Blink Outdoor 4 XR 6-Camera System – $146.99 (65% off $419.99) · 4.1/5 · 4,585 reviews Amazon has the Blink Outdoor 4 XR 6-Camera System with Sync Module XR for $146.99. Also available in 1, 2, and 4-camera configurations. Six Outdoor 4 cameras running on the XR module's 900MHz band — up to 400 feet range in standard XR mode, up to 1,000 feet open-air in XR+ mode (though XR+ drops to 720p and disables two-way audio). Two-year battery life, 1080p, motion detection, two-way audio, local storage via microSD card in the XR module (sold separately), and Alexa support. No subscription required for basic recording to SD card. One detailed reviewer ran two accounts side-by-side for months testing subscription vs. no-subscription — the short version: motion detection works comparably with or without a subscription, but video is only viewable through the app with a subscription. Without one, clips go to the SD card and require pulling the card to view on a computer. Also: notification control applies to all cameras at once — you can't silence alerts for individual cameras without the subscription's snooze feature. Know this before you buy.
