This Bundle, Which Includes the Blink 2K+ Doorbell and Five Cameras, Is 71% Off During Prime Day in October.
Ahead of Amazon’s October Prime Day sale, the Blink Battery Doorbell 2K+ video doorbell and five 2K+ outdoor cameras are on sale for $119.99, down from $419.98—a 71% discount and the lowest price ever for this kit. That’s roughly $20 per device, a significant price reduction for a whole-home security system .

The main advantage is the ability to cover the entire area without wiring, as all six units run on AA lithium batteries. Each Outdoor 2K+ camera shoots 2K video with color night vision, is IP65-rated for weather protection, and offers 4x zoom, so you can check if a box on the porch is yours or get a clearer view of a car in the driveway. However, color night vision is dependent on ambient light, and the camera switches to black-and-white infrared vision when it’s insufficient. Blink’s claimed two-year battery life assumes using the 1080p resolution performance settings with typical usage, so running in full 2K resolution mode with constant motion events will shorten that life, according to a PCMag review . These cameras also work with accessories designed for the Outdoor 4, including a floodlight mount and an additional battery pack (sold separately), for those looking to expand the system.
As for the doorbell, it records video in 1920 x 1920 resolution with a 140-degree by 140-degree square field of view, showing the visitor from head to toe. It can be installed wirelessly or connected to an existing doorbell, which is the only way to activate your mechanical chime; otherwise, you’ll need a Blink Chime to hear the chime from inside the room. The kit also includes a Core sync module for connecting all those cameras, but it can’t store clips locally, so saving and sharing footage after the 30-day trial means paying for cloud storage, with plans starting at $4.99 per month or $49.99 for the first year (and $69.99 per year thereafter) for one camera, or $19.99 per month or $149.99 for the first year, then extending to $199.99 per year for unlimited devices. Without a subscription, you can still use live viewing and receive motion alerts.
