2026 verdict
Pick the Google Nest Doorbell (wired, 2nd Gen) for a wired doorway in a Google home, and take the EZVIZ CP4 only if you have a peephole and no wiring.
The Google Nest Doorbell (wired, 2nd Gen) hardwires to existing doorbell wiring, processes detection on the device for fast and accurate people, package, animal and vehicle alerts, and offers a tall head-to-toe view with HDR, dual-band Wi-Fi, custom motion zones and free event clips from the past three hours, with Google Home, Alexa, SmartThings and Home Assistant on top. The EZVIZ CP4 replaces a door viewer without drilling, adds a 4.3-inch indoor touchscreen that doubles as the chime, records 1080p to a microSD card with no subscription, and includes a voice changer, but it is a 2.4 GHz-only battery device with motion and human-shape detection alone. The EZVIZ CP4 is the cheaper and the better rated of the two. Buy the Google Nest Doorbell (wired, 2nd Gen) for fast smart alerts on a wired door, and the EZVIZ CP4 for an apartment peephole.

What the differences mean
Installation and power
The Google Nest Doorbell (wired, 2nd 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 fits the viewer hole and needs no wiring, but it must be recharged according to how busy the doorway is.
Smart detection
The Google Nest Doorbell (wired, 2nd Gen) distinguishes people, packages, animals and vehicles on the device and supports custom motion zones. The EZVIZ CP4 offers motion and human-shape detection only, with no zone masking, which is why constant passers-by drain it.
Video
The Google Nest Doorbell (wired, 2nd Gen) records HD video with HDR in a tall 3:4 view, which keeps faces readable in bright backlighting. The EZVIZ CP4 records 1080p with a wider 166-degree diagonal view and infrared night vision, but no HDR.
Wireless
The Google Nest Doorbell (wired, 2nd Gen) uses dual-band 2.4 and 5 GHz Wi-Fi. The EZVIZ CP4 is limited to 2.4 GHz, which is enough for a peephole camera but a weaker link on a crowded network.
Ecosystem
The Google Nest Doorbell (wired, 2nd Gen) fits Google Home, Alexa, SmartThings and Home Assistant. The EZVIZ CP4 reaches only Google Home, Alexa and Home Assistant, so it misses SmartThings and Apple Home alike.
Which one to buy if
- you have existing doorbell wiring and want fast smart alerts
The Google Nest Doorbell (wired, 2nd Gen) processes detection on device for near-instant people and package alerts and never needs a charge.
- you rent an apartment and cannot drill or wire
The EZVIZ CP4 fits the existing peephole and needs no holes or cabling, the cleanest rental install.
- you want a screen inside the home
The EZVIZ CP4 includes an indoor touchscreen that rings and can wake on motion; the Google Nest Doorbell (wired, 2nd Gen) relies on a Nest speaker, Hub or a chime adapter.
- you want the widest platform support
The Google Nest Doorbell (wired, 2nd Gen) works with Google Home, Alexa, SmartThings and Home Assistant, while the EZVIZ CP4 does not support SmartThings.
- you want to record without a subscription
The EZVIZ CP4 writes events to a microSD card of up to 512 GB, while the Google Nest Doorbell (wired, 2nd Gen) keeps only the past three hours of event clips free.

What owners say
Google Nest Doorbell (wired, 2nd Gen) owners upgrading from an older Nest Hello repeatedly note how fast notifications arrive, a few seconds instead of twenty or thirty, and credit the on-device processing. They love the package detection, including an alert when a package is picked up, the tall view that shows visitors head to toe and parcels on the ground, and an install on existing wiring that some finish in under five minutes. Their complaints are the tiny, fiddly wiring screws, the missing chime in the box and a chime adapter that is hard to source, and full history needing a subscription. EZVIZ CP4 owners praise the no-drill peephole install, the indoor touchscreen that anyone in the household can use, and the option to record to a memory card and skip a subscription, but warn that battery life collapses on a busy doorway and that the camera is not waterproof.
