2026 verdict
The Eufy Video Doorbell S220 is the stronger battery doorbell of this pair, and it wins on price, battery life and customizable motion zones.
It records sharp 2K locally to a eufy HomeBase with no subscription, runs roughly one to two months between charges in heavy traffic and longer in normal use, and its on-device person detection is the feature owners rate highest, backed by proven multi-year durability. The EZVIZ CP4 answers with a different idea: a peephole kit that adds a 4.3-inch indoor touchscreen, a two-year warranty, a voice changer and microSD recording up to 512 GB, though its 1080p image and short battery life on a busy doorway are the trade-offs. Pick the Eufy Video Doorbell S220 if you want subscription-free local recording and already own a eufy HomeBase, or the EZVIZ CP4 if your door has a peephole and you want a screen inside.

What the differences mean
Hub requirement
The Eufy Video Doorbell S220 is the add-on version, so it only works and stores recordings alongside a eufy HomeBase, which is not in this box. The EZVIZ CP4 is standalone: it records to its own microSD card and needs no hub.
Resolution
The Eufy Video Doorbell S220 records 2K, while the EZVIZ CP4 is 1080p. If reading a face or a parcel label on the phone matters, the Eufy has the sharper sensor.
Battery life
The Eufy Video Doorbell S220 is quoted at around six months and owners report one to two months in heavy traffic and up to about a year in normal use. The EZVIZ CP4 quotes 90 days of standby, but that can fall to about a week when the door faces a busy street.
Two-way audio
The Eufy Video Doorbell S220 is the weaker of the two here, with noticeably laggy two-way audio, so it is better as a doorbell and camera than as a conversation device. The EZVIZ CP4 brings the alert in like a phone call you can answer or decline and adds a voice changer.
Form factor
The EZVIZ CP4 is a peephole kit that replaces an existing door viewer and puts a 4.3-inch touchscreen inside, with a two-year warranty. The Eufy Video Doorbell S220 is a conventional camera that mounts beside the door and fits any doorway, backed by one of the longest durability records owners report in this category.
Which one to buy if
- you already own a eufy HomeBase
The Eufy Video Doorbell S220 pairs with the HomeBase for local recording with no subscription and joins your existing Eufy cameras.
- you want the sharper image of the two
The Eufy Video Doorbell S220 records 2K against 1080p on the EZVIZ CP4.
- your door already has a peephole
The EZVIZ CP4 replaces the existing viewer and adds a screen inside with no drilling or wiring.
- you want a screen indoors, not just a phone
The EZVIZ CP4 includes a 4.3-inch indoor touchscreen that doubles as the chime.
- you want a doorbell that needs no hub at all
The EZVIZ CP4 records to its own microSD card, while the Eufy Video Doorbell S220 requires a eufy HomeBase.

What owners say
Eufy Video Doorbell S220 owners keep coming back to the same two things: no monthly fee with local recording to a eufy HomeBase or SD card, and durability, with units still working like new after five-plus years; they rate the 2K image and near-flawless person detection highly, and the recurring complaints are that it is the add-on version that needs a HomeBase, two-way audio that is noticeably laggy and the occasional missed event. EZVIZ CP4 owners love the peephole install, the indoor screen and the subscription-free microSD recording, but they warn about battery life on a busy landing and that neither unit is waterproof.
Frequently Asked Questions
Which is better overall: Eufy Video Doorbell S220 or EZVIZ CP4?
The Eufy Video Doorbell S220, if you own or want a eufy HomeBase. It is 2K, has a long battery life and near-flawless person detection, all with no subscription. The EZVIZ CP4 is the better fit for a door with a peephole where you want a screen inside, and it is the one that stands alone without a hub.
What is the biggest difference between the Eufy Video Doorbell S220 and the EZVIZ CP4?
The Eufy Video Doorbell S220 is an add-on doorbell that needs a eufy HomeBase to work and store video, while the EZVIZ CP4 is a standalone peephole kit with an indoor screen and its own microSD recording. One needs a hub, the other needs a peephole.

Existing eufy HomeBase owners, anyone who wants subscription-free 2K video and long battery life, and buyers who value a doorbell that lasts for years over the latest features.
