Setting it up was incredibly straightforward, and all components paired seamlessly. The wireless design is super convenient, and the range is excellent—even works perfectly in my detached garage. The alarm is loud enough to deter intruders, but not so loud that it feels excessive. I love that it’s customizable and expandable, so I can add more sensors if needed. It’s also compact and doesn’t look obtrusive when installed. For the price, this kit offers amazing value and peace of mind. Highly recommend it for anyone looking for an easy-to-use security system. 5/5 stars! ## Frequently Bought Together - KERUI Wireless Security Burglar Door Alarm System Kit for Garage Shed House Hotel Shop Apartment, Weatherproof Siren Horn with Remote Control Door Contact Sensor,Motion Sensor,Loud Up to 115db - KERUI Wireless Remote Control Working with KERUI Home Alarm System White 433 mHZ… - KERUI 433MHz Wireless Door/Window Magnetic Sensor For GSM Home Security Alarm Systems --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/410252739-home-siren-alarm-system-door-alarm-system-115-db-door](https://www.desertcart.us/products/410252739-home-siren-alarm-system-door-alarm-system-115-db-door) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-15*
