Blink Sync Module XR is the first system hub to extend the range of your Blink Outdoor 4 wireless smart security cameras so you can see what’s happening around your entire property with ease. Enjoy 4x the coverage — Install cameras up to 1000 feet (open air)/400 feet (typical use) from your Sync Module XR, which is 4x farther than Blink cameras operating on WiFi alone. See live view 20% faster — XR technology runs on the 900MHz band, avoiding typical WiFi congestion, and unlocking 20% quicker access to live view, even at long distances.
