It wins on price, a two-year warranty, IP65 weather resistance, solar charging that keeps a six-month battery topped up and a built-in light, all away from an outlet. The Eufy Indoor Cam E220 is the better indoor camera by a clear margin: it records 2K instead of 1080p, adds RTSP and Apple HomeKit, holds the better owner rating and detects people, pets and baby crying, where the TP-Link Tapo SolarCam C402 only knows people and vehicles. Both record locally to a microSD card without a subscription. Buy the TP-Link Tapo SolarCam C402 for a wall or a gate with no power, and the Eufy Indoor Cam E220 to watch a room, a pet or a nursery.

What the differences mean

Power and placement

The TP-Link Tapo SolarCam C402 runs on a rechargeable battery kept topped up by its own solar panel, so it goes anywhere with a view of the sun. The Eufy Indoor Cam E220 is wired and needs an outlet, which keeps it indoors near a socket.

Video resolution

The Eufy Indoor Cam E220 records 2K and the TP-Link Tapo SolarCam C402 records 1080p, so the indoor camera gives you more detail to zoom into. The Tapo counters with color night vision and a spotlight, which the Eufy does not offer.

Weather rating

The TP-Link Tapo SolarCam C402 is IP65 rated for rain and dust; the Eufy Indoor Cam E220 has no weather rating and has to stay inside. That single line decides where each one can go.

Alerts

The Eufy Indoor Cam E220 detects people, animals and baby crying. The TP-Link Tapo SolarCam C402 detects people and vehicles but not animals or sound events, so a pet or a baby monitor favors the Eufy and a driveway favors the Tapo.

RTSP and HomeKit

The Eufy Indoor Cam E220 supports RTSP and Apple HomeKit; the TP-Link Tapo SolarCam C402 supports neither and stays in the Tapo app. If you feed a NAS or run the Apple Home app, only the Eufy fits.

Which one to buy if

What owners say

Owners of the two are shopping for different jobs, and their praise splits the same way. Eufy Indoor Cam E220 owners love the clear 2K picture, the pan and tilt that covers a whole room from one spot, and subscription-free local storage that keeps footage private; their recurring complaints are person and pet detection that misses people at a distance and an app that can lag. TP-Link Tapo SolarCam C402 owners praise the solar panel that holds the battery near full through rain and sun, the easy install with proper stainless hardware, and person and vehicle detection with zones that ignore animals; what they warn about is reliability, including units that fail early or fog up, an older hardware revision that drains the battery and will not reconnect, and slow support that charges for return shipping.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
