Aqara UWB Smart Lock U400 vs Aqara G350

The Aqara app was seen as useful and feature-rich, but reviewers also flagged setup complexity, a Matter-code issue, and a learning curve for customization.

The Aqara app offers deep PTZ, playback, filtering, preset, privacy, and automation controls. Reviewers like the power and layout, though the huge number of options can feel complex.

The motorized base covers a full 360 degrees and can follow movement around an entire room with little or no blind spot.

Reviewers found the camera’s audio clear enough for practical two-way conversations, with generally good microphone and speaker performance.

Auto-lock was broadly praised and often described as reliable or well implemented, though one reviewer found Aqara app close-detection sometimes delayed.

Battery feedback was mostly positive for USB-C charging, removable/rechargeable design, and long runtime, tempered by concerns about spare or replacement batteries.

Bluetooth-only use was judged weak for this lock because reviewers saw the U400's main value in Thread/UWB rather than basic Bluetooth operation.

The body feels solid and well made, with reviewers generally satisfied by its construction and finish.

Build quality was viewed positively, with reviewers describing a step up from earlier Aqara locks and solid, well-made hardware.

Camera and doorbell integration was described as practical when paired with Aqara or Apple Home video devices, letting users see visitors and unlock from one screen.

The camera remains highly functional without HomeGuardian, which reviewers consider a major advantage. Paid plans add longer history and advanced AI, but some dislike gated features or the forced free trial.

Daytime footage is described as natural and well balanced, preserving subtle colors and textures without an overly processed look.

MicroSD support enables 24/7 recording, giving buyers a dependable fallback when event detection misses something.

The rounded body and removable bunny ears are playful and home-friendly for some reviewers, while others find the look conspicuous or slightly creepy. Removing the sleeve gives it a more conventional appearance.

People, pet, face, gesture, and motion detection are extensive and often effective. Tracking can lag, miss off-angle faces, or become inconsistent in fast movement and difficult lighting.

The 9x digital end of the zoom range remains usable for basic monitoring, but reviewers note visible breakup and reduced detail at maximum magnification.

Door-sense evidence was limited but positive, centered on the built-in gyroscope knowing when the door closes so it can lock without an added sensor.

Door fit flexibility was helped by adapters/cross-bore support, with reviewers calling the physical fit detail useful for nonstandard openings.

The wide and telephoto sensors work together smoothly, providing both room-wide context and sharper close-ups without abrupt visual transitions.

HomeKit can handle convenient 1080p alerts while the camera preserves full-resolution footage locally, giving users both ecosystem convenience and higher-quality archives.

One reviewer valued that the lock could mount without the kind of door drilling required by the previous lock, making the install feel friendlier to existing doors.

Early lighting and shadow alerts were resolved through firmware in one test, indicating updates can meaningfully improve false-trigger behavior.

Feature-update evidence was limited but positive, with one reviewer saying Aqara is good about firmware updates.

The motorized base and wide lens provide near-complete room coverage, with reviewers highlighting 360-degree movement and minimal blind spots.

Fingerprint access was consistently praised as quick, accurate, consistent, or convenient, especially as a backup when UWB is unavailable.

The exterior finish earned a positive note for resisting fingerprints better than expected.

The camera maintained smooth frame rates during demanding local AI processing in one technical test, suggesting the internal hardware can handle simultaneous vision workloads without obvious slowdown.

Guest access was praised through Home app PIN management and temporary/neighbor-style access options.

HomeKit Secure Video works reliably for streaming, recordings, alerts, and automations. Its 1080p ceiling and lack of native PTZ controls leave much of the G350’s hardware unused.

Hub requirements were mixed: reviewers liked avoiding an Aqara hub in Apple Home, but still emphasized the need for a Thread border router for full functionality.

A USB-C cable is included, but the missing power adapter and separately sold mounting hardware feel stingy at this price.

Industrial design was the most mixed area: reviewers liked the sleeker, more mature, minimal look, but others called it bulky, plain, or plastic-looking.

Most reviewers found setup quick and painless through the Aqara app, with flexible freestanding or threaded mounting. Multiple QR codes and separately sold mounting hardware can add confusion or cost.

Installation was usually described as straightforward and fast, with several reviewers finishing quickly, though a few noted tight wiring, small screw holes, or a latch-area snag.

Reviewers liked retaining a physical-key fallback, framing it as a useful mechanical backup rather than a compromised smart-only design.

The keypad was generally usable and responsive, but reviewers also found that it could take extra taps or touches to wake in some cases.

The keyway/cylinder was viewed positively because the reviewer liked that it could be rekeyed rather than forcing a full lock replacement.

One reviewer noticed occasional wide-angle distortion, so the broad view can slightly warp the image in some situations.

MicroSD, NAS, and RTSP options make the G350 unusually flexible and local-friendly. Reviewers value being able to record without internet access or a mandatory subscription.

Lock/unlock speed was one of the strongest themes, especially with UWB; reviewers described fast reactions, instant Home app response, and few delay caveats.

Locking reliability was strongly praised, with reviewers repeatedly reporting flawless, rock-solid, or consistently smooth hands-free unlocking.

Low-light and infrared performance earned strong marks for sharpness and minimal ghosting, though reflective surfaces can affect exposure in difficult placements.

A standard threaded base and image rotation support shelf, wall, and ceiling placement. Its weight and limited tilt angle can make certain mounts less practical.

Infrared night footage is generally described as clear, crisp, and useful. The recurring drawback is that it remains grayscale rather than offering full-color night vision.

Detailed alert controls and duplicate filtering help reduce notification overload, but Aqara alerts may lack rich previews and require tuning for best results.

Notifications earned praise for adding Apple Watch/iPhone confirmation and a quick relock option after UWB unlocks.

The mechanical privacy mode is widely praised because it visibly hides the lenses. Reviewers value the clear physical confirmation that the camera is not watching.

Local AI is fast, privacy-friendly, and capable of recognizing people, pets, faces, gestures, and sounds without constant cloud processing.

RTSP support is a major strength for Home Assistant and local NVR users, including multiple stream resolutions. The lack of ONVIF PTZ control is the main limitation.

The dedicated telephoto lens is a standout, producing sharper close-ups than typical single-lens indoor cameras. Reviewers repeatedly found the hybrid zoom genuinely useful and often impressive.

Reviewers overwhelmingly regard the G350 as an excellent, feature-rich indoor camera and smart-home hub. Its strongest appeal is the combination of sharp video, local control, and broad integrations.

Physical attack resistance drew a caveat: the reviewer appreciated certification but clearly wished the U400 had a stronger Grade 2 rating instead of Grade 3.

The G350 costs more than basic indoor cameras, but many reviewers believe the dual lenses, local storage, AI, and hub functions justify the premium. Value drops for buyers who do not need the smart-home hub.

The app provides configurable privacy masks that can block sensitive areas before footage is stored or shared.

Pan and tilt are usually smooth, fast, and nearly silent, and tap-to-position controls make navigation easy. A few reviewers saw delayed tracking or unreliable position recall after privacy mode.

Remote access was useful when configured, with one reviewer praising fast remote unlock and another noting Aqara-app remote control needs an Aqara hub.

Security features were praised around UWB precision, encryption-related safeguards, and prevention of unintended inside unlocks or relay-style weaknesses.

The G350 is larger and more noticeable than some indoor cameras, especially with the playful sleeve attached.

Smart-home integration was a major strength, with reviewers praising Apple Home, Matter over Thread, responsiveness, major ecosystem support, and future-looking compatibility.

The G350 supports an unusually broad mix of ecosystems and protocols, making it highly flexible today. Matter camera support itself is still immature and limited on most platforms.

As a Zigbee hub, Matter controller, and Thread border router, the camera can connect and bridge many Aqara accessories while reducing the need for a separate hub.

Baby crying, barking, alarms, coughing, and other sounds are recognized locally, with reviewers reporting useful and reliable real-world alerts.

The upgraded speaker is considered louder and more useful than the previous generation, with reviewers reporting clear, workable two-way talk.

Live feeds generally load quickly and connections remain stable, including in Apple Home. Performance still depends on a solid Wi-Fi connection.

Combining camera, Zigbee hub, Matter controller, and Thread border router can simplify larger Aqara installations and reduce extra hardware.

Touchscreen evidence was mixed, with one reviewer naming wake-up attempts as the main complaint.

User access management was positively reviewed for adequate household limits, more granular Aqara controls, and approachable local fingerprint setup.

Value sentiment was favorable but conditional: reviewers called it worth the upgrade or routine-changing, while also noting the price can feel high.

Reviewers consistently praise the crisp 4K wide-angle feed and the extra detail from the telephoto lens. HomeKit’s 1080p cap and low-quality app downloads prevent the hardware from always showing its full potential.

Voice control received limited but positive evidence, with a reviewer saying they wished they had the supported voice-control lock routine at home.

Weather resistance came across well: reviewers said it could face the elements, and one real-world test cited rain, snow, ice, and no missed performance.

The G350 is strictly an indoor camera with no waterproof rating, so it should not be used outdoors or in exposed locations.
