This is a three-camera Blink kit: two Outdoor 4 cameras plus one plug-in Mini 2K+ indoor camera, tied together by the Sync Module XR+. The XR+ hub runs on the 900MHz band instead of wifi, which Blink says gives up to 10x the range, up to 70% fewer disconnects in weak-signal spots, and up to 20% faster live view. The Outdoor 4 units run up to two years on the included Energizer lithium AA batteries, and clips can go to the cloud or to a microSD card in the hub. It suits large yards, detached garages and outbuildings where plain wifi cameras drop out; against standard wifi-only Blink kits the range is the headline, but resolution stays modest and the best features sit behind a subscription.

Owners of Blink's XR kits tend to praise the range and battery life, and say cameras stay connected where wifi cameras failed. Complaints center on subscription costs and the modest Outdoor 4 image quality.
This is a three-camera Blink security system. It includes two Outdoor 4 wireless cameras, one plug-in Mini 2K+ indoor camera with 2K video, and a Sync Module XR+ for extended range. Video resolution may vary.
Outdoor 4 cameras can be installed up to 2,700 feet (open air) or 1,700 feet (typical use) from the Sync Module XR+. That is 10x farther than Blink cameras operating on wifi alone. XR technology runs on the 900MHz band, which avoids typical wifi congestion. It gives up to 20% quicker access to live view where the wifi signal is poor, and up to 70% fewer disconnects in areas with poor wifi signal strength.
With the Sync Module XR+ and Energizer Lithium AA batteries, both included, Outdoor 4 can run up to two years on its batteries, even at long range. Clips can be stored in the cloud with a Blink plan (free 30-day trial, plan sold separately). They can also be stored locally with the Sync Module XR+ and a MicroSD card of up to 256 GB (sold separately). The Blink app controls up to 10 Blink devices and lets you arm, disarm and group cameras. The system works with Alexa for live view, arming and disarming, and motion-trigger routines.
