2026 verdict
Buy the Aqara Smart Video Doorbell G4 if Apple Home is your ecosystem, and choose the EZVIZ CP4 only for a door that already has a peephole.
The Aqara Smart Video Doorbell G4 is one of the few battery-capable video doorbells with HomeKit Secure Video, records to a microSD card or seven days of free cloud with no subscription, and works with Apple Home, Google Home, Alexa and Home Assistant, with local face recognition, automatic replies, custom ringtones and an outdoor voice changer. The EZVIZ CP4 is a peephole camera rather than a wall-mounted doorbell: it fits the viewer hole in an apartment door, adds a 4.3-inch indoor touchscreen and records 1080p to a microSD card, but it supports only Google Home, Alexa and Home Assistant and has no Apple Home. The EZVIZ CP4 is the better rated and more polished of the two. Buy the Aqara Smart Video Doorbell G4 for HomeKit Secure Video and a flexible battery install, and the EZVIZ CP4 for a rental door with an existing viewer.

What the differences mean
Apple Home support
The Aqara Smart Video Doorbell G4 is one of the few battery doorbells with HomeKit Secure Video, which keeps recordings in Apple's ecosystem. The EZVIZ CP4 has no Apple Home support at all, leaving Google Home, Alexa and Home Assistant as its only platforms.
How it installs
The Aqara Smart Video Doorbell G4 mounts beside the door like a normal doorbell and can run wired or on six AA batteries. The EZVIZ CP4 is specific to a peephole: it replaces the door viewer and needs no holes or cabling, but it only fits doors that already have one.
Wireless
Both rely on 2.4 GHz Wi-Fi, so both can struggle through metal doors and concrete. The Aqara Smart Video Doorbell G4 adds a repeater in its chime to help, while the EZVIZ CP4 pairs its indoor screen with the camera directly.
Battery
The Aqara Smart Video Doorbell G4 is rated around four months but owners report draining six AA cells quickly when used heavily on battery. The EZVIZ CP4 is rated up to 90 days of standby, which stretches to months on a quiet landing and falls to about a week on a busy doorway.
Detection and extras
The Aqara Smart Video Doorbell G4 adds local face recognition, automatic replies and a voice changer. The EZVIZ CP4 covers motion and human-shape detection, with a voice changer but no face recognition or automatic replies.
Which one to buy if
- your smart home runs on Apple Home
The Aqara Smart Video Doorbell G4 supports HomeKit Secure Video and installs from the Apple Home app, which the EZVIZ CP4 cannot do.
- you rent an apartment and cannot drill the door
The EZVIZ CP4 drops into the existing peephole with no holes and no wiring, the cleanest option for a rental.
- you want a screen inside the home as well as a phone app
The EZVIZ CP4 includes an indoor touchscreen that rings and wakes on motion, where the Aqara Smart Video Doorbell G4 depends on its chime and your phone.
- you want face recognition and automatic replies
The Aqara Smart Video Doorbell G4 recognizes familiar faces and can answer with pre-set messages, features the EZVIZ CP4 does not have.
- you want a doorbell rated to last through hard weather
The Aqara Smart Video Doorbell G4 is built for a porch and owners report it surviving extreme heat, while the EZVIZ CP4 is not waterproof and belongs on a sheltered door.

What owners say
Aqara Smart Video Doorbell G4 owners coming from Logitech, Wemo, Arlo and Eufy praise how easily it installs, often straight from the Apple Home app and either wired or on battery, and they value the HomeKit Secure Video support, the sharp 1080p picture and the subscription-free microSD storage with seven days of cloud. They also like that it holds up in extreme heat. The complaints are consistent and serious: heavy battery drain on its six AA cells, weaker detection on battery, 2.4 GHz-only Wi-Fi that struggles through metal doors and masonry, microSD recording that needs an internet connection, and software that can be buggy. EZVIZ CP4 owners, in contrast, are mostly happy with a peephole installation that needs no drilling or wiring, an indoor touchscreen anyone can use, and clear day and night video, and they warn only that battery life collapses on a busy doorway and that it is not waterproof.
Frequently Asked Questions

Does the EZVIZ CP4 work with Apple HomeKit?

Do both record without a subscription?
Yes. The Aqara Smart Video Doorbell G4 records to a microSD card with seven days of free cloud, and the EZVIZ CP4 records to a microSD card of up to 512 GB, so neither needs a paid plan.
Why is the Aqara Smart Video Doorbell G4 battery criticized?

Which one fits a standard front door?
