The Aqara G400 Select Wired: A Purpose-Built Wired Doorbell Camera for Smarter Entrance Monitoring
The Aqara Doorbell Camera G400 Select Wired is engineered from the ground up as a dedicated entrance security device. Its wired installation — with PoE support alongside Ethernet and dual-band Wi-Fi — ensures stable, interference-free performance that battery-powered alternatives simply cannot match. With a 1536×2048 video resolution and a wide 165° field of view, it captures a broad sweep of your entrance without needing to reposition the camera as visitors approach.
Key Connectivity and Storage Features
- Ethernet and dual-band Wi-Fi (2.4GHz/5GHz) for flexible wired or wireless connection
- Bluetooth and RF433MHz support for broader accessory compatibility
- Local microSD storage up to 512GB for continuous 24/7 recording
- SMB NAS backup and ONVIF compatibility for NVR integration
On-device AI handles motion detection, person detection, and zone-based intrusion detection locally, while a cloud AI layer adds recognition of faces, animals, packages, and vehicles for richer, more detailed alerts. An intelligent pathway lighting automation feature adjusts a connected spotlight based on zone activity between 18:00 and 23:00 — a practical touch that makes the G400 genuinely useful beyond pure recording. Operating between -20°C and 50°C, it is suited to both home and office environments across most UK climates.
The Aqara Camera Hub G5 Pro (PoE): A High-Resolution Security Camera and Smart Home Hub in One Device
The Aqara Camera Hub G5 Pro (PoE) is not simply a security camera — it is a locally-processed AI camera and a Zigbee, Thread, Matter, and Matter over Thread hub built into a single unit. Powered via PoE over Ethernet, it delivers a stable wired connection with a USB-C port available as an alternative. Its 2688×1520 (2.6K) resolution and 4MP 1/1.8" sensor produce sharp, detailed footage, while the wide f/1.0 aperture gathers up to four times more light than standard lenses, enabling vivid true-colour night vision without switching to black-and-white.
Standout Features at a Glance
- Built-in LED floodlight for enhanced low-light visibility and intruder deterrence
- Fully local 7-in-1 Visual AI and 4-in-1 Audio AI with no cloud dependency
- RTSP streaming to platforms such as Frigate and Blue Iris
- HomeKit Secure Video support for Apple ecosystem users
- SMB NAS support and flexible rotatable stand for wall, ceiling, or surface mounting
The G5 Pro's hub functionality sets it apart from cameras in its class. Rather than acting as a standalone recording device, it can serve as the central node of a broader Aqara or Matter-based smart home — connecting and controlling Zigbee and Thread accessories while simultaneously monitoring your property. For users who want one device to anchor both their security and their wider smart home ecosystem, the G5 Pro is a compelling option.
Doorbell Entry Guard vs. Multi-Protocol Hub Camera: How Connectivity, AI Detection, and Installation Separate These Two Devices
At first glance these two cameras share some common ground — both are PoE-capable, both offer local AI detection, and both support SMB NAS storage. But the differences between them are meaningful and practical, and they start with connectivity.
Protocol Stack Comparison
- G400 Select Wired: Wi-Fi, Ethernet, Bluetooth, RF433MHz
- G5 Pro (PoE): Ethernet, Zigbee, Thread, Matter, Matter over Thread
The G400's broad protocol stack — particularly its Bluetooth and RF433MHz support — makes it compatible with a wide range of accessories and legacy devices that the G5 Pro cannot directly reach. The G5 Pro, by contrast, operates on the standards that define the modern smart home: Zigbee for established sensor ecosystems, Thread for low-latency mesh networking, and Matter for cross-platform device integration. If you are building or expanding a Zigbee or Matter network, the G5 Pro's hub functionality is a genuine advantage the G400 cannot replicate.
AI Detection: Local vs. Cloud-Assisted
Both cameras offer AI-powered detection, but the architecture differs significantly. The G400 combines on-device processing — covering motion, person, and zone-based intrusion — with a cloud AI layer that adds face, animal, package, and vehicle recognition. This layered approach delivers rich detection categories, but advanced features carry a dependency on cloud connectivity. The G5 Pro handles all detection entirely on-device through its 7-in-1 Visual AI (faces, vehicles, people, animals, loitering, lens obstruction, and package recognition) and 4-in-1 Audio AI, with no latency from cloud round-trips and no privacy exposure to external servers. For users who prioritise fully local processing, the G5 Pro's approach is more robust.
Installation Flexibility and Form Factor
The G400 is designed specifically as a doorbell — its form factor and pathway lighting automation are optimised for fixed entrance installation. The G5 Pro's rotatable stand enables flexible positioning on walls, ceilings, or flat surfaces, indoors or outdoors, making it adaptable to a wider range of locations. On storage, both devices support SMB NAS backup. The G400 leads on primary local storage with microSD support up to 512GB, while the G5 Pro pairs SMB NAS and cloud options with RTSP streaming for users integrating into platforms like Frigate or Blue Iris — a workflow the G400 does not support in the same way.
2K Colour Night Vision vs. Wide-Angle 24/7 Coverage: How These Cameras Actually Perform in the Real World
Specifications tell part of the story, but understanding how these cameras behave in everyday conditions is what matters most for security decisions. Across four practical dimensions, the two devices show distinct strengths.
Video Clarity and Field of View
The G400's 1536×2048 resolution and 165° field of view are well-suited to entrance coverage — the wide angle captures approaching visitors, the doorstep, and surrounding areas without needing precise aiming. The G5 Pro's 2688×1520 (2.6K) output from its 4MP 1/1.8" sensor delivers sharper detail in the frame, which is valuable when identifying faces or reading vehicle plates at distance, though its 133° field of view is narrower.
Low-Light Performance
- G5 Pro: f/1.0 aperture gathers up to 4x more light than standard lenses
- G5 Pro: built-in LED floodlight for active illumination in dark environments
- G5 Pro: true-colour night footage without switching to black-and-white mode
- G400: standard night vision suited to typical entrance conditions
Detection Reliability and Operational Resilience
The G5 Pro's fully local 7-in-1 Visual AI and 4-in-1 Audio AI — covering loitering and lens obstruction alongside standard categories — process instantly without cloud latency, making detection reliable even during internet outages. The G400's zone-based intrusion detection and cloud AI layers are effective under normal conditions but depend on connectivity for their most advanced recognition features. On operating temperature, the G5 Pro's range of -30°C to 50°C edges out the G400's -20°C to 50°C, making the G5 Pro the safer choice for exposed installations in colder parts of the UK or in unheated outbuildings during winter months.
What the Aqara G400 Select Wired Does Well — and Where It Has Limitations
The G400 Select Wired brings a well-rounded set of strengths to entrance security. Its wired PoE installation delivers the kind of stable, always-on performance that matters most at a front door, and its combination of Ethernet, dual-band Wi-Fi, Bluetooth, and RF433MHz makes it one of the more connectivity-versatile doorbells in its class. The 165° field of view is purpose-built for doorbell placement, and continuous 24/7 recording with up to 512GB of microSD storage means nothing gets missed. ONVIF compatibility is a practical bonus for anyone already running an NVR system.
G400 Select Wired — Strengths Summary
- Wired PoE installation for stable, interference-free performance
- Wide 165° field of view optimised for entrance coverage
- Up to 512GB microSD local storage with SMB NAS backup
- ONVIF compatibility for NVR system integration
- Intelligent pathway lighting automation for energy-efficient entrance management
The limitations are worth noting honestly. The G400's cloud dependency for advanced AI recognition — faces, vehicles, animals, packages — means its most detailed detection layer is not fully offline-capable. Its operating temperature floor of -20°C, while adequate for most UK locations, falls short of the G5 Pro in extreme cold. And as a doorbell-specific device, it is not designed for flexible repositioning — once installed at the entrance, that is where it stays.
What the Aqara Camera Hub G5 Pro (PoE) Does Well — and Where It Has Limitations
The G5 Pro's headline strengths are its image quality and its hub functionality. The 2.6K resolution from its 4MP 1/1.8" sensor, combined with the f/1.0 aperture and built-in LED floodlight, makes it one of the strongest performing cameras in its category for low-light and night-time environments — earning its place among the best outdoor security light cameras in Aqara's range. All AI processing runs entirely on-device across seven visual and four audio detection categories, with no cloud dependency and no latency from external servers. For users who want homekit secure video cameras outdoor capability, the G5 Pro's HomeKit Secure Video support delivers that natively, and its homekit continuous recording capability fits naturally into Apple Home setups.
G5 Pro (PoE) — Strengths Summary
- 2.6K resolution with true-colour night vision and LED floodlight
- Fully local 7-in-1 Visual AI and 4-in-1 Audio AI — no cloud required
- Built-in Zigbee, Thread, Matter hub expanding its role beyond a camera
- RTSP streaming to Frigate and Blue Iris; SMB NAS storage support
- Broader operating range of -30°C to 50°C for exposed installations
The G5 Pro's limitations are relatively narrow but worth flagging. It does not support RF433MHz or Bluetooth, which means users with legacy RF accessories or Bluetooth-paired devices will need the G400 or a separate hub to bridge those protocols. Its 133° field of view is narrower than the G400's 165°, so placement needs a little more thought to achieve the same breadth of entrance coverage. These are trade-offs, not dealbreakers — but they matter depending on what is already in your home.
Which Aqara Camera Fits Your Smart Home Setup, Technical Needs, and Security Priorities?
Both cameras are strong products, but they are built for different users. Matching each device to the right buyer profile makes the decision much clearer.
Choose the G400 Select Wired If You:

- Want all AI processed locally with no cloud dependency or privacy exposure
- Use Frigate, Blue Iris, or HomeKit Secure Video in your security workflow
The G5 Pro suits technically confident users who want one device to serve multiple roles — camera, hub, and AI processor — without compromise. Its homekit continuous recording capability, RTSP streaming, and fully local AI make it a natural choice for users who are privacy-conscious or who want a camera that fits cleanly into a broader Aqara or Matter-based ecosystem. For those searching for capable homekit secure video cameras outdoor, the G5 Pro is a compelling answer, and its -30°C operating floor makes it a reliable option for exposed outdoor positions through a British winter.
G400 Select Wired or G5 Pro (PoE): The Right Choice Comes Down to Your Setup and Security Goals
The G400 Select Wired is a polished, purpose-built doorbell camera with broad multi-protocol connectivity, a wide 165° entrance-optimised field of view, and flexible local storage — making it an excellent choice for focused entrance security with continuous recording. The G5 Pro (PoE) is a high-performance smart home camera-hub hybrid that excels in low-light clarity, fully local AI processing, and ecosystem integration through Zigbee, Thread, and Matter.
Neither product is universally better. The right choice comes down entirely to whether you need a dedicated smart doorbell with rich connectivity options — including RF433MHz and Bluetooth — or a future-proof camera hub that sits at the centre of a broader Aqara or Matter-based smart home. A few questions worth asking yourself before deciding:
- Which protocols does your existing smart home already use?
- Is entrance-specific installation more important than flexible camera placement?
- How much does fully offline AI processing matter to you?
- What storage and streaming workflow suits your setup — microSD, NAS, RTSP, or HomeKit?
