Eufy 4G LTE Cam S330 vs TP-Link Tapo SolarCam C402

For an ordinary backyard with Wi-Fi, the TP-Link Tapo SolarCam C402, which is cheaper, better warrantied and rated for harsher weather. The Eufy 4G LTE Cam S330 wins where there is no Wi-Fi, since its own 4G LTE SIM and 4K pan and tilt are built for off-grid sites.

Connectivity. The Eufy 4G LTE Cam S330 has its own 4G LTE radio and works with no network, while the TP-Link Tapo SolarCam C402 is Wi-Fi only. The Eufy also shoots 4K and pans, against a fixed 1080p view on the Tapo.

No. Both record to a microSD card with no mandatory cloud plan, and the Eufy 4G LTE Cam S330 uses your own SIM data instead of a manufacturer plan. The Tapo also offers optional cloud storage, and the Eufy app prompts a cloud backup the camera does not support.

Only the Eufy 4G LTE Cam S330. It runs on 4G LTE using your own SIM and falls back to Wi-Fi when available, so it suits rural land, gates and outbuildings. The TP-Link Tapo SolarCam C402 needs a 2.4 GHz Wi-Fi network at the mount.

Someone watching a place with no internet who wants 4K detail, pan and tilt, local storage and the option to use cheap third-party SIM data, and has confirmed their carrier and country are supported.

A buyer with Wi-Fi at the mount who wants an inexpensive solar camera that records locally without fees, and values the two-year warranty and IP65 rating, while accepting that reliability varies between units.
