Reolink Video Doorbell B (2nd gen) review

The second-generation battery doorbell: the same square head-to-toe frame with HDR added, and detection that Reolink states runs locally on the device rather than in a cloud service.

The conclusion The best doorbell in this hub. HDR fixes the commonest complaint, and local detection means nothing has to leave the house.

Two changes separate this from the first-generation doorbell below it, and both address things that actually go wrong rather than adding figures.

HDR, which fixes the usual complaint

Point a camera at a doorstep and it is often pointed at the sky behind it. A sensor without HDR exposes for the bright background and renders the caller as a silhouette — the single most common complaint about inexpensive doorbells, and one no amount of resolution fixes. HDR exposes for both, and the face comes back.

If your door faces east, west or open sky, this is the specification that decides whether the footage is usable.

Detection that stays in the house

Reolink states person, vehicle, pet and parcel detection processed locally on the device. Three consequences: it is faster, it still works when the broadband is down, and no clip has to be uploaded to a server to decide whether it contains a person.

For anybody uncomfortable with doorstep footage being processed elsewhere — a reasonable thing to be uncomfortable about — that is the most important line on the specification sheet.

Still a battery doorbell

Which means it sleeps, and the seconds before somebody rings are not recorded. Wired to 8–24 V doorbell wiring it charges its battery but stays in battery mode; the Tapo D235, wired the same way, states that it records those seconds. That remains the one thing this format cannot do.

Who it suits

A bright doorway, and an owner who would rather the analysis happened on their own wall.

Availability

Not found on the American Amazon store, where the buy link falls back to a local search rather than to a page that does not exist.

What reassures, and what does not

Strengths

  • Detection runs locally on the device, stated by Reolink — nothing needs to leave the house to classify a person
  • HDR, which is what makes a backlit caller visible against a bright sky
  • 1:1 view at 150° × 150° × 180°, head to toe
  • Up to 10 months per charge stated (5 minutes of recording a day), or charging from 8–24 V doorbell wiring

Compromises

  • No American listing, so this doorbell carries no price to set against the shelf
  • Battery doorbell, so the approach is still missed
  • Card not supplied
  • Free image notifications capped at 25 a day

The questions we are asked

What does local detection mean in practice?

That the decision "this is a person" is made on the doorbell rather than by uploading the clip to a server. It is faster, it works when the internet is down, and nothing has to leave the house to be classified. For anybody uneasy about doorstep footage being processed elsewhere, it is the single most relevant specification here.

Why does HDR matter on a doorbell?

Because of where doorbells point. A caller standing against a bright sky or a white wall is a silhouette on a camera without HDR — the sensor exposes for the background and the face goes black. HDR is what turns that shape back into a person, and it is the commonest complaint about cheaper doorbells.

Is it worth the premium over the first generation?

HDR and local detection are the two differences that matter, and both address real failures rather than adding numbers. If your door faces a bright aspect, HDR alone justifies it.

Our score

8.4/ 10

The best doorbell in this hub. HDR fixes the commonest complaint, and local detection means nothing has to leave the house.
