Arlo Video Doorbell 2K (2nd Gen), Wireless or Wired vs TP-Link Tapo D225 2K Video Doorbell with Indoor Chime

These are side-by-side facts taken from each product guide: published specifications, strengths and caveats as their sources state them. This page is not a test, a ranking or a verdict about which model is better.

Arlo Video Doorbell 2K (2nd Gen), Wireless or Wired

A 2.4GHz home where live view and basic alerts are enough without a plan

Arlo's second-generation 2K doorbell runs on a sealed rechargeable battery or on existing doorbell wiring, which also trickle-charges it and connects it to your traditional chime. Live streaming, motion alerts and two-way audio work without a subscription; 60-day history, AI detections and emergency response need a paid plan after the included trial. The manual quotes two different transformer voltages, so check yours first.

Published specifications

  • Quick start guide: models AVD3001 and AVD4001; integrated non-removable battery
  • Manual, hardwiring chapter: 8-24Vac, minimum 0.65A, 50/60Hz supply
  • Manual, troubleshooting chapter: transformer voltage between 16-24V AC
  • Manual: 2.4GHz only; within 300 ft of the router; ports 443 and 80 open
  • Manual: chime disabled by the app at 149-185F; doorbell stops above 185F
  • Listing: IP65, 25 ft black-and-white night vision, built-in siren, USA use only

Strengths

  • Live streaming, motion alerts and two-way audio work with no subscription
  • Hardwiring both trickle-charges the battery and rings your existing chime
  • Angled bracket, wire extensions, screws and release pin are all in the box

Caveats

  • The same manual gives 8-24Vac in one chapter and 16-24V AC in another
  • Switching from wire-free to wired means removing and re-adding the device
  • 60-day history, AI detections and emergency response all need a paid plan

TP-Link Tapo D225 2K Video Doorbell with Indoor Chime

A wired door where you want local recording and no monthly plan

The Tapo D225 ships with its own plug-in indoor chime, both mounting wedges and the fixings, and records to a microSD card of up to 512 GB with no subscription. It runs on a 10,000mAh rechargeable battery or on 8-24V AC wiring. Hardwiring unlocks 24/7 recording and pre-roll, but the quick start guide is clear that doing so means fitting a jumper wire to bypass your existing chime.

Published specifications

  • Datasheet: 2K 4MP (2304x1728), 15/20 fps, 16x digital zoom, H.264
  • Datasheet: 170.6 deg horizontal / 140.1 deg vertical lens; 180 deg diagonal claimed
  • Guide: hardwiring needs an 8-24V AC, 10VA minimum transformer; DC 9-24V also allowed
  • Guide: Always-On 24/7 recording requires the jumper wire that bypasses your chime
  • Datasheet: microSD up to 512 GB, not included; free person, pet, vehicle, package AI
  • Datasheet: doorbell -20 to 45 C, IP66; chime indoor only, 0 to 40 C

Strengths

  • Indoor chime, both wedges, template, adhesive, anchors and wire nuts all included
  • Records to a microSD card with AI detection and activity zones at no monthly cost
  • Runs on battery or wiring, and hardwiring adds pre-roll and 24/7 recording

Caveats

  • 24/7 recording means jumpering out your existing chime, so the old bell stops ringing
  • The USB charger is not supplied and a first charge takes about six hours
  • Datasheet and Amazon fields disagree on resolution, night-vision range and IP rating
