Data from the official EZVIZ and TP-Link sites.
2026 verdict
2K video, colour night vision and a chime in the box settle this one: the TP-Link Tapo D210 is the better battery doorbell of the pair, and it is the more affordable of the two.
It records to a microSD card of up to 512 GB with free on-device person detection, adds built-in spotlights for colour night vision and infrared to 7.6 m, and its 6400 mAh battery is rated at six months, with the indoor chime included. The EZVIZ CP4 answers with its own niche: a peephole kit with a 4.3-inch indoor touchscreen, a two-year warranty, a voice changer and 1080p video, but it needs an existing viewer hole and its battery life collapses on a busy doorway. Pick the TP-Link Tapo D210 for a wire-free, subscription-free doorbell that fits any door, or the EZVIZ CP4 if your door has a peephole and you want a screen inside.

What the differences mean
Form factor
The EZVIZ CP4 is a peephole kit: the camera replaces the door viewer and a 4.3-inch touchscreen mounts inside, so it only fits a door with an existing hole. The TP-Link Tapo D210 is a conventional wireless camera that mounts on any door with adhesive or screws.
Video and night vision
The TP-Link Tapo D210 records 2K and uses built-in spotlights for colour night vision, plus infrared to 7.6 m. The EZVIZ CP4 is 1080p with black-and-white infrared night vision only, so the Tapo is the sharper and more colourful camera.
Battery
The TP-Link Tapo D210 has a 6400 mAh battery rated at six months, and owners report anywhere from about a month of heavy use to more than five months. The EZVIZ CP4 quotes 90 days of standby, which can fall to about a week when the door faces a busy street.
Detection
The TP-Link Tapo D210 runs free on-device person detection with customizable activity zones. The EZVIZ CP4 has PIR plus human shape detection with only three sensitivity levels and no zoning, so a walkway it cannot mask will keep waking it.
Integrations and warranty
The TP-Link Tapo D210 works with Google Home, Alexa and SmartThings. The EZVIZ CP4 works with Google Home, Alexa and Home Assistant and carries a two-year warranty against the Tapo's shorter one, while adding a voice changer.

The TP-Link Tapo D210 mounts on any door with adhesive or screws and needs no hole or circuit.

- you want a screen indoors, not just a phone

What owners say
Owners of both like that neither asks for a subscription. TP-Link Tapo D210 owners lead with value, noting footage lands on their own microSD card and person detection runs on the device, and they praise the sharp 2K feed, the spotlight-assisted colour night vision and months of battery life, though they warn that the Alexa integration is shallow and that people further down the path can be missed. EZVIZ CP4 owners describe the peephole install as the easiest they have done and love the indoor screen and the microSD recording, but they warn that battery life can fall to about a week on a busy street and that neither the camera nor the screen is waterproof.
Frequently Asked Questions
Which is better overall: EZVIZ CP4 or TP-Link Tapo D210?
The TP-Link Tapo D210 for most doors. It is the more affordable of the two, records 2K with colour night vision to microSD and includes a chime with free person detection. The EZVIZ CP4 is the better pick only when the door already has a peephole and you want a screen inside.
What is the biggest difference between the EZVIZ CP4 and the TP-Link Tapo D210?
The door each one fits. The EZVIZ CP4 is a peephole kit that needs an existing viewer hole and adds a 4.3-inch indoor screen, while the TP-Link Tapo D210 is a conventional wireless doorbell with 2K colour video that goes on any door.
Does the TP-Link Tapo D210 need a subscription?
No. It records to a microSD card of up to 512 GB that you insert in the doorbell and person detection runs on the device itself. A Tapo Care subscription only adds cloud storage and snapshot notifications, and is entirely optional.
Does the TP-Link Tapo D210 need existing doorbell wiring?
No. It is battery powered and mounts with adhesive or screws, so it can go on any door regardless of whether there is existing doorbell wiring. You remove it and recharge it over USB when the battery runs down.
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 TP-Link Tapo D210 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.
