Sharper video tips the balance: the Arlo Video Doorbell 2K (2nd gen) beats the Aqara Smart Video Doorbell G4 in this video doorbell matchup on price, owner reception, integrations, alerts and customizable motion zones, with 2K resolution, a 180 degree diagonal view and SmartThings support, though its smart alerts, motion zones and video history run on an Arlo subscription. The Aqara answers with local storage and door extras: microSD recording plus 7 days of free cloud, offline and power-cut event history, familiar face alerts, voice changing, automatic replies and a chime in the box. Both are rated for about 4 months per charge and work with Google Home, Alexa and Home Assistant, while Apple Home is native on the Aqara and needs an Arlo SmartHub on the Arlo. Take the Arlo Video Doorbell 2K (2nd gen) for image quality and detection; take the Aqara Smart Video Doorbell G4 to skip the subscription.
