What’s in the box?

Your package includes:

• 1 Blink Wired Doorbell 2K+
• 1 Wall mounting kit
• 1 Drill template
• 1 Doorbell removal tool
• 1 Bypass cable

Which tools do you need for installation?

Before installation, gather these tools:

• Power drill with appropriate drill bit (for your wall type: wood, brick, concrete or render).
• Phillips-head screwdriver (PH2 for wire terminal connections).
• Flat-head screwdriver (for device removal if needed).

Which power source does Wired Doorbell 2K+ require?

Wired Doorbell 2K+ operates exclusively on wired power (10–24V AC for US/CA/MX; 8–24V AC for EU/UK) through existing doorbell wiring. Unlike battery-powered doorbells, it has no battery backup and requires continuous, uninterrupted power to function.

Why won’t my existing in-home mechanical chime work with this doorbell?

Wired Doorbell 2K+ requires a bypass cable to be installed at your in-home mechanical chime, which redirects power directly to the doorbell. This means your existing mechanical chime will no longer function. You’ll receive notifications through the Blink app or compatible Alexa devices, or you can purchase a compatible digital chime, like the Blink Mini camera or Blink Chime (sold separately).

Why do I need to install a bypass cable?

The bypass cable must be installed at your in-home doorbell chime location to ensure consistent power delivery to your Wired Doorbell 2K+, allowing reliable, continuous performance.

What is 2K video resolution?

Wired Doorbell 2K+ captures video at up to 1920x1920 pixels (2K resolution) at 24 frames per second (FPS), providing significantly clearer detail than standard 1080p doorbells. Combined with Local Tone Mapping (LTM) for improved dynamic range, you’ll see better detail in both bright and shadowed areas.

How does Wired Doorbell 2K+ handle different lighting conditions?

Wired Doorbell 2K+ automatically balances bright and dark areas in the same frame, so you can clearly see details in both shadows and highlights at the same time.

Which video resolution options are available?

Wired Doorbell 2K+ offers three quality settings:

• Best: 1920x1920 pixels (~2K resolution) at 24 FPS - Default setting.
• Standard: 1440x1440 pixels (~1080p) at 24 FPS.
• Saver: 960x960 pixels (~720p) at 15 FPS.

Higher resolutions provide better video clarity. You can change this setting at any time in the Blink app under Device Settings, Video and Photo Quality.

What field of view does the camera provide?

Wired Doorbell 2K+ features a 140° horizontal x 140° vertical field of view with 173° diagonal coverage, angled 5 degrees downward to capture your doorstep and visitors clearly.

How far can the camera see at night?

The infrared Night Vision illuminates up to 33 feet (10 metres) from the doorbell, allowing clear visibility of visitors even in complete darkness using 850nm infrared wavelength.

Which types of motion can Blink Wired Doorbell 2K+ detect?

With an active Blink plan (sold separately), Blink Wired Doorbell 2K+ can detect specific types of motion including Person Detection and Vehicle Detection and send you a notification for each type. 

To learn more, visit Using Smart Detection Features.

Can I customise which areas trigger motion alerts? 

Yes. You can set up Activity Zones using a grid to focus on specific areas. You can also set up Privacy Zones to block areas from being recorded entirely.

Does Motion Detection work at night?

Yes. Motion Detection works in any lighting condition: daytime, dusk, nighttime and dawn. Motion detection may be impacted at nighttime when infrared (IR) mode is off.

What is Pre-Roll Video?

Note: This feature is only available on wired devices with a Blink plan.

Pre-Roll Video captures a few seconds of footage before motion is detected, adding it to the beginning of your recorded clip so you can see what triggered the event.

Which audio features does this doorbell offer?

Wired Doorbell 2K+ features:

• Digital Microphone: Captures clearer audio than analogue microphones.
• Noise Suppression: Advanced DSP (Digital Signal Processing) reduces background noise, making conversations clearer even in windy or noisy environments.
• Echo Cancellation: Eliminates feedback during two-way conversations.
• 75 dB Speaker: Clear audio output at 3.2 feet (1 metre) distance.

These improvements ensure you can communicate clearly with visitors even in challenging outdoor conditions.

How do I use two-way audio during Live View?

To use two-way audio during Live View:

1. Select Tap to Unmute.
2. Speak into your mobile device.
3. Select Tap to Mute when finished.

Does two-way audio work with Alexa devices?

Yes. Two-way audio works with Alexa-compatible devices like Echo Show. To learn more, visit Alexa: Live View and Two-Way Audio.

Which Wi-Fi requirements does the doorbell need?

You will need:

Network specifications:

• 2.4 GHz Wi-Fi network (802.11 b/g/n).
• High-speed internet with minimum upload speed for each resolution:
  • 6 Mbps for Best - 1920x1920 pixels (24 FPS).
