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.
