Blink Video Doorbell (2nd Gen) Review: Worth It?

The original Blink Video Doorbell launched in 2021 and was, for the price, a solid first effort. However, after four years it was showing its age — 1080p resolution, a narrow 135° field of view, and two AA batteries that struggled to hit the advertised battery life. In 2025, Blink replaced it with a proper second generation, and the upgrades are meaningful. This review covers the 2nd gen model specifically; if you’re still running the original, the differences are worth knowing before you decide whether to upgrade.

What Changed in the 2nd Generation

The 2nd gen Blink Video Doorbell launched in May 2025. Before getting into the full review, here’s what’s new compared to the original:

• Resolution: 1440p HD (up from 1080p), with a 1:1 square aspect ratio for head-to-toe coverage
• Field of view: 150° (up from 135°), wide enough to see packages on the ground at your feet
• Battery: Three AA batteries (up from two) — Blink claims up to two years with a Sync Module
• Person detection: Added, though it requires a subscription
• Sync Module: Now ships with the new Sync Module Core (smaller, USB-C powered)
• Design: Slightly chunkier body to accommodate the third battery, new discrete status LED in the corner (replacing the bright ring on the original)

One tradeoff: the included Sync Module Core does not support local USB storage. To save clips locally, you’ll need a Sync Module 2 (USB-A thumb drive, up to 256GB) or Sync Module XR (microSD, up to 256GB) — both sold separately. More on that in the storage section.

Setup and Installation

Setup is handled through the Blink app on iOS or Android. As is typical with Blink, the box contains minimal paper documentation — download the app and follow the on-screen prompts. The process starts with the Sync Module Core, which connects to your Wi-Fi. From there, the doorbell is added by scanning its QR code.

A couple of practical notes from installation: the mounting plate attaches with two screws, and Blink includes a paper template that makes drilling pilot holes much easier than eyeballing it. A corner mount accessory is included in the box, which is handy for angled installations. The doorbell itself snaps onto the plate — push forward, then press downward until it clicks. Getting it off requires the included release tool, which is worth keeping somewhere accessible for battery changes.

I ran into the same issue I had with the original — the house’s existing doorbell wiring wasn’t sufficient for a hardwired connection. That means no chime through the home’s built-in speakers. Instead, Blink offers two alternatives: pair it with a Blink Mini 2 camera as a plug-in indoor chime, or use an Alexa-enabled device like an Echo Dot for audio alerts. The Alexa integration works well and is, frankly, a better experience than most traditional chimes anyway.

Video Quality

The jump from 1080p to 1440p is noticeable. Additionally, the 1:1 square aspect ratio matters more than the resolution bump in everyday use — you can now see a visitor’s full height from head to foot and spot a package sitting on the ground in the same frame. That’s genuinely useful, and it’s the feature Blink is most prominently marketing for good reason.

The 150° field of view is wide enough to cover a porch or entryway without needing to angle the camera sideways. Colors are accurate and the image is sharp enough to make out faces clearly. Night vision uses 850nm infrared and performs well — adequate detail at typical doorbell distances.

One consistent note across multiple reviews: the video isn’t the sharpest in class, but it is more than sufficient for identifying people and packages. For the price, it’s exactly what you need.

Motion Detection and Alerts

Motion settings in the Blink app include sensitivity adjustment, re-trigger time, and clip length. There’s also a toggle to end the clip early if motion stops — useful for conserving battery and storage space. A setting of 5 for sensitivity works well for capturing motion close to the door without triggering on distant passing cars.

Activity zones let you draw regions within the frame where motion should trigger an alert. Privacy zones, by contrast, block out areas that should never record — useful for a shared driveway or a neighbor’s window in the frame.

Person detection is available with the 2nd gen, but it requires a Blink subscription plan. Without a subscription, you get motion-triggered clips but no AI-filtered alerts. That’s a meaningful tradeoff to understand before buying — basic motion alerting is free, but smarter notifications cost extra.

Three video quality settings are offered: Saver, Standard, and Best. Best delivers the full 1440p experience; Saver conserves battery and storage at reduced resolution.

Battery Life

Blink claims up to two years on three AA lithium batteries when used with a Sync Module — the module offloads some of the processing that would otherwise drain the doorbell’s batteries faster. That two-year figure is a best-case estimate under light use; heavy traffic, frequent live views, and cold weather will reduce it meaningfully.

Battery status in the app shows as “OK” or “Replace” — no percentage, same as the original. That’s a minor frustration but not unusual for Blink devices.

Blink recommends lithium batteries, not rechargeable ones. The included Energizer lithium AAs are a good choice; for replacements, Energizer Ultimate Lithium AA batteries are what Blink uses in the box and what I’d stick with.

Storage: What You Need to Know

This is the most important section for buyers coming from the original model or from other Blink cameras.

The 2nd gen Video Doorbell ships with the Sync Module Core. That module is the system hub — it connects your doorbell to Wi-Fi and enables the two-year battery life claim. However, the Sync Module Core does not support local storage. There is no USB port on it.

Your storage options are therefore:

• Blink subscription (cloud): Starting at $3.99/month per camera or $39.99/year. Stores clips in the cloud with 60 days of history. Person and vehicle detection, live view recording, and video sharing are also unlocked. See our full Blink subscription plan breakdown for details.
• Sync Module 2 (local, USB): Sold separately (~$35). Supports a USB thumb drive up to 256GB for local clip storage at no ongoing cost.
• Sync Module XR (local, microSD): Sold separately (~$70). Supports a microSD card up to 256GB and extends outdoor camera range. Best option if you have multiple Blink outdoor cameras.

Accounts created on or before April 15, 2020 still have grandfathered free cloud storage — 7,200 seconds (2 hours) per Sync Module. That legacy storage works with the Video Doorbell if your account qualifies.

In addition, note that if you already have a Sync Module 2 or XR set up for other Blink cameras, you do not need the included Sync Module Core — you can add the doorbell directly to your existing system.

Smart Home Integration

The Blink Video Doorbell works with Amazon Alexa. Google Home and Apple HomeKit are not supported — this is an Amazon product and it shows. If you’re in a Google or Apple smart home ecosystem, this doorbell won’t fit neatly into your setup.

The Alexa integration, however, is genuinely well done. Your Echo devices can announce when someone presses the doorbell, display the live view on an Echo Show, and allow two-way audio from the screen. For households already running Alexa throughout the home, this makes the Blink doorbell a natural fit.

IFTTT is also supported for those who want to build custom automations.

Hardware and Build

Available in white or black, the 2nd gen is slightly thicker than the original due to the third battery, but it still mounts cleanly on a doorframe or wall. IP65 weatherproofing means it can handle rain, dust, and temperatures from -4°F to 113°F. The oval doorbell button is larger than on the original, which is a small but appreciated improvement.

The old bright status ring around the button is gone — replaced by a small discrete LED in the corner. That’s a design improvement; the original’s ring was quite visible and some users found it obtrusive at night.

Audio quality through two-way talk is acceptable — clear enough for a doorbell interaction, though not high-fidelity.

What the Blink Video Doorbell Is Missing

• No Google Home or HomeKit: Alexa only.
• No built-in chime: Requires a Blink Mini 2 or Alexa device for indoor audio alerts without wiring.
• Person detection requires a subscription: Free motion alerts only without a plan.
• Local storage requires an upgraded Sync Module: The included Core module is cloud/subscription-only.
• No battery percentage display: “OK” or “Replace” only.
• No color night vision: Standard IR only.
