Ring Battery Doorbell (2nd Gen) vs Ring Battery Doorbell 4K Pro

The Ring Battery Doorbell 4K Pro is the better overall pick, ahead on connectivity, alert variety and owner rating. The Ring Battery Doorbell (2nd Gen) costs meaningfully less and still records sharp Retinal 2K video, so it remains the better value for buyers who do not need 4K detail.

Battery design and video resolution. The Ring Battery Doorbell 4K Pro uses a removable Quick Release Ultra battery pack and records in 4K, while the Ring Battery Doorbell (2nd Gen) has a built-in, non-removable battery you have to unmount the doorbell to charge, and it records in 2K.

Only the Ring Battery Doorbell 4K Pro has a swappable battery. Its Quick Release Ultra pack pulls out and recharges over USB-C without taking the doorbell off the wall. The Ring Battery Doorbell (2nd Gen) has a built-in battery, so charging means unmounting the whole unit and plugging it in directly, or hardwiring it for a continuous trickle charge.

The Ring Battery Doorbell 4K Pro has the sharper sensor: 4K with up to 10x enhanced zoom and HDR, against the Ring Battery Doorbell (2nd Gen)'s Retinal 2K with up to 6x enhanced zoom. Both share the same 140 by 140 degree head-to-toe field of view.

Buyers on a tighter budget, or anyone who wants Ring's sharp Retinal 2K video without paying for the 4K sensor or the swappable battery pack.

Buyers who want the sharpest possible image, a battery pack that swaps out in seconds, dual-band Wi-Fi, and Ring's fullest alert set including vehicle detection.
