Arlo Video Doorbell 2K (2nd Gen)
About this product
The Arlo Video Doorbell 2K (2nd Gen) is a video doorbell that can be installed wire-free on its rechargeable battery or connected to existing doorbell wiring. It is aimed at buyers who want a polished app, a very wide view of the doorstep and tight integration with other Arlo cameras, and who are prepared to pay for a subscription to get the most from it.

Key features
- 2K video: 1944 x 1944 resolution in a square format with HDR, which helps balance bright skies and shaded porches.
- 180-degree diagonal field of view: shows visitors from head to toe, plus parcels left at the door.
- Battery or wired: runs on a built-in rechargeable battery or hardwires to a compatible doorbell transformer.
- Night vision: infrared LEDs for seeing visitors after dark.
- Two-way audio: full-duplex conversation through the app, with visitors able to leave a voice message.
- Integrated siren: can be triggered manually or automatically from the app.
- Smart home support: works with Alexa, Google Assistant and IFTTT, and has a weather-resistant design.
What we like
- A wide, tall picture of the porch from the square 2K sensor.
- Flexible power, suitable for homes with or without doorbell wiring.
- Full-duplex audio, so both sides can talk naturally.
- Visitors can leave a voice message if you cannot answer.
- Fits neatly alongside other Arlo cameras in one app.
What to consider
- Stored video recordings, AI detection of people, packages and vehicles, and activity zones all require an Arlo Secure plan.
- Without a plan you mainly get live view and basic notifications.
- The battery is not removable, so the doorbell must be taken down to charge when used without wiring.
- An Arlo chime is sold separately.
Who should buy it
The Arlo Video Doorbell 2K is a strong pick for people who already own Arlo cameras, or who want a refined app experience and a wide view of the doorstep. It suits both renters using battery power and homeowners with existing wiring who want a 2K video doorbell that stays charged.
It is less attractive if you want to avoid ongoing fees, because recorded video and smart alerts depend on a paid plan. Buyers who want local storage with no subscription should look at doorbells built around that approach.
How it compares
The Arlo Video Doorbell 2K sits towards the premium side of the battery doorbell category. Budget doorbells cost less and sometimes include local storage, but their apps and smart home support are often more basic. HD doorbells, including Arlo’s own HD version of this model, cost less than 2K versions and show less detail. Wired-only doorbells avoid charging altogether. As general guidance, subscription costs differ between brands and add up over the years, so factor the plan into the comparison along with the hardware.
What to check before you buy
- Resolution version: Arlo sells the second-generation doorbell in both HD and 2K versions with similar names. Make sure the listing states 2K.
- Chime: when hardwired, the doorbell can ring a compatible existing chime. Otherwise plan for phone alerts or a separate chime.
- Wi-Fi: it connects on the 2.4 GHz band, so check the signal at your front door.
- Wiring: check your transformer is in the supported 8 to 24 V AC range if hardwiring.
- Colour and bundles: colours and bundles with extra cameras exist.
