Ring Battery Doorbell 2K
$10 under your budget
The cheapest doorbell here that works out of the box on battery alone — no transformer, no electrician, no landlord conversation, and a 173° square sensor that shows a caller head-to-toe.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
The battery is built in, and the plan is not optional. Recharging means taking the whole unit off the wall rather than swapping a pack, and without Ring Home you get live view, two-way talk and notifications with no video saved at all — so $219.96 over three years, more than triple the sticker.

Traps — this verdict avoids
Why the Ring Battery Doorbell 2K is right for you
It avoids every trap below — and for just me, under $80, it is the pick because it delivers:
The plan is the price
Sticker price ranks this field in almost the opposite order to lifetime cost. A $49.99 Ring Wired 2K is $199.96 over three years on the cheapest Ring Home plan; a $99.81 Tapo D225 is $99.81, because nothing is gated behind a subscription. The $29.99 Blink is really about $80 once a Sync Module 2 is added. Compare three-year totals, never price tags.
No plan, no recording
Ring and Arlo save nothing at all without a plan — you get live view, two-way talk and motion notifications, and every event is gone the moment it ends. Nest is the only big-ecosystem exception, keeping 3 hours of free event history. eufy, Reolink, Aqara, TP-Link, Wyze and Blink (with a Sync Module 2) record locally for $0/month.
Wired-only is a wiring bill
The Ring Wired 2K, Ring Wired 4K Pro, Nest 3rd Gen and Reolink need an existing 16-24 VAC transformer — no wiring means ~$15-30 for the part and ~$200 for an electrician. The Ring Wired 2K will not even drive a mechanical chime: budget a Ring Chime or an Alexa speaker on top of a $49.99 doorbell.
