# Aqara Doorbell Camera G400: An In-Depth Look
Upon the unveiling of the Doorbell Camera G400 featuring Power over Ethernet (PoE) functionality, Aqara captured considerable interest. Although PoE may not entice all users, those who prioritize it frequently disregard alternatives that do not offer this capability. Dual-band Wi-Fi 6 acts as an auxiliary option, yet nothing eclipses the dependability of a wired connection. The Aqara Doorbell Camera G400 ensures this dependability, coupled with on-site AI detection and an elongated aspect ratio intended for package visibility. This article delves into the features and advantages of the Aqara Doorbell Camera G400 tailored for Apple Home users.
## HomeKit Secure Video and Technical Considerations
A noteworthy attribute of the G400 is its compatibility with HomeKit Secure Video (HKSV). This feature enables encrypted recording, facial recognition linked to your Apple Photos library, and adjustable activity zones within the Home app. However, users should be cognizant of specific hardware constraints. Despite the G400 being equipped with a 2K camera, Apple limits HKSV functionality to 1080p resolution. If both the Aqara app and Apple Home are utilized simultaneously, this lower resolution is applied across both services.
To fully exploit the G400’s capabilities in Apple Home, an iCloud+ subscription and a HomeKit hub (like a HomePod mini or Apple TV) are required. While the resolution restriction can be annoying, the smooth integration into the Apple ecosystem offers a considerable benefit. Users receive comprehensive notifications on their iPhone and Apple Watch and can access live streams on their Apple TV whenever the doorbell is pressed.
For those who consider the HKSV restrictions cumbersome, Aqara has integrated support for RTSP and ONVIF, permitting users to stream high-definition video to a Synology NAS while still enjoying the ease of the Home app for regular tasks.
## Comprehensive Video and Local AI
In addition to its Apple Home integration, the G400’s camera hardware is tailored for monitoring front entrances. The Aqara Doorbell Camera G400 boasts a 165-degree ultra-wide viewing angle with a 3:4 aspect ratio, which proves more effective for observing packages left right at the door compared to the conventional 16:9 widescreen format. Furthermore, the camera incorporates 940nm infrared LEDs to deliver efficient night vision.
The G400 conducts person identification and zone intrusion detection locally, negating the requirement for a cloud connection. Users have the option for continuous 24/7 recording straight to a microSD card (up to 512GB) and can automatically back up local footage to a Synology or any SMB-compatible NAS.
## Key Specifications of the Aqara Doorbell Camera G400
Here’s a summary of the principal hardware specifications:
– **Resolution and Field of View:** 2K HD resolution with a 165-degree ultra-wide viewing angle; 3:4 aspect ratio provides a vertical, head-to-toe perspective perfect for detecting packages.
– **Power and Connectivity:** Compatible with PoE, existing 8-24V AC/DC doorbell wiring, and dual-band Wi-Fi 6.
– **Night Vision:** Employs 940nm infrared LEDs for clear video capture in low-light settings.
– **Weather Resistance:** IP65 rated to ensure resilience against wind, rain, and dust.
– **Storage Solutions:** Enabled for local microSD cards up to 512GB for continuous recording, with automatic backups to a NAS.
## Final Thoughts on the Aqara Doorbell Camera G400
Locating a HomeKit Secure Video doorbell that fulfills all criteria can be difficult, but the Aqara Doorbell Camera G400 comes impressively close at a competitive price point. By integrating Power over Ethernet, Aqara tackles one of the key hurdles of smart doorbells: sustaining a robust Wi-Fi signal outdoors. This is especially advantageous for residences with thick walls, like brick structures.
While there is optimism for Apple to improve the features of HomeKit Secure Video in the future, users must currently navigate certain trade-offs. As manufacturers keep innovating, the appeal of local NAS solutions may expand, particularly as compatibility with existing features becomes a priority.
