As we head into 2025, there aren’t many things preventing homeowners from building out a basic home security system. You can start small and cheap with the battery-powered Blink Outdoor 4. If you don’t mind that they’re refurbished (with the same one-year warranty as the new models), you can get two of them with a Sync Module 2 for $74.99 ($90 off) at Amazon, which is only $10 more than the all-time low. A single Blink Outdoor 4 retails for $99.99 new, and its lowest price is $39.99, so you’re still getting a slightly better value than usual.
The weatherproof Blink Outdoor 4 offers a 1080p wide-angle feed with motion detection, infrared night vision, and two-way audio. If you opt for a Blink Subscription Plan ($10 a month or $100 a year for Blink Plus, which is required to run multiple cameras), you’ll get person detection, up to 90 minutes of continuous live view, and unlimited cloud storage for up to 60 days. But if you have subscription fatigue, you can also save clips locally to a USB drive thanks to the included Sync Module 2. Blink says the cameras can last up to two years on just two AA batteries, too, which should make them easy to maintain over the long haul.
