From the brand

EVEN BETTER with a SirenFob! Pair one or more siren products to your SirenFob, then pair one or more alarm products (such as door, motion, vibration sensors – ideal for vehicles, RVs, and other mobile applications or where internet is not available). *Additional YoLink devices required, not included.
NO WIFI, NO INTERNET, NO POWER? NO PROBLEM! Our patented Control-D2D device-to-device pairing, over our LoRa-based wireless network, allows for devices to be paired to each other, in such a way they will continue to operate, even if WiFi is flaky, the internet goes down, or the AC power goes out!
LONGEST RANGE, BY FAR! Only YoLink, powered by LoRa is capable of up to 1/4 mile range in open air, allowing you to locate the siren virtually anywhere on your property, with no concerns about WiFi signal or dependability
START SMART! A YoLink hub is required for full functionality, including for the app to work, to check battery level, etc, but your hub is compatible with a growing family of smart products for home and business! Search for B09FSS95G9 for a SpeakerHub (our audio, talking hub) or B07TQLKQLJ for the original Hub.
BATTERIES NOT INCLUDED: Use four alkaline or lithium AA batteries
