2026 verdict
A screen indoors and local recording settle this one: the EZVIZ CP4 wins this pairing on price, owner rating, warranty, integrations, storage and voice changing.
It records events to a microSD card of up to 512 GB with no subscription, includes a 4.3-inch indoor touchscreen as the chime and carries a two-year warranty, with Google Home and Home Assistant alongside Alexa. The Ring Battery Doorbell 4K Pro is the sharper camera, with Retinal 4K HDR video, colour night vision, radar-based 3D motion detection and a removable battery for doors with no wiring, but it saves nothing locally and gates video and person, package and vehicle alerts behind a Ring plan. Pick the EZVIZ CP4 for a peephole door with no subscription, or the Ring Battery Doorbell 4K Pro for the best wire-free image and acceptance of the plan.

What the differences mean
Storage and subscription
The EZVIZ CP4 records events to a microSD card of up to 512 GB with no monthly fee and can play them back on the indoor screen. The Ring Battery Doorbell 4K Pro has no microSD slot and no onboard storage, so saved video and the person, package and vehicle alerts need a Ring plan.
Warranty
The EZVIZ CP4 carries a two-year warranty, against one year on the Ring Battery Doorbell 4K Pro. For a device that sits outside all year, that is one of the clearer points in the EZVIZ column.
Video and night vision
The Ring Battery Doorbell 4K Pro shoots Retinal 4K with HDR and colour night vision, the sharpest image of the pair and the reason to pick it. The EZVIZ CP4 is 1080p with black-and-white infrared night vision only.
Power and placement
The EZVIZ CP4 replaces an existing peephole and runs on a battery, so it suits a rental or apartment door. The Ring Battery Doorbell 4K Pro also runs on a removable battery and can optionally hardwire, but it mounts beside the door rather than inside the viewer hole.
Alerts
Both detect people. The Ring Battery Doorbell 4K Pro uses radar-based 3D motion with customizable zones and adds person, package and vehicle alerts behind the plan. The EZVIZ CP4 has PIR plus human shape detection with three sensitivity levels and no zoning, but it adds a voice changer.
Which one to buy if
- 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 local recording with no monthly fee
The EZVIZ CP4 stores events on a microSD card, while the Ring Battery Doorbell 4K Pro keeps nothing without a plan.
- your door has no wiring and you want the sharpest image
The Ring Battery Doorbell 4K Pro runs on a removable battery and shoots Retinal 4K with HDR, well above the 1080p of the EZVIZ CP4.
- you want colour night vision
The Ring Battery Doorbell 4K Pro adds colour night vision, where the EZVIZ CP4 is infrared black and white only.
- you want the longer warranty
The EZVIZ CP4 carries a two-year warranty against one year on the Ring Battery Doorbell 4K Pro.

What owners say
EZVIZ CP4 owners describe a peephole kit that installs in minutes without drilling, a screen inside anyone can use, and subscription-free microSD recording; their warnings are battery life that can fall to about a week on a busy street and a unit that is not waterproof. Ring Battery Doorbell 4K Pro owners single out the clarity of the 4K image, the 10x zoom that makes parcel labels and faces readable, colour night vision and swapping a battery pack without taking the doorbell off the wall, but the lack of a microSD slot and the need for a plan to keep any clip is their most common complaint.
Frequently Asked Questions
Which is better overall: EZVIZ CP4 or Ring Battery Doorbell 4K Pro?
The EZVIZ CP4, by the overall ranking, because it wins more of the compared rows: price, owner rating, warranty, integrations, storage and voice changing. The Ring Battery Doorbell 4K Pro is the better camera and the sharpest wire-free Ring doorbell, but its saved video and smart alerts need a Ring plan.
What is the biggest difference between the EZVIZ CP4 and the Ring Battery Doorbell 4K Pro?
The product and the storage model. The EZVIZ CP4 is a battery peephole kit with an indoor screen and free microSD recording, while the Ring Battery Doorbell 4K Pro is a conventional wireless camera with 4K HDR colour video and radar motion but no local storage and a subscription for saved video.
Does the Ring Battery Doorbell 4K Pro record without a subscription?
No. It has no microSD slot and no internal storage, so saved video requires a Ring plan, as do the person, package, vehicle and Familiar Faces alerts. Live view, two-way talk and a motion notification work without one.
Do I need doorbell wiring to install the Ring Battery Doorbell 4K Pro?
No. It runs on the included Quick Release Ultra battery pack and mounts with a bracket and screws, which is why it suits condos and rentals. You can optionally hardwire it to an 8-24V transformer, and then it will also ring an existing in-home chime.
Does the EZVIZ CP4 need an existing peephole?
Yes. It replaces a standard door viewer, so it only fits a door that already has one, on a leaf between 35 and 105 mm thick. The Ring Battery Doorbell 4K Pro can mount on any door.
Who should buy the EZVIZ CP4?
Apartment dwellers whose door already has a peephole, renters who cannot drill or wire, and anyone who wants a screen indoors plus subscription-free microSD recording.
