It takes a standard 9v battery which makes it easier and cheaper to maintain in the long term. The fixing bracket works well and it has an extending aerial which I expect would boost the range if you needed it but its only 10m from my central unit so I didn't have any problems and use the antenna in its retracted state. Its perhaps not quite as beautiful as it might be without this antenna but overall I am very happy and it has been working reliably without any false positives so far. ### ⭐⭐⭐⭐⭐ Does the job. *by on Reviewed in the United Kingdom 24 April 2024* Does the job. ### ⭐⭐⭐⭐ Good replacement. *by on Reviewed in the United Kingdom 16 August 2022* Bought as a replacement. Does the job ok. ## Frequently Bought Together - KERUI Wireless Security PIR Motion Infrared Sensor Detector for Home Security Voice Burglar Alarm System 433mhz - KERUI 433MHz Wireless Door/Window Magnetic Sensor For GSM Home Security Alarm Systems - KERUI 115db DIY Wireless Home Security System,Indoor Outdoor Weather-Proof Siren,Window Door Sensors Motion Sensor,Shed Garage Alarm with Remote Control,Burglar Door Alarm for Hotel Shop House --- ## 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.at/products/54274664-wireless-security-pir-motion-infrared-sensor-detector-for-home-security](https://www.desertcart.at/products/54274664-wireless-security-pir-motion-infrared-sensor-detector-for-home-security) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-10*
