2026 verdict
Do you want a peephole camera that needs no wiring, or a wired doorbell with the sharpest video: which is better, the EZVIZ CP4 or the Google Nest Doorbell (wired, 3rd Gen)?
For a wired doorway in a Google home, the Google Nest Doorbell (wired, 3rd Gen) is the better doorbell. It hardwires to existing wiring, records 2K HDR video in a tall 1:1 view, and its on-device alerts separate people, packages, animals and vehicles, with Google Home, Alexa, SmartThings and Home Assistant support and free event clips from the past six hours. The EZVIZ CP4 is a battery peephole camera that fits an existing viewer, with a 4.3-inch indoor touchscreen, 1080p and subscription-free microSD recording, but it is limited to 2.4 GHz Wi-Fi and supports only Google Home, Alexa and Home Assistant. The EZVIZ CP4 is the cheaper and better rated of the two. Buy the Google Nest Doorbell (wired, 3rd Gen) for the sharpest alerts on a wired door, and the EZVIZ CP4 for an apartment peephole.

What the differences mean
Video quality
The Google Nest Doorbell (wired, 3rd Gen) records 2K HDR with a tall 1:1 view, sharp enough to read a package label. The EZVIZ CP4 records 1080p with infrared night vision and a wide 166-degree diagonal view, but no HDR and less detail.
Installation and power
The Google Nest Doorbell (wired, 3rd Gen) hardwires to existing doorbell wiring and never needs charging, with no chime in the box. The EZVIZ CP4 is a battery peephole camera that needs no wiring but has to be recharged according to doorway traffic.
Smart detection
The Google Nest Doorbell (wired, 3rd Gen) distinguishes people, packages, animals and vehicles on device and supports custom motion zones. The EZVIZ CP4 covers motion and human-shape detection only, with no zones, which is exactly why it drains on a busy doorway.
Storage
The Google Nest Doorbell (wired, 3rd Gen) keeps free event clips from the past six hours plus a one-hour offline buffer, with continuous history behind Nest Aware. The EZVIZ CP4 records to a microSD card of up to 512 GB with no subscription, an advantage for local-only recording.
Ecosystem
The Google Nest Doorbell (wired, 3rd Gen) fits Google Home, Alexa, SmartThings and Home Assistant. The EZVIZ CP4 reaches only Google Home, Alexa and Home Assistant, missing SmartThings and Apple Home.
Which one to buy if
- you already have doorbell wiring and want the sharpest video
The Google Nest Doorbell (wired, 3rd Gen) records 2K HDR in a tall head-to-toe view and never needs a charge.
- you rent and can only use the existing peephole
The EZVIZ CP4 fits the viewer hole with no drilling or wiring, the cleanest option for a rental.
- you want to store recordings locally with no subscription
The EZVIZ CP4 records to a microSD card of up to 512 GB, while the Google Nest Doorbell (wired, 3rd Gen) keeps only the past six hours free.
- you want the widest platform support
The Google Nest Doorbell (wired, 3rd Gen) works with Google Home, Alexa, SmartThings and Home Assistant, while the EZVIZ CP4 misses SmartThings.
- you want smart alerts that filter out noise
The Google Nest Doorbell (wired, 3rd Gen) separates people, packages, animals and vehicles on device, cutting the junk notifications the EZVIZ CP4's simpler detection cannot.

What owners say
Google Nest Doorbell (wired, 3rd Gen) owners heap praise on the 2K image, calling it sharp enough to read package labels and faces day or night, and on smart alerts that separate people, packages and vehicles instead of pinging at everything. They describe Live View loading almost instantly with clear two-way audio, an install on existing wiring of about twenty minutes, and the appeal of running the doorbell, thermostat and cameras in one app with the ring showing on a Nest Hub. The recurring complaint is storage cost: without a subscription you get event clips from only the past six hours, and familiar faces and full history are paid. EZVIZ CP4 owners prize the no-drill peephole install, the indoor touchscreen anyone can use, and the option to record to a memory card with no subscription, warning only that battery life collapses on a doorway facing a street.
Frequently Asked Questions
Which is better overall: EZVIZ CP4 or Google Nest Doorbell (wired, 3rd Gen)?

Does the Google Nest Doorbell (wired, 3rd Gen) need a subscription?
Not for basic use. The Google Nest Doorbell (wired, 3rd Gen) gives free event clips from the past six hours and a one-hour offline buffer, but continuous history, longer storage and familiar-face alerts need Nest Aware.
