Amazon owns Blink, which makes this Prime Day deal particularly hard to explain at face value. The Blink Video Doorbell with Sync Module Core is down to $23, which is 60% off the $59 list price, an all-time low, and a number that leaves almost no room for profit on Amazon’s own hardware. This is a Prime Day deal open to everyone, no membership required.
Two years of battery life and no wiring required
The Blink Video Doorbell runs on three AA Energizer lithium batteries included in the box, with a rated battery life of up to two years of continuous security coverage. That means installation is genuinely wire-free if you want it to be: no electrician, no existing doorbell wiring required, no wall-fishing cables through your door frame. Screw it into the included corner mount, drop in the batteries, connect to the Blink app, and you’re done in minutes. If you do have existing doorbell wiring, connecting to it lets the Blink ring through your home’s existing chime instead.
The head-to-toe HD field of view is the main upgrade over the first generation, delivering a wider vertical angle that captures package deliveries on the ground as well as faces at standing height in the same frame. Infrared night vision covers the same field of view after dark, and two-way audio lets you speak to whoever is at the door through the Blink app from anywhere. Motion alerts notify you on your phone with each doorbell press, and the Sync Module Core included in this bundle handles local communication between the doorbell and the app without requiring a separate hub purchase.
Alexa integration lets you answer the door, check the live feed, and arm or disarm connected Blink devices by voice through any Alexa-enabled speaker or display. The free 30-day trial of a Blink Subscription Plan covers cloud clip storage and person detection alerts during the trial period, with the option to continue after or rely on local storage via a USB drive in the Sync Module.
No competitor sells a complete video doorbell system for $23
Ring’s entry-level video doorbell starts at $59 without a Sync Module equivalent. Nest Doorbell starts higher still. At $23 for a complete system including the doorbell, Sync Module Core, batteries, mounting kit, and corner mount, no competing product in the smart doorbell category comes close to this price for a complete out-of-the-box setup. The gap is not marginal: it’s the difference between an impulse buy and a considered purchase, and Amazon is clearly using Prime Day to push Blink into as many homes as possible regardless of what it costs them on the margin.
The second-generation Blink Video Doorbell improves on the original with the expanded field of view and the updated Sync Module Core, which handles faster local processing and a cleaner setup experience than the previous module required. For a rental apartment, a secondary entrance, or a first smart home security purchase, the combination of wire-free installation and two-year battery life removes every practical barrier to getting started.
At $23 for a complete video doorbell system with two-year battery life and HD night vision, Amazon is selling its own product at a price that makes no financial sense except as a Prime Day statement. The deal is open to everyone, stock at this price is finite, and no rival is going to match it.
