These units not only function as security cameras but also as hubs for other smart devices. To help you decide which is best for your needs, we will delve into a detailed comparison of the Aqara G3 and G4.

Please note that the quality of video, audio, and AI features, as well as the robustness of the associated apps, are also significant factors to consider while comparing these devices.
