■ The catch — co-equal billing, always
It's overkill for one door. You're paying ~$266 mainly for the HomeBase and its 16 TB headroom — pointless unless you're building a multi-camera eufy system. For a single doorbell the plain E340 gives the same camera for less than half.

The card you still have to buy
"No subscription" rarely means "free storage" — a microSD card is NOT included on most models (Tapo, Wyze, base Reolink). Budget $20-45 for a Class-10/U1/U3 256-512 GB card. Only the eufy E340 (8 GB built-in) and Lorex (32 GB included) record out of the box.
No subscription still isn't no cloud
Push-notification thumbnail previews on eufy, Tapo and Wyze still route a small image through the vendor cloud. If you want zero cloud touch at all, only a fully local NVR/NAS setup like the wired Reolink truly avoids it.
Battery and wiring reality
Battery doorbells need a recharge every 2-8 months; wired models won't work without an existing 16-24VAC transformer. And most battery models are 2.4 GHz Wi-Fi only — a weak front-door signal degrades video and delays alerts.
