YoLink Outdoor Security Siren & Smart Alarm Controller Kit - Loud 110 dB, Wireless, Battery-Powered, 1/4 Mile Range, Android-iOS App, Alexa, Google, IFTTT, Home Assistant, Hub Required!

• WIRE LESS! No wiring required, no external power supply required: the self-contained controller powers the siren and itself from four AA batteries!
• 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
