Expand your Blink security setup for less with this standout deal

Home security cameras rarely see a 46% discount, let alone one built to survive two years without a single battery change.

Amazon’s fourth-generation wireless security camera, now down from its $69.99 list price to $37.99, a $32 saving that makes it one of the cheaper ways to expand a home security setup.

Getting a genuinely capable camera like the Outdoor 4 down to $37.99 is rare, since it still captures 1080p HD footage, runs entirely on battery power for two years, and holds up in weather from well below freezing to well over 100 degrees Fahrenheit.

Two included AA Energizer lithium batteries paired with a Blink Sync Module are what stretch that runtime out to two years, and the whole camera is designed to go up in minutes rather than requiring any complicated wiring or drilling.

Live view comes straight through the Blink app, complete with infrared night vision and two-way audio, while dual-zone enhanced motion detection means alerts arrive faster and only for the parts of the yard that actually matter.

An optional Blink Subscription Plan unlocks person detection through onboard computer vision, letting the camera tell the difference between a delivery driver at the door and a stray cat setting off the sensor for no good reason.

That subscription also comes bundled with a free 30-day trial for cloud video storage, and because this camera works with every Blink Sync Module on the market, it slots straight into an existing setup without needing a separate hub.

Anyone already running Alexa at home gets even more out of it too, since a compatible Echo Show or Alexa device can stream live video on command and let the camera be armed or disarmed entirely hands-free.

The real appeal here is how easily one more Outdoor 4 fits into a system a household may already be running, since every camera added at this price makes fuller coverage of a home’s exterior a much smaller ask than it used to be.
