What Is the Blink Doorbell 2?

Overview of the Device

The Blink Doorbell 2 is a compact, battery‑powered video doorbell. It measures roughly 5.2 inches tall and 1.8 inches wide. The unit houses a 1080p camera, infrared night vision, a microphone, and a speaker. Two AA lithium batteries power the device for up to two years under typical use. The doorbell connects to your 2.4 GHz Wi‑Fi network and streams video to the Blink Home Monitor app on iOS or Android.

How It Differs From the First Generation

The original Blink Video Doorbell required a wired connection for continuous power. The Blink Doorbell 2 removes that requirement, offering true wire‑free operation. It also adds improved motion detection, a wider field of view (180 degrees diagonal), and support for Alexa voice announcements. The newer model retains the same affordable price point while delivering better battery efficiency.

Key Features and Specs

Video Quality and Night Vision

The camera records 1080p HD video at 30 frames per second. Infrared LEDs provide clear black‑and‑white footage up to 25 feet in total darkness. Think of it like a security guard that never sleeps and can see in the dark.

Two‑Way Audio

Built‑in microphone and speaker let you hear visitors and speak back in real time. The audio is full‑duplex, meaning both parties can talk simultaneously without echo. This feature is handy for directing delivery drivers or deterring unwanted guests.

Battery Life and Power Management

Two AA lithium batteries deliver up to 24 months of life with average motion activity (about 10 events per day). The app shows a battery percentage and sends low‑power alerts. You can extend life by adjusting motion sensitivity and scheduling active hours.

Motion Detection and Custom Zones

Passive infrared (PIR) sensors detect heat signatures. You can draw up to three custom motion zones in the app to ignore busy streets or swaying trees. This reduces false alerts by up to 70 % according to Blink’s internal testing.

Storage Options

Blink offers a free 30‑day cloud trial. After that, a Blink Subscription Plan stores unlimited clips for $3 per month per device (or $10 per month for unlimited devices). Local storage is not supported on the doorbell itself, but you can save clips manually to your phone.

Installation and Setup

What You Need Before You Start

• Blink Doorbell 2 unit
• Two AA lithium batteries (included)
• Smartphone with the Blink Home Monitor app
• 2.4 GHz Wi‑Fi network name and password
• Phillips screwdriver (for mounting bracket)

Step‑by‑Step Mounting Guide

1. Insert the batteries, observing polarity.
2. Open the app, tap “Add Device,” and select “Doorbell.”
3. Scan the QR code on the back of the unit.
4. Connect to your Wi‑Fi network when prompted.
5. Choose a mounting location within 30 feet of your router for strong signal.
6. Attach the mounting bracket using the supplied screws and anchors.
7. Snap the doorbell onto the bracket; it clicks securely.
8. Test the live view and adjust angle if needed.

Tips for Optimal Wi‑Fi Performance

Place the doorbell on a wall that faces the router, avoiding thick brick or metal. If signal is weak, add a Wi‑Fi extender or mesh node nearby. The Blink Doorbell 2 only uses 2.4 GHz, so ensure that band is enabled on your router.

Performance in Real Life

Daytime Video Clarity

In bright sunlight the 1080p sensor captures sharp details like license plates and facial features. Colors stay natural, and the wide 180‑degree view covers the porch and walkway.

Night Vision Effectiveness

Infrared LEDs illuminate up to 25 feet. Test footage shows clear outlines of people and packages even in pitch‑black conditions. The automatic IR cut filter switches seamlessly at dusk.

Motion Alert Speed

Push notifications arrive within 2–3 seconds of detection. The app lets you view a live snapshot before opening the full video. This rapid response is comparable to higher‑priced wired models.

Battery Real‑World Longevity

Users reporting 12–15 motion events per day typically see 18–20 months per battery set. Cold climates can reduce life by 10–15 %; keeping the unit sheltered helps.

Smart Home Integration

Alexa Voice Announcements

Enable the Blink SmartHome skill in the Alexa app. When the doorbell detects motion or someone presses the button, Alexa can announce “Someone at the front door” on Echo devices. You can also ask “Alexa, show me the front door” to pull up the live view on Echo Show.

Routine Automation

Create routines such as “When motion detected after sunset, turn on porch lights.” This adds a layer of deterrence without extra hardware.

IFTTT and Other Platforms

Blink does not natively support IFTTT, but you can use Alexa routines as a bridge to trigger other smart devices. For advanced users, the Blink API (developer preview) allows custom integrations.

Maintenance and Battery Tips

Cleaning the Lens

Wipe the camera lens with a microfiber cloth every few months. Dust or spider webs can blur night vision. Avoid harsh chemicals; water or lens cleaner is sufficient.

Battery Replacement Best Practices

• Use only AA lithium batteries (e.g., Energizer Ultimate Lithium).
• Replace both cells at the same time to maintain balanced voltage.
• Dispose of old batteries per local recycling guidelines.

Firmware Updates

The app automatically downloads firmware when the doorbell is online. Keep the app updated to receive security patches and new features. You can force a check in Device Settings → Firmware.

Seasonal Adjustments

In winter, lower motion sensitivity to reduce false triggers from snow. In summer, increase sensitivity if you want to capture more activity. Schedule “Do Not Disturb” hours for quiet nights.

Final Thoughts

The Blink Doorbell 2 strikes a sweet spot between price, performance, and ease of use. Its wire‑free design means you can secure a rental property or a historic home without drilling holes. The two‑year battery life eliminates frequent ladder trips. Alexa integration adds voice convenience that many competitors reserve for premium models. While cloud storage requires a subscription after the trial, the cost is modest compared to other brands. If you want a reliable, affordable video doorbell that you can set up in an afternoon, the Blink Doorbell 2 deserves a spot on your shortlist.
